PERFQUERY(8) OpenIB Diagnostics PERFQUERY(8)NAMEperfquery - query InfiniBand port counters
SYNOPSISperfquery [-d(ebug)] [-G(uid)] [-a(ll_ports)] [-r(eset_after_read)]
[-R(eset_only)] [-C ca_name] [-P ca_port] [-t(imeout) timeout_ms]
[-V(ersion)] [-h(elp)] [<lid|guid> [[port] [reset_mask]]]
DESCRIPTIONperfquery uses PerfMgt GMPs to obtain the PortCounters (basic perfor‐
mance and error counters) from the PMA at the node specified. Option‐
ally reset all or
OPTIONS-a, --all_ports
show aggregated counters for all ports of the destination lid
-r, --reset_after_read
reset counters after read
-R, --Reset_only
only reset counters
COMMON OPTIONS
Most OpenIB diagnostics take the following common flags. The exact list
of supported flags per utility can be found in the usage message and
can be shown using the util_name -h syntax.
# Debugging flags
-d raise the IB debugging level.
May be used several times (-ddd or -d -d -d).
-e show send and receive errors (timeouts and others)
-h show the usage message
-v increase the application verbosity level.
May be used several times (-vv or -v -v -v)
-V show the version info.
# Addressing flags
-D use directed path address arguments. The path
is a comma separated list of out ports.
Examples:
"0" # self port
"0,1,2,1,4" # out via port 1, then 2, ...
-G use GUID address argument. In most cases, it is the Port GUID.
Example:
"0x08f1040023"
-s <smlid> use 'smlid' as the target lid for SM/SA queries.
# Other common flags:
-C <ca_name> use the specified ca_name.
-P <ca_port> use the specified ca_port.
-t <timeout_ms> override the default timeout for the solicited mads.
Multiple CA/Multiple Port Support
When no IB device or port is specified, the port to use is selected by
the following criteria:
1. the first port that is ACTIVE.
2. if not found, the first port that is UP (physical link up).
If a port and/or CA name is specified, the user request is attempted to
be fulfilled, and will fail if it is not possible.
EXAMPLESperfquery # read local port performance counters
perfquery 32 1 # read performance counters from lid 32, port 1
perfquery-a 32 # read performance counters from lid 32, all
ports
perfquery-r 32 1 # read performance counters and reset
perfquery-R 0x20 1 # reset performance counters of port 1 only
perfquery-R -a 32 # reset performance counters of all ports
perfquery-R 32 2 0x0fff # reset only error counters of port 2
perfquery-R 32 2 0xf000 # reset only non-error counters of port 2
