DESCRIPTION <\/a> <\/h2>\n

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<\/b>
DEV<\/i> – specifies counters on this RDMA device to show.<\/p>\n

PORT_INDEX<\/i> – specifies counters on this RDMA port to show.<\/p>\n

FILTER_NAME<\/i> – specifies a filter to show only the results matching it.<\/p>\n

rdma statistic set – configure counter statistic auto-mode for a specific device\/port<\/b>
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\u2019s.<\/p>\n

rdma statistic bind – manually bind an object (e.g., a qp) with a counter<\/b>
When bound the statistics of this object are available in this counter. Not applicable for MR\u2019s.<\/p>\n

rdma statistic unbind – manually unbind an object (e.g., a qp) from the counter previously bound<\/b>
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\u2019s.<\/p>\n

COUNTER-ID<\/i> – specifies the id of the counter to be bound. If this argument is omitted then a new counter will be allocated.<\/p>\n

EXAMPLES <\/a> <\/h2>\n

rdma statistic show<\/p>\n

Shows the state of the default counter of all RDMA devices on the system.<\/p>\n

rdma statistic show link mlx5_2\/1<\/p>\n

Shows the state of the default counter of specified RDMA port<\/p>\n

rdma statistic qp show<\/p>\n

Shows the state of all qp counters of all RDMA devices on the system.<\/p>\n

rdma statistic qp show link mlx5_2\/1<\/p>\n

Shows the state of all qp counters of specified RDMA port.<\/p>\n

rdma statistic qp show link mlx5_2 pid 30489<\/p>\n

Shows the state of all qp counters of specified RDMA port and belonging to pid 30489<\/p>\n

rdma statistic qp show link mlx5_2 qp-type UD<\/p>\n

Shows the state of all qp counters of specified RDMA port and with QP type UD<\/p>\n

rdma statistic qp mode<\/p>\n

List current counter mode on all devices<\/p>\n

rdma statistic qp mode link mlx5_2\/1<\/p>\n

List current counter mode of device mlx5_2 port 1<\/p>\n

rdma statistic qp set link mlx5_2\/1 auto type on<\/p>\n

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.<\/p>\n

rdma statistic qp set link mlx5_2\/1 auto pid on<\/p>\n

On device mlx5_2 port 1, for each new user QP bind it with a counter automatically. Per counter for QPs with same pid.<\/p>\n

rdma statistic qp set link mlx5_2\/1 auto pid,type on<\/p>\n

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.<\/p>\n

rdma statistic qp set link mlx5_2\/1 auto off<\/p>\n

Turn-off auto mode on device mlx5_2 port 1. The allocated counters can be manually accessed.<\/p>\n

rdma statistic qp bind link mlx5_2\/1 lqpn 178<\/p>\n

On device mlx5_2 port 1, allocate a counter and bind the specified qp on it<\/p>\n

rdma statistic qp unbind link mlx5_2\/1 cntn 4 lqpn 178<\/p>\n

On device mlx5_2 port 1, bind the specified qp on the specified counter<\/p>\n

rdma statistic qp unbind link mlx5_2\/1 cntn 4<\/p>\n

On device mlx5_2 port 1, unbind all QPs on the specified counter. After that this counter will be released automatically by the kernel.<\/p>\n

rdma statistic show mr<\/p>\n

List all currently allocated MR\u2019s and their counters.<\/p>\n

rdma statistic show mr mrn 6<\/p>\n

Dump a specific MR statistics with mrn 6. Dumps nothing if does not exists.<\/p>\n
