.SH "DESCRIPTION"
.SS rdma statistic [object] show - Queries the specified RDMA device for RDMA and driver-specific statistics. Show the default hw counters if object is not specified

.PP
.I "DEV"
- specifies counters on this RDMA device to show.

.I "PORT_INDEX"
- specifies counters on this RDMA port to show.

.SS rdma statistic <object> set - configure counter statistic auto-mode for a specific device/port
In auto mode all objects belong to one category are bind automatically to a single counter set.

.SS rdma statistic <object> bind - manually bind an object (e.g., a qp) with a counter
When bound the statistics of this object are available in this counter.

.SS rdma statistic <object> unbind - manually unbind an object (e.g., a qp) from the counter previously bound
When unbound the statistics of this object are no longer available in this counter; And if object id is not specified then all objects on this counter will be unbound.

.I "COUNTER-ID"
- specifies the id of the counter to be bound.
If this argument is omitted then a new counter will be allocated.

.SH "EXAMPLES"
.PP
rdma statistic show
.RS 4
Shows the state of the default counter of all RDMA devices on the system.
.RE
.PP
rdma statistic show link mlx5_2/1
.RS 4
Shows the state of the default counter of specified RDMA port
.RE
.PP
rdma statistic qp show
.RS 4
Shows the state of all qp counters of all RDMA devices on the system.
.RE
.PP
rdma statistic qp show link mlx5_2/1
.RS 4
Shows the state of all qp counters of specified RDMA port.
.RE
.PP
rdma statistic qp show link mlx5_2 pid 30489
.RS 4
Shows the state of all qp counters of specified RDMA port and belonging to pid 30489
.RE
.PP
rdma statistic qp mode
.RS 4
List current counter mode on all devices
.RE
.PP
rdma statistic qp mode link mlx5_2/1
.RS 4
List current counter mode of device mlx5_2 port 1
.RE
.PP
rdma statistic qp set link mlx5_2/1 auto type on
.RS 4
On device mlx5_2 port 1, for each new QP bind it with a counter automatically. Per counter for QPs with same qp type in each process. Currently only "type" is supported.
.RE
.PP
rdma statistic qp set link mlx5_2/1 auto off
.RS 4
Turn-off auto mode on device mlx5_2 port 1. The allocated counters can be manually accessed.
.RE
.PP
rdma statistic qp bind link mlx5_2/1 lqpn 178
.RS 4
On device mlx5_2 port 1, allocate a counter and bind the specified qp on it
.RE
.PP
rdma statistic qp unbind link mlx5_2/1 cntn 4 lqpn 178
.RS 4
On device mlx5_2 port 1, bind the specified qp on the specified counter
.RE
.PP
rdma statistic qp unbind link mlx5_2/1 cntn 4
.RS 4
On device mlx5_2 port 1, unbind all QPs on the specified counter. After that this counter will be released automatically by the kernel.
