| |
| Version 5.4 |
| |
| IMPROVEMENTS: |
| |
| * New process uptime test added. Allows to do some action in |
| the case that the process uptime matches the given limit. |
| For example to restart the process once per 3 days: |
| if uptime > 3 days then restart |
| |
| * Linux uCLibc support: use internal getloadavg implementation |
| in the case that the system libc doesn't implement it. |
| |
| BUGFIXES: |
| |
| * The monit hostname will fallback to plain machine's hostname if the |
| lookup for FQDN hostname didn't found matching entry. The problem |
| was, that based on the order in the /etc/hosts the FQDN lookup |
| returned sometimes 'localhost' instead of the FQDN hostname. |
| |
| * The CPU usage for multi-threaded processes on multi-core machine was |
| reported incorrectly in the case that the process used more CPU |
| resources then equivalent to one core. Thanks to Tom Pepper for patch. |
| |
| * The content match test now sends one event per cycle and pattern. |
| Even if there are multiple lines matching the same pattern, only |
| one event will be generated. Also the event rate is fixed now, so |
| it is possible to require match for X cycles before generating the |
| event. |
| |
| * The /proc/ files content match test was skipped, as the file size on |
| the procfs is 0, so monit supposed that there is no content to read. |
| |
| * FreeBSD: If the monitored process had children with multiple threads, |
| the total memory usage was reported incorrectly. Thanks to Phil Kulin |
| for reporting the problem. |
| |
| * Allow reading status and perform Monit actions when using client SSL |
| certificate. Previously, if Monit http server was setup to use ssl |
| and a client cert, status and action failed. Thanks to Markus Linnala |
| for initial patch. |
| |
| * When the process is starting/stopping, do the process state check more |
| effectively to not stress the low power devices with aggresive polling. |
| Thanks to Thomas Petazzoni for initial patch. |
| |
| * Make the process start/stop wait resistant to large time changes. |
| |
| * Compilation: If PAM is enabled but the PAM headers or library are not |
| found by the configure script, it will report error. |
| |
| * Cross-compilation: the configure checks the setjmp and vsnprintf with |
| test program which usually cannot be executed when cross-compiling |
| for other architecture. The configure script now takes the following |
| arguments which allow to specify whether the setjmp works on this |
| platform and whether the vsnprintf is C99 compliant. Thanks to |
| Thomas Petazzoni for patch. |
| ./configure \ |
| libmonit_cv_setjmp_available=[yes|no] \ |
| libmonit_cv_vsnprintf_c99_conformant=[yes|no] |
| |
| * Manual page language fixes. Thanks to Jonathan Boulle for patch. |
| |
| |
| |
| Version 5.3.2 |
| |
| BUGFIXES: |
| |
| * Fix bug #34801: The file content match test did reset of the |
| read position in the case that the unmonitor or stop action |
| was done. When the file monitoring was enabled again, the |
| content match test was applied to the content which was |
| tested already. |
| |
| * Log error details in the case that the name resolving failed. |
| |
| * Fix the system cpu usage statistics when pattern based process |
| check is used and the service is restarted. Thanks to Wayne |
| Lawrence for report. |
| |
| * AIX 6.1 compile fix. Thanks to Benedikt Wegmann for patch. |
| |
| * Debian Bug#652715: "include files not found" warning. Do not |
| display the warning if the include directory is empty. |
| |
| |
| |
| Version 5.3.1 |
| |
| IMPROVEMENTS: |
| |
| * Log the particular connection attempt failure in debug mode |
| when the retry is enabled. |
| |
| * Monit can deliver events and status to independent M/Monit |
| instances if multiple mmonit URLs are set: |
| set mmonit https://user1:pass1@mmonit1/collector |
| https://user2:pass2@mmonit2/collector |
| |
| BUGFIXES: |
| |
| * The ICMP echo (ping) test may report false positive error |
| if the machine where Monit is running has heavy ICMP |
| traffic generated by other applications. |
| |
| * The file content match test will be performed even on the |
| existing content when Monit starts. The last position is |
| saved to the statefile, so monit won't generate alert |
| after restart. Note that when you start the monit 5.3.1 |
