| <h2 class="chapter">18 Syslog</h2> |
| |
| <p>This chapter describes facilities for issuing and logging messages of |
| system administration interest. This chapter has nothing to do with |
| programs issuing messages to their own users or keeping private logs |
| (One would typically do that with the facilities described in |
| <a href="I_002fO-on-Streams.html#I_002fO-on-Streams">I/O on Streams</a>). |
| |
| <p>Most systems have a facility called “Syslog” that allows programs to |
| submit messages of interest to system administrators and can be |
| configured to pass these messages on in various ways, such as printing |
| on the console, mailing to a particular person, or recording in a log |
| file for future reference. |
| |
| <p>A program uses the facilities in this chapter to submit such messages. |
