DESCRIPTION

35   rdma statistic [object] show - Queries the specified RDMA device for RDMA
36       and driver-specific statistics. Show the default hw counters if object
37       is not specified
38       DEV - specifies counters on this RDMA device to show.
39
40       PORT_INDEX - specifies counters on this RDMA port to show.
41
42
43   rdma statistic <object> set - configure counter statistic auto-mode for a
44       specific device/port
45       In auto mode all objects belong to one category are bind automatically
46       to a single counter set.
47
48
49   rdma statistic <object> bind - manually bind an object (e.g., a qp) with a
50       counter
51       When bound the statistics of this object are available in this counter.
52
53
54   rdma statistic <object> unbind - manually unbind an object (e.g., a qp)
55       from the counter previously bound
56       When unbound the statistics of this object are no longer available in
57       this counter; And if object id is not specified then all objects on
58       this counter will be unbound.
59
60       COUNTER-ID - specifies the id of the counter to be bound.  If this
61       argument is omitted then a new counter will be allocated.

EXAMPLES

65       rdma statistic show
66           Shows the state of the default counter of all RDMA devices on the
67           system.
68
69       rdma statistic show link mlx5_2/1
70           Shows the state of the default counter of specified RDMA port
71
72       rdma statistic qp show
73           Shows the state of all qp counters of all RDMA devices on the sys‐
74           tem.
75
76       rdma statistic qp show link mlx5_2/1
77           Shows the state of all qp counters of specified RDMA port.
78
79       rdma statistic qp show link mlx5_2 pid 30489
80           Shows the state of all qp counters of specified RDMA port and
81           belonging to pid 30489
82
83       rdma statistic qp mode
84           List current counter mode on all devices
85
86       rdma statistic qp mode link mlx5_2/1
87           List current counter mode of device mlx5_2 port 1
88
89       rdma statistic qp set link mlx5_2/1 auto type on
90           On device mlx5_2 port 1, for each new QP bind it with a counter
91           automatically. Per counter for QPs with same qp type in each
92           process. Currently only "type" is supported.
93
94       rdma statistic qp set link mlx5_2/1 auto off
95           Turn-off auto mode on device mlx5_2 port 1. The allocated counters
96           can be manually accessed.
97
98       rdma statistic qp bind link mlx5_2/1 lqpn 178
99           On device mlx5_2 port 1, allocate a counter and bind the specified
100           qp on it
101
102       rdma statistic qp unbind link mlx5_2/1 cntn 4 lqpn 178
103           On device mlx5_2 port 1, bind the specified qp on the specified
104           counter
105
106       rdma statistic qp unbind link mlx5_2/1 cntn 4
107           On device mlx5_2 port 1, unbind all QPs on the specified counter.
108           After that this counter will be released automatically by the ker‐
109           nel.