| the first time, it can do actions for content match which |
| was handled by previous monit version already as the |
| previous monit versions didn't saved the position. |
| |
| * Make the monitoring state persistent for manual mode services. |
| |
| * Display the memory usage total % in the status overview. |
| The memory usage in kB displayed the total already, so the |
| percentage didn't match. |
| |
| * Fix the HTML overview page alignment in the Internet Explorer. |
| Thanks to Darhl Thomason for patch. |
| |
| * Extend the SSL library search path for Debian Sid. |
| |
| * Fix Solaris 10 compilation and Sun Studio support. |
| |
| * Fix sporadic SSL routines:func(169):reason(161) errors |
| |
| * If MySQL protocol test failed, report the correct MySQL |
| error code. Thanks to Vitaly Lipatov for patch. |
| |
| |
| Version 5.3 |
| |
| * New 'check program' statement added. Allows to check the exit |
| status of an external program or script from Monit. |
| |
| * Added crontab style support for individual services. You can |
| now specify when an individual service should run its checks |
| (or not run). You can now, for instance, specify that apache |
| should be checked continuously, except between 1AM-5AM on |
| Sunday. |
| |
| * Connection retry option added. Allows to retry a network |
| connection in the same testing cycle before reporting an error. |
| |
| * Detailed protocol connection errors are now included in alerts. |
| |
| * The HTML overview page displays the CPU and memory total now |
| (including children), so real service related usage is displayed |
| also for services which spawn worker processes, such as Apache |
| or Spamassassin. |
| |
| * HTML view improvements |
| |
| * Fix MySQL protocol test: MySQL 5.5.12 returns new error code in |
| the case of authentication failure. |
| |
| * Fix Debian bug #621047: monit fails to build after SSLv2 removal |
| |
| * Fix crash on Solaris which may occur if the system load is zero. |
| Thanks to Paul Sun for report. |
| |
| * The stacktrace logging on error is disabled in -v (verbose) mode |
| as it was too verbose for common service debugging tasks, it can |
| be enabled using -vv option. |
| |
| * Improve how fast Monit check if a program was started or stopped. |
| Thanks to Michael Renner for patch. |
| |
| * Fix the monitoring state presentation during service restart which |
| temporarily displayed "Not monitored", whereas the monitoring was |
| enabled. |
| |
| * The "data collected" is updated only if the check was not skipped. |
| |
| |
| Version 5.2.5 |
| |
| * Fix process match check - when the monitored process failed and |
| was restarted by Monit, Monit didn't recognized it is running |
| after the restart and reported start failure (similar on stop). |
| Thanks to Kenichi Futatsumori for report and helping to root |
| cause the problem. |
| |
| * Fix Debian #617259: symbolic links in the filesystem check doesn't |
| work. Thanks to Sergey B Kirpichev for report. |
| |
| * Fix Debian bug #614984: smtp protocol test issues both EHLO and |
| HELO. Thanks to Sergey B Kirpichev for report. |
| |
| * Fix bug #32583: Multiple SIP OPTIONS messages use the same header |
| data. Thanks to Hugh Waite for patch. |
| |
| * Try harder to get FQDN hostname for the host where monit is running. |
| The hostname in the $HOST variable which is used in the mail sender |
| may thus change. Thanks to Sergey B Kirpichev for patch. |
| |
| * AIX: Fix the time display which was off by GMT difference. Thanks |
| to Helen Chen for report. |
| |
| * AIX: Fix the M/Monit heartbeat. Thanks to Helen Chen for report. |
| |
| * Support symbolic link to monit configuration file. |
| |
| * Fix crash when monit daemon start delay option was used and monit |
| was signalized to stop before the start delay passed. Thanks to |
| John Schult for report. |
| |
| |
| |
| Version 5.2.4 |
| |
| NEW FEATURES AND FUNCTIONS: |
| |
| * Added the "procmatch" CLI command which allows for easy testing |
| of pattern for process match check. The command takes regular |
| expression as an argument and displays all running processes |
| matching the pattern. Example usage: |
| $ monit procmatch "iChatAgent" |
| |
| * Set the default log file mask to 0640 (originally it was 0664). |
| Thanks to Sergey B Kirpichev. |
