NAME

       rdma-statistic - RDMA statistic counter configuration

SYNOPSIS

       rdma [ OPTIONS ] statistic  { COMMAND | help }

       rdma statistic { OBJECT } show

       rdma statistic [ OBJECT ] show link [ DEV/PORT_INDX ]

       rdma statistic OBJECT mode

       rdma statistic OBJECT set COUNTER_SCOPE [ DEV/PORT_INDEX] auto { CRITERIA | off }

       rdma statistic OBJECT bind COUNTER_SCOPE [ DEV/PORT_INDEX] [ OBJECT-ID ] [ COUNTER-ID ]

       rdma statistic OBJECT unbind COUNTER_SCOPE [ DEV/PORT_INDEX] [ COUNTER-ID ] [ OBJECT-ID ]

       COUNTER_SCOPE := { link | dev }

       OBJECT := { qp | mr }

       CRITERIA := { type }

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.

   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. 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.

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 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 QP bind it with a counter automatically. Per
           counter for QPs with same qp type in each process. Currently only "type" is supported.

       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.
