NAME

       perfquery - query InfiniBand port counters on a single port

SYNOPSIS

       perfquery [options] [<lid|guid> [[port(s)] [reset_mask]]]

DESCRIPTION

       perfquery  uses  PerfMgt  GMPs  to  obtain  the  PortCounters  (basic  performance  and  error counters),
       PortExtendedCounters,   PortXmitDataSL,   PortRcvDataSL,   PortRcvErrorDetails,   PortXmitDiscardDetails,
       PortExtendedSpeedsCounters,  or  PortSamplesControl  from  the PMA at the node/port specified. Optionally
       shows aggregated counters for all ports of node.  Finally it can, reset after read,  or  just  reset  the
       counters.

       Note: In PortCounters, PortCountersExtended, PortXmitDataSL, and PortRcvDataSL, 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.

       Note: For PortCounters, ExtendedCounters, and resets, multiple ports can be specified by either  a  comma
       separated list or a port range.  See examples below.

OPTIONS

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

       -X, --xmtsl
              show transmit data SL counter. This is an optional counter for QoS.

       -S, --rcvsl
              show receive data SL counter. This is an optional counter for QoS.

       -D, --xmtdisc
              show transmit discard details. This is an optional counter.

       -E, --rcverr
              show receive error details. This is an optional counter.

       -D, --xmtdisc
              show transmit discard details. This is an optional counter.

       -T, --extended_speeds
              show extended speeds port counters. This is an optional counter.

       --oprcvcounters
              show Rcv Counters per Op code. This is an optional counter.

       --flowctlcounters
              show flow control counters. This is an optional counter.

       --vloppackets
              show packets received per Op code per VL. This is an optional counter.

       --vlopdata
              show data received per Op code per VL. This is an optional counter.

       --vlxmitflowctlerrors
              show flow control update errors per VL. This is an optional counter.

       --vlxmitcounters
              show ticks waiting to transmit counters per VL. This is an optional counter.

       --swportvlcong
              show sw port VL congestion. This is an optional counter.

       --rcvcc
              show Rcv congestion control counters. This is an optional counter.

       --slrcvfecn
              show SL Rcv FECN counters. This is an optional counter.

       --slrcvbecn
              show SL Rcv BECN counters. This is an optional counter.

       --xmitcc
              show Xmit congestion control counters. This is an optional counter.

       --vlxmittimecc
              show VL Xmit Time congestion control counters. This is an optional counter.

       -c, --smplctl
              show port samples control.

       -a, --all_ports
              show aggregated counters for all ports of the destination lid, reset all counters for  all  ports,
              or  if  multiple  ports  are  specified,  aggregate  the  counters of the specified 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) or multiple ports
              are specified iterate through each port rather than doing than aggregate operation.

       -r, --reset_after_read
              reset counters after read

       -R, --Reset_only
              only reset counters

   Addressing Flags
       -G, --Guid     The address specified is a Port GUID

       -L, --Lid   The address specified is a LID

       -s, --sm_port <smlid>     use 'smlid' as the target lid for SA queries.

   Port Selection flags
       -C, --Ca <ca_name>    use the specified ca_name.

       -P, --Port <ca_port>    use the specified ca_port.

   Local port Selection
       Multiple port/Multiple CA support: when  no  IB  device  or  port  is  specified  (see  the  "local  umad
       parameters" below), the libibumad library selects the port to use 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 libibumad library attempts to fulfill the user request, and
          will fail if it is not possible.

          For example:

              ibaddr                 # use the first port (criteria #1 above)
              ibaddr -C mthca1       # pick the best port from "mthca1" only.
              ibaddr -P 2            # use the second (active/up) port from the first available IB device.
              ibaddr -C mthca0 -P 2  # use the specified port only.

   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, --help      show the usage message

       -v, --verbose
              increase the application verbosity level.  May be used several times (-vv or -v -v -v)

       -V, --version     show the version info.

   Configuration flags
       -t, --timeout <timeout_ms> override the default timeout for the solicited mads.

       -y, --m_key <key>
              use the specified M_key for requests. If non-numeric value (like 'x') is specified  then  a  value
              will be prompted for.

       --config, -z  <config_file> Specify alternate config file.
          Default: /etc/infiniband-diags/ibdiag.conf