| |
| * Reduced monit memory footprint by ca. 10%. |
| |
| BUGFIXES: |
| |
| * FreeBSD, NetBSD, OpenBSD, MacOSX, Solaris filesystem check fix: |
| If block/character device was used in the filesystem path instead |
| of mountpoint, monit reported usage of wrong filesystem. |
| |
| * NetBSD filesystem check: Fix space usage report. |
| |
| * Fix memory usage monitoring in OpenVZ VPS 2.6.32 virtual hosts. |
| Thanks to Kelly for report. |
| |
| * If the protocol test failed, show the request in the event. Thanks |
| to Marco for report. |
| |
| * Randomize the mail message id to prevent duplicates in the case, that |
| the same hostname is used on multiple hosts running monit and messages |
| are generated in the same second in parallel. Thanks to Sergey B |
| Kirpichev. |
| |
| * Spelling fixes. Thanks to Sergey B Kirpichev. |
| |
| |
| |
| Version 5.2.3 |
| |
| BUGFIXES: |
| |
| * Mysql protocol test supports mysql 5.5.x and newer now. |
| |
| |
| |
| Version 5.2.2 |
| |
| BUGFIXES: |
| |
| * Fix crash on MacOSX |
| |
| * ICMP echo test (ping): |
| - bug #31128: do not log error if different response type is received |
| - bug #31129: do not require root to use ping test. Privilege to create |
| raw socket is still required, but on some platforms such as Solaris it |
| can be granted to non-root users too. If the user has no permission to |
| perform ping, monit will skip the icmp test and log message (in debug |
| mode only). |
| |
| * rsync protocol test: |
| - wait for full server response and verify exit was received |
| - bug #31249: send full version to rsync server. Thanks to John Hall |
| for report |
| |
| |
| |
| Version 5.2.1 |
| |
| BUGFIXES: |
| |
| * HTTP and URL protocol tests: Fixed a problem where HTTP protocol |
| tests using a specific request always failed. This bug may also |
| affect URL tests. The problem was caused by faulty URL encoding. In |
| the process of fixing this bug the new feature that allowed slash in |
| service names has been reverted and instead will be added in a later |
| release. |
| |
| |
| |
| Version 5.2 |
| |
| NEW FEATURES AND FUNCTIONS: |
| |
| * Added support for monitoring processes without pidfile using pattern |
| matching. You can use POSIX regular expressions or string matching |
| process name with arguments as provided by the 'ps' utility. If the |
| pattern matches multiple processes, the first match is used. |
| Example: |
| check process debian |
| matching "/usr/lib/vmware/bin/vmware-vmx .*deb.vmx" |
| |
| * Added support for swap monitoring. Example: |
| check system myserver |
| if swap usage > 25% then alert |
| |
| * Allow to override the default action when service doesn't exist. The |
| default action is restart, it can be customized with following |
| statement: |
| if [does] not exist [[<x> times within] <y> cycles] then <action1> |
| |
| * Monit automatically registers credentials with M/Monit now, so it's |
| not necessary to set it manually in M/Monit anymore. To disable |
| credentials registration: |
| set mmonit https://monit:monit@10.0.0.1:8443/collector |
| and register without credentials |
| |
| * Added memcache protocol test. Thanks to Sébastien Debrard for the |
| patch. |
| |
| * Added openssl FIPS to Monit httpd. Thanks to Lior Okman for the |
| patch. |
| |
| * The 'check system' can now use start/stop program statements too. |
| |
| * Added the option to set the "Reply-To" mail header in mail-format. |
| |
| * Display backtrace on error if debug mode is enabled (requires |
| backtrace support in libc) |
| |
| BUGFIXES: |
| |
| * Show real process uptime - formerly the presented uptime was based |
| on create and modify timestamp of process' pidfile which provides |
| invalid uptime if the pidfile is replaced and process keeps running |
| with original PID. Thanks to Nima Chavooshi for report. |
| |
| * When user triggered action for some service (such as stop) and |
| before that action completed user triggered another action for the |
| same service (such as start), the second action has been ignored. |
| Monit will not accept new action and return temporary error until |
| the previous action completed. |
| |
| * If process resource usage gathering failed, retry next cycle as the |
| error can be temporary. |
| |
| * Fixed sporadic failures when SSL was used. |
| |
