DESCRIPTIONperfquery uses PerfMgt GMPs to obtain the PortCounters (basic perfor‐
mance and error counters), PortExtendedCounters, PortXmitDataSL, PortR‐
cvDataSL, PortRcvErrorDetails, PortXmitDiscardDetails, PortExtended‐
SpeedsCounters, or PortSamplesControl 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 PortCounters, PortCountersExtended, PortXmitDataSL, and PortR‐
cvDataSL, components that represent Data (e.g. PortXmitData and PortR‐
cvData) indicate octets divided by 4 rather than just octets.
Note: Inputting a port of 255 indicates an operation be performed on
all ports.
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 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.
EXAMPLESperfquery # 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
