.. perfquery [options] [<lid|guid> [[port(s)] [reset_mask]]] 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. NDENT 0.0

-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

--dgid <gid> destination GID: use when GRH is required in packets (IPv6 format) NINDENT

Define the common option -G
. -G, --Guid The address specified is a Port GUID Define the common option -L
. -L, --Lid The address specified is a LID Define the common option -s
. -s, --sm_port <smlid> use \(aqsmlid\(aq as the target lid for SA queries. Define the common option -C
. -C, --Ca <ca_name> use the specified ca_name. Define the common option -P
. -P, --Port <ca_port> use the specified ca_port. Explanation of 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: NDENT 0.0 NDENT 3.5 NDENT 0.0 the first port that is ACTIVE. if not found, the first port that is UP (physical link up). NINDENT 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: NDENT 0.0 NDENT 3.5

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.

NINDENT NINDENT NINDENT NINDENT Define the common option -d
. NDENT 0.0

-d raise the IB debugging level. May be used several times (-ddd or -d -d -d). NINDENT Define the common option -e

-e show send and receive errors (timeouts and others) NINDENT Define the common option -h
. -h, --help show the usage message Define the common option -v

-v, --verbose increase the application verbosity level. May be used several times (-vv or -v -v -v) NINDENT Define the common option -V
. -V, --version show the version info.

Define the common option -t
. -t, --timeout <timeout_ms> override the default timeout for the solicited mads. Define the common option -y
. NDENT 0.0

-y, --m_key <key> use the specified M_key for requests. If non-numeric value (like \(aqx\(aq) is specified then a value will be prompted for. NINDENT Define the common option -z
. --config, -z <config_file> Specify alternate config file. NDENT 0.0 NDENT 3.5 Default: /etc/infiniband-diags/ibdiag.conf NINDENT NINDENT

Common text for the config file
. /etc/infiniband-diags/ibdiag.conf A global config file is provided to set some of the common options for all tools. See supplied config file for details. NDENT 0.0 NDENT 3.5