| * ICMP echo test (ping): |
| - fixed sporadic false positive/negative |
| - removed limit of 20 pings per cycle |
| |
| * DNS test: |
| - accept NS root request refusal as correct response because |
| server reacts on request |
| - accept authority answer as alternative to record. Thanks to |
| Nick Osborn for patch |
| |
| * RADIUS test fix. Thanks to Alan DeKok for patch. |
| |
| * M/Monit heartbeat is fully independent of testing cycle now to |
| prevent false positive when service test blocks. |
| |
| * Fixed SMTP STARTTLS protocol, required for servers that adhere |
| strictly to RFC 3207 4.2. Thanks to Lorenzo A. Sedano Cadinanos for |
| patch. |
| |
| * Service name: |
| - allow the service name to start with "/" |
| - fixed handling of the service names which contain "/" in the |
| name in Monit web interface. Thanks to Artyom Khafizov for |
| patch. |
| |
| * When 'check system' is not defined, monit adds it automatically |
| using hostname for service name. If existing service was defined |
| with the same service name (matching hostname), monit didn't added |
| the entry and reported confusing error message pointing to the end |
| of configuration file. Thanks to Thorsten Kampe for report and help. |
| |
| * Remove extra NL characters from message when resource succeeded |
| event is sent. The extra NL character may break the mail headers. |
| Thanks to Hanno Boeck for patch. |
| |
| * Fixed display of cpu user/system/wait usage which temporarily |
| displayed -1.0% between two monitoring cycles while cpu monitoring |
| was initializing. Thanks to Marcus Muelbuesch for report. |
| |
| * Fixed display of port response time as -1 if 'monit status' was |
| called in the middle of service test. |
| |
| * Fixed display of service initializing state after monit start or |
| reload. |
| |
| * Fixed MONIT_DESCRIPTION environment variable. Thanks to Marco |
| Roeland for patch |
| |
| * AIX: |
| - fixed compilation |
| - fixed system load average monitoring |
| - fixed ICMP echo test |
| |
| * Mac OS X: |
| - allow monitoring of system-wide load average, cpu and memory |
| usage even if |
| Monit is running as non-root user |
| |
| * NetBSD: |
| - fixed ICMP echo test |
| |
| |
| |
| Version 5.1.1 |
| |
| BUGFIXES: |
| |
| * Fix FTP protocol test. Thanks to Axel Reinhold for report. |
| |
| * Fix the HTTP protocol test's hostheader option which was added in 5.1. |
| Thanks to Naoya Nakazawa for report. |
| |
| * Removed warning about missing system service check. Missing system service |
| check is not error and it shouldn't be reported as such. |
| |
| * Fix manual page formating. Thanks to Stefan Alfredsson for report. |
| |
| |
| |
| Version 5.1 |
| |
| NEW FEATURES AND FUNCTIONS: |
| |
| * It is now possible to define any action for the restart timeout rule. |
| Multiple restart timeout rules can also be defined. Example: |
| if 3 restarts within 5 cycles then exec "/foo/bar" |
| if 8 restarts within 10 cycles then unmonitor |
| |
| * Service can be added to multiple groups. Thanks to Brad Gessler |
| for suggestion. Syntax: |
| check filesystem wwwdata with path /www |
| group www |
| group filesystem |
| |
| * Added GPS protocol test. Thanks to Sebastien Debrard for patch. |
| |
| * Added RADIUS protocol test. Thanks to Alan DeKok for patch. Example syntax: |
| check process radiusd with pidfile /var/run/radiusd.pid |
| start program = "/etc/init.d/freeradius start" |
| stop program = "/etc/init.d/freeradius stop" |
| if failed |
| host 127.0.0.1 port 2000 type udp protocol radius secret testing1234 |
| then alert |
| if 5 restarts within 5 cycles then timeout |
| |
| * The HTTP protocol test now supports a hostheader option which allows to |
| override Host header in HTTP request. It can be used for example |
| to test a farm of HTTP servers by IP addresses and to set specific |
| Host header. Thanks to Brady Catherman for patch. Example: |
| if failed host 192.168.1.100 protocol http hostheader "example.com" then alert |
| |
| * If an error occur during Monit command-line execution, report the error |
| and exit with 1, so it is possible to react if Monit is used from a script. |
| On success, 0 is returned as usual. Previously, Monit always exited with |
| 0 even if an error occurred. |
| |
| * Do not require SSL version type when specifying SSL communication with M/Monit |
