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

Files

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.

Examples

perfquery                # read local port performance counters
perfquery 32 1           # read performance counters from lid 32, port 1
perfquery -x 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 -x -r 32 1     # read extended performance counters and reset
perfquery -R 0x20 1      # reset performance counters of port 1 only
perfquery -x -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
