perfquery
Command
The
perfquery
command is useful for find errors on a particular or number of
HCA’s and switch ports. You can also use
perfquery
to reset HCA and switch port
counters.
To see a usage statement for the
perfquery
command, perform the following:
r01lead:/opt/sgi/sbin # perfquery --help
Usage: perfquery [-d(ebug) -G(uid) -a(ll_ports) -r(eset_after_read) -C ca_name -P ca_port -R(eset_only)
-t(imeout) timeout_ms -V(ersion) -h(elp)] [<lid|guid> [[port] [reset_mask]]]
Examples:
perfquery # read local port’s performance counters
perfquery 32 1 # read performance counters from lid 32, port 1
perfquery -e 32 1 # read extended 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 -e -r 32 1 # read extended performance counters and reset
perfquery -R 0x20 1 # reset performance counters of port 1 only
perfquery -e -R 0x20 1 # reset extended 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