| (SSL version is set to auto). |
| |
| * If the Monit http interface failed to start, provide more details about |
| the reason. |
| |
| BUGFIXES: |
| |
| * Support resource monitoring (cpu usage, etc.) when Monit is running |
| inside virtual environment. Tested on: |
| - FreeBSD jail |
| - Solaris zone |
| - Linux Vserver |
| |
| * Fix #26752: inside Solaris Zone, Monit failed to detect children |
| and computed host memory wrong |
| |
| * On Solaris, FreeBSD, NetBSD and OpenBSD, Monit no longer needs to run as root user |
| in order to be able to watch process resource usage (cpu and memory). |
| |
| * Send heartbeat to M/Monit even if Monit is busy in a long testing cycle to prevent |
| false alerts about non-responsive Monit agent. |
| |
| * Fixed SMTP protocol test which may sometimes incorrectly |
| report ESMTP protocol failure. Thanks to Axel Reinhold for |
| report. |
| |
| * Fixed content match check which reported only first |
| match during the same cycle. Thanks to Pavel Shevaev for |
| report. |
| |
| * Allow for the use of complete SSL certificate chains. |
| Thanks to Lawrence Tan for patch. |
| |
| * Added support for multiline greetings to FTP protocol test. |
| Thanks to Giovanni D'Cristina for report. |
| |
| * Fix Debian Bug #541139: uses gethostbyname() and thus does |
| not work with "options inet6" in /etc/resolv.conf. Thanks to |
| Michael Stapelberg for patch. |
| |
| * If Monit configuration allowed http interface access for a read-only |
| user and it was specified as the first allow entry, Monit command line |
| commands failed because it used the read-only account so commands |
| like start, stop, etc. were rejected. Monit will now use full access |
| regardless of allow option order. Thanks to Thorsten Kampe for report. |
| |
| * Passive monitoring mode fixed. Thanks to Nelson Vale for report. |
| |
| * Fixed #27784: wait_start/wait_stop can advance too quickly. |
| Thanks to Randy Puro for report. |
| |
| * Solaris resource usage fixed when Monit was compiled with optimizations enabled. |
| |
| * Fixed #28369: escape XML properly |
| |
| * Check service name uniqueness when 'check system' is missing in monitrc and virtual |
| system service with name set to local hostname is added. Thanks to Marcus Muelbuesch |
| for report. |
| |
| * Fix crash when queued event delivery was retried for service which was no longer |
| configured in Monit. |
| |
| |
| |
| Version 5.0.3 |
| |
| BUGFIXES: |
| |
| * Fixed #26664: crash on service timeout or unmonitor action |
| (introduced in 5.0.2). Thanks to Bretislav Kubesa and |
| Michael Shigorin for report. |
| |
| * Removed the configure --without-resource option. If the user |
| who is running Monit doesn't have permissions to check the |
| processes state, the related checks are disabled dynamically. |
| |
| |
| |
| Version 5.0.2 |
| |
| BUGFIXES: |
| |
| * 35 improvements based on code scan with Klocwork |
| (http://www.klocwork.com/) which we were evaluating. |
| Huge thanks to Klocwork for their great product. |
| |
| * Fixed #26382: if start or stop script for some service didn't |
| exist, monit logged error during configuration file parsing and |
| refused to start. Monit now just logs warning and continues. |
| |
| |
| |
| Version 5.0.1 |
| |
| BUGFIXES: |
| |
| * Fixed a bug where Monit did not stop logging succeeded events. |
| This bug occurred if PID, PPID, timestamp or size change tests |
| were used and failed and then succeeded again. |
| |
| |
| |
| Version 5.0 |
| |
| NEW FEATURES AND FUNCTIONS: |
| |
| * M/Monit support added. If you run Monit on more than one |
| server, you can use M/Monit to manage and control all your |
| Monit enabled servers from one simple Web Interface. See |
| http://mmonit.com/ for details. |
| |
| * Support use of symbolic links in filesystem check. Thanks to |
| Aleksander Kamenik for suggestion. Example: |
| check filesystem rootfs path |
| /dev/disk/by-uuid/4ef973f7-67d1-4bb0-8223-cb1c692b72e4 |
| if space usage > 95% then alert |
| if inode usage > 95% then alert |
| |
| * If no 'set mailserver' was defined in monitrc, Monit tried to |
| fallback to localhost:25 SMTP server. This fallback was removed |
| since it may be confusing. If you want to deliver mail alerts |
| from Monit, the 'set mailserver' option is necessary. In case |
