Описание (Description)
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
DEV - specifies counters on this RDMA device to show.
PORT_INDEX - specifies counters on this RDMA port to show.
FILTER_NAME - specifies a filter to show only the results
matching it.
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. The "off" is global for
all auto modes together. Not applicable for MR's.
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. Not applicable for MR's.
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. Not applicable for
MR's.
COUNTER-ID - specifies the id of the counter to be bound. If
this argument is omitted then a new counter will be allocated.
Примеры (Examples)
rdma statistic show
Shows the state of the default counter of all RDMA devices on
the system.
rdma statistic show link mlx5_2/1
Shows the state of the default counter of specified RDMA port
rdma statistic qp show
Shows the state of all qp counters of all RDMA devices on the
system.
rdma statistic qp show link mlx5_2/1
Shows the state of all qp counters of specified RDMA port.
rdma statistic qp show link mlx5_2 pid 30489
Shows the state of all qp counters of specified RDMA port and
belonging to pid 30489
rdma statistic qp show link mlx5_2 qp-type UD
Shows the state of all qp counters of specified RDMA port and
with QP type UD
rdma statistic qp mode
List current counter mode on all devices
rdma statistic qp mode link mlx5_2/1
List current counter mode of device mlx5_2 port 1
rdma statistic qp set link mlx5_2/1 auto type on
On device mlx5_2 port 1, for each new user QP bind it with a
counter automatically. Per counter for QPs with same qp type.
rdma statistic qp set link mlx5_2/1 auto pid on
On device mlx5_2 port 1, for each new user QP bind it with a
counter automatically. Per counter for QPs with same pid.
rdma statistic qp set link mlx5_2/1 auto pid,type on
On device mlx5_2 port 1, for each new user QP bind it with a
counter automatically. Per counter for QPs with same pid and
same type.
rdma statistic qp set link mlx5_2/1 auto off
Turn-off auto mode on device mlx5_2 port 1. The allocated
counters can be manually accessed.
rdma statistic qp bind link mlx5_2/1 lqpn 178
On device mlx5_2 port 1, allocate a counter and bind the
specified qp on it
rdma statistic qp unbind link mlx5_2/1 cntn 4 lqpn 178
On device mlx5_2 port 1, bind the specified qp on the
specified counter
rdma statistic qp unbind link mlx5_2/1 cntn 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.
rdma statistic show mr
List all currently allocated MR's and their counters.
rdma statistic show mr mrn 6
Dump a specific MR statistics with mrn 6. Dumps nothing if
does not exists.
