NAME top

       perfquery - query InfiniBand port counters on a single port

SYNOPSIS top

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

DESCRIPTION top

       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 top

-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:
/ssd11/FOSS/rdma-core/build/etc/infiniband-diags/ibdiag.conf