| it is missing, Monit will log appropriate error and hint to add |
| it. |
| |
| * The generic send/expect protocol test limited the expect input |
| to 256 bytes. It's possible to set the input buffer for expect |
| globally - for example: set expectbuffer 20 kb Thanks to Asil |
| Carlin for suggestion. |
| |
| * The following event types were added CONTENT, FSFLAGS, PID and |
| PPID and the following generic event types CHANGED and MATCH were |
| removed and replaced by the above types and with the existing SIZE, |
| CHECKSUM, TIMESTAMP events so the information is more specific |
| The event types are internal to Monit and unless you have used |
| either CHANGED or MATCH event in your alert filters, no change |
| is necessary (alerts are delivered as usual, the tests just use |
| different types internally). |
| |
| * Monit now generates a unique id on first start and store the id |
| in a permanent file. This id is used in protocol communication |
| between Monit and M/Monit to pair a Monit instance with it's |
| host entry in M/Monit. By default the id file is placed in |
| $HOME/.monit.id. The location can be changed by using the set |
| idfile statement, for example: |
| set idfile /var/monit.id |
| |
| * Monit now keep its service monitoring state even on Monit |
| restart. Previously Monit dropped the state when it was stopped |
| correctly. Services in manual monitoring mode will remember the |
| monitoring state across Monit restarts. If Monit is used in a |
| cluster, it is recommended to place the state file in a |
| temporary filesystem incase the primary machine will crash and |
| the the spare machine takeover, the state will be dropped on |
| reboot for the crashed machine and the services in manual |
| monitoring mode won't be started on reboot. For example the |
| "set statefile /tmp/monit.state" can be used to place the state |
| file in the /tmp/ filesystem. |
| |
| * Added a protocol test for testing the LMTP protocol. Thanks |
| to Fco. Javier Felix for patch. |
| |
| * Added the start delay option for daemon statement which allows |
| to pause Monit on its startup for a while. If monitored |
| services are started by init scripts in parallel on system |
| boot, Monit may be too fast and detect that the service is not |
| running (yet) and restart the service. Note that it's still |
| recommended Monit is setup to be responsible for service |
| startup (that is, don't use init to start Monit controlled |
| services, instead use Monit). This will ensure correct startup |
| without need for a start delay since Monit will have full |
| control of service startup. Many users start services from init |
| on boot anyway, so in such cases this option will solve their |
| problems. Default start delay is 0 which corresponds to the |
| current behavior. Example syntax which will make Monit wait one |
| minute before starting its first monitoring cycle: |
| --8<-- |
| set daemon 5 with start delay 60 |
| --8<-- |
| Thanks to Fco. Javier Felix for patch. |
| |
| * Added PAM support for Monit http interface authentication. Note |
| that PAM is not supported on all platforms - currently works on |
| Linux, Mac OS X, FreeBSD, NetBSD. Monit uses the PAM service "monit". |
| Here is a Monit PAM service example for Mac OS X which is able |
| to authenticate system users for Monit access - |
| /etc/pam.d/monit: |
| --8<-- |
| # monit: auth account password session |
| auth sufficient pam_securityserver.so |
| auth sufficient pam_unix.so |
| auth required pam_deny.so |
| account required pam_permit.so |
| --8<-- |
| And configuration for monitrc which allows only group admins |
| to access the http interface: |
| --8<-- |
| set httpd port 2812 allow @admin |
| --8<-- |
| See the PAM manual page for details on how to configure the PAM |
| service on your system and the available PAM plugins. Thanks to |
| Wilhelm Meier for patch. |
| |
| * Added more detailed reports for Monit resource tests on service |
| recovery. Thanks to Lars Kotthoff for patch. |
| |
| * Set locale to C. |
| |
| * Added a protocol test for testing the SIP protocol which is |
| used by popular communication servers such as Asterisk and |
| FreeSWITCH. We received two patches for this protocol and have |
| taken code from both and merged them. Many thanks to Bret |
