NAME

       perfquery - query InfiniBand port counters

SYNOPSIS

       perfquery    [-d(ebug)]    [-G(uid)]    [-e(xtended)]    [-a(ll_ports)]    [-l(oop_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]]]

DESCRIPTION

       perfquery  uses  PerfMgt  GMPs  to  obtain  the  PortCounters (basic performance and error
       counters) or PortExtendedCounters from the PMA  at  the  node/port  specified.  Optionally
       shows  aggregated  counters for all ports of node.  Also, optionally, reset after read, or
       only reset counters.

       Note: In both PortCounters and PortCountersExtended, components that represent Data  (e.g.
       PortXmitData and PortRcvData) indicate octets divided by 4 rather than just octets.

       Note: Inputting a port of 255 indicates an operation be performed on all ports.

OPTIONS

       -e, --extended
              show  extended port counters rather than (basic) port counters.  Note that extended
              port counters attribute is optional.

       -a, --all_ports
              show aggregated counters for all ports of the destination lid or reset all counters
              for all ports.  If the destination lid does not support the AllPortSelect flag, all
              ports will be iterated through to emulate AllPortSelect behavior.

       -l, --loop_ports
              If all ports are selected by the user (either through the -a option  or  port  255)
              iterate through each port rather than doing than aggregate operation.

       -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

       -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.

EXAMPLES

       perfquery               # read local port 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 perf 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