| McDanel and to Pierrick Grasland for supplying the patches. |
| |
| * Added MONIT_DESCRIPTION to the list of environment variables |
| available to programs started by monit. Thanks to Morten |
| Bressendorff Schmidt for patch. |

| * If a service group is specified for Monit CLI action, |
| Monit no longer requires the "all" verb, so the following |
| command is possible: |
| monit -g web stop |
| If group is not specified (i.e. the -g option is omitted), the |
| service name or "all" is still required as a safeguard. |
| |
| * Added an option to the 'set mailserver' statement so it is |
| possible to override the hostname used in SMTP EHLO/HELO and in |
| the Message-ID header when sending mail. Monit defaults to use |
| the localhost name. I.e. what you get when executing this |
| command 'uname -n'. Overriding the host name can be useful if |
| the host does not have a DNS entry and if the receiving |
| mailserver uses DNS verification as spam protection. The new |
| override option is: |
| set mailserver foo.bar.baz using hostname "my.monit.host" |
| |
| * A new Event_Action type was added which reports actions |
| performed on Monit's administrator request (either via web |
| interface or CLI). If you don't want to received these events, |
| you can set the mail-filter for "action" event type. |
| |
| * NOTA BENE: Monit start action is synchronous now. This improves |
| the startup sequence for dependent services, since Monit will |
| wait for parent service to start before trying to start the |
| child. |
| |
| * It is now possible to define execution timeout for start and |
| stop commands. That is, how long Monit will wait after |
| executing a command before it assume execution failed. If the |
| timeout option is omitted, Monit defaults to 30 seconds. You |
| can override the timeout for example for services which are |
| starting slower. |
| Example syntax: |
| start program = "/bin/foo start" with timeout 60 seconds |
| |
| * The event passed state is renamed to succeeded as this name |
| more reflects the state of things. |
| |
| * The device service test is renamed to filesystem. |
| |
| BUGFIXES: |
| |
| * Some linux virtualization platforms report CPU count as 0. |
| Monit then dynamically disabled CPU usage monitoring. In such |
| case we now override the CPU count from 0 to 1 so resource |
| usage monitoring can continue. Thanks to Jenny Hopkins for |
| report. |
| |
| * Increased the server socket backlog queue which will make Monit |
| able to handle more services. Thanks to Jochen Kramer. |
| |
| * Fixed #24866: Email messages such as: cpu wait usage check |
| succeeded [current cpu wait usage=17.4%] were displayed as |
| "...usage<SOMEGARBAGE>.4%". The problem was incorrect transfer |
| encoding header in the email (the body itself was OK). Thanks |
| to Dave Cheney for report. |
| |
| * When a Monit shutdown requested was issued while Monit were |
| working and testing services, Monit did not shutdown until all |
| work were done, i.e. until all services were tested. Monit will |
| now shutdown faster - as soon as it finish testing the current |
| service. |
| |
| * Monit blocked/unblocked SIGTERM, SIGINT SIGHUP and SIGUSR1 |
| signals during operation to protect certain code sections. When |
| a signal was sent during such a time, for example to stop |
| Monit, it was dropped and had to be retried in order to stop |
| Monit. This limitation is now removed and signals will be |
| processed at any time. Thanks to Nicola Tiling for report. |
| |
| * If the Monit httpd allow option did not include a |
| user:password, Monit CLI logged the following error (even if |
| the action was performed anyway): |
| Cleartext credentials needed for basic authorization! |
| This error was false - even access restriction based on |
| host/net is sufficient - user and password is just one of |
| possible options (not requirement). Thanks to Gilad Benjamini |
| for report. |
| |
| * Allow localhost as a value for the host header in the http |
| protocol test instead of setting an empty host header and let |
| the http server decide |
| |
| * The 'if changed checksum ...' test can now be used even if a |
| monitored file doesn't exist at Monit startup. Thanks to Joe |
| Shang for report. |
| |
| * If both event handlers (M/Monit and mail alerts) temporarily |
| failed at once and event queue was enabled, events will be |
| stored in the queue and delivered in the next cycle. However, a |
| bug caused delivery to be retried for every cycle for both |
| handlers if just one of them was recovered. Monit could then |
| deliver the same message multiple times until both handlers |
| recovered. The problem is now fixed and only one copy of the |
| event is sent even if only one handler did recover. |
| |
| * Make unit in size test optional and default to byte unless |
| specified. So it is possible to write, if size > 1000 then .. |
| |
| * Fixed handling of invalid input files in event queue handler. |
| Thanks to Fco.Javier Felix for patch. |
| |
| * Set the content type to text/html for Monit web interface POST |
| responses. Thanks to Rich Drummond for patch. |
| |
| * Fixed #23530: configure script will return error if bison, |
| byacc or yacc are not found at Monit compile time. |
| |
| * Fix CPU and memory monitoring on Solaris (it was disabled on |
| Monit start) |
| |
| * AIX fixes and extensions, Monit should run on AIX without |
| problems, including cpu, memory and filesystem monitoring |
| (tested with AIX 5.3). Thanks to Brian Downey for support |
| and help. |
| |
| * HP-UX fixes and extensions, Monit should run on HP-UX without |
| problems, including cpu, memory and filesystem monitoring. |
| Thanks to Brian Downey for support and help. |
| |
| * Fixed #23467: Don't exit, only issue a warning if the "include" |
| statement did not find any files to include. |
| |
| * Fixed #23530: Event queue did not work with the default |
| unlimited slots. |
| |
| * Fixed #23617: The process cpu usage is initializing in the |
| first cycle so the value is set to 0% - if the 'cpu usage < |
| xyz%' test was used to check that the process usage is higher |
| then given level, it was always true. Monit now skips the |
| process cpu usage check in the first cycle. |
| |
| * Make sure Monit alerts has a unique message id. Thanks to Steve |
| Purcell for report |
| |
| * Fixed possible crash when Monit is watching VPS environment on |
| Linux which reports number of CPUs as 0. Thanks to Marius |
| Schmidt for report. |
| |
| * Cleanup event states during a service stop/unmonitor so old |
| events are not sent when the service is started/monitored again. |
| |
| * Fixed #21989: Monit could start two instances of the process |
| when service restart is performed and the process is starting |
| slowly. Thanks to Nick Upson, Aaron Scamehorn and David Greaves |
| for report. |
| |
| * Fixed #21550: Fix crash when Monit event queue contained an |
| empty file. Thanks to Douglas J Hunley for report. |
| |
| * Fixed possible crash when the 'if changed checksum' test was |
| used along with restart action. Thanks to Brian Candler for |
| report. |
| |
| * Fixed #22075: Allow using a mail address as username when using |
| SMTP authentication. |
| |
| * Fixed #22191 and #19823: If the file content test does not match |
| anymore, reset the service error state. (Previous versions did |
| not clear the error state and kept showing a match in the status |
| listing and in the http interface). |
| |
| * The 'if changed size ...' test can now be used even if the |
| monitored file does not exist on monit's start. |
| |
| * If a htpasswd file is used to control Monit http interface |
| access and the hash type is set to MD5 but the file contains |
| wrong format (non-MD5), report the error and keep running. |
| Formerly Monit exited with an assert exception. Thanks to |
| Adrian Bridgett for report. |
| |
| BACKWARD INCOMPATIBLE CHANGES: |
| |
| * The current CPU usage test which checked the cpu usage of the |
| process itself plus the cpu usage of child processes was |
| renamed to TOTALCPU (otherwise it works the same). The new CPU |
| usage test checks the CPU usage of the process itself only. |
| This change was introduced to align the syntax with MEMORY and |
| TOTALMEMORY tests and to allow to test the CPU usage of |
| processes which fork child processes but the user don't want to |
| include children (such as Mythtv). Users who are using the CPU |
| check for services like Apache webserver to watch total cpu |
| utilization (including children) should rename the CPU |
| statement in their configuration to TOTALCPU. |
