.SH SYNOPSIS

.sp

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

.SH DESCRIPTION

.sp

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.

.sp

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.

.sp

Note: Inputting a port of 255 indicates an operation be performed on all ports.

.sp

Note: For PortCounters, ExtendedCounters, and resets, multiple ports can be

specified by either a comma separated list or a port range.  See examples below.

.SH OPTIONS

.INDENT 0.0

.TP

.B \fB\-x, \-\-extended\fP

show extended port counters rather than (basic) port counters.

Note that extended port counters attribute is optional.

.TP

.B \fB\-X, \-\-xmtsl\fP

show transmit data SL counter. This is an optional counter for QoS.

.TP

.B \fB\-S, \-\-rcvsl\fP

show receive data SL counter. This is an optional counter for QoS.

.TP

.B \fB\-D, \-\-xmtdisc\fP

show transmit discard details. This is an optional counter.

.TP

.B \fB\-E, \-\-rcverr\fP

show receive error details. This is an optional counter.

.TP

.B \fB\-D, \-\-xmtdisc\fP

show transmit discard details. This is an optional counter.

.TP

.B \fB\-T, \-\-extended_speeds\fP

show extended speeds port counters. This is an optional counter.

.TP

.B \fB\-\-oprcvcounters\fP

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

.TP

.B \fB\-\-flowctlcounters\fP

show flow control counters. This is an optional counter.

.TP

.B \fB\-\-vloppackets\fP

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

.TP

.B \fB\-\-vlopdata\fP

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

.TP

.B \fB\-\-vlxmitflowctlerrors\fP

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

.TP

.B \fB\-\-vlxmitcounters\fP

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

.TP

.B \fB\-\-swportvlcong\fP

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

.TP

.B \fB\-\-rcvcc\fP

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

.TP

.B \fB\-\-slrcvfecn\fP

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

.TP

.B \fB\-\-slrcvbecn\fP

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

.TP

.B \fB\-\-xmitcc\fP

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

.TP

.B \fB\-\-vlxmittimecc\fP

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

.TP

.B \fB\-c, \-\-smplctl\fP

show port samples control.

.TP

.B \fB\-a, \-\-all_ports\fP

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.

.TP

.B \fB\-l, \-\-loop_ports\fP

If all ports are selected by the user (either through the \fB\-a\fP option

or port 255) or multiple ports are specified iterate through each port rather

than doing than aggregate operation.

.TP

.B \fB\-r, \-\-reset_after_read\fP

reset counters after read

.TP

.B \fB\-R, \-\-Reset_only\fP

only reset counters

.SS Addressing Flags

.\" Define the common option -G

.

.sp

\fB\-G, \-\-Guid\fP     The address specified is a Port GUID

.\" Define the common option -L

.

.sp

\fB\-L, \-\-Lid\fP   The address specified is a LID

.\" Define the common option -s

.

.sp

\fB\-s, \-\-sm_port <smlid>\fP     use \(aqsmlid\(aq as the target lid for SA queries.

.SS Port Selection flags

.\" Define the common option -C

.

.sp

\fB\-C, \-\-Ca <ca_name>\fP    use the specified ca_name.

.\" Define the common option -P

.

.sp

\fB\-P, \-\-Port <ca_port>\fP    use the specified ca_port.

.\" Explanation of local port selection

.

.SS Local port Selection

.sp

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:

.INDENT 0.0

.INDENT 3.5

.INDENT 0.0

.IP 1. 3

the first port that is ACTIVE.

.IP 2. 3

if not found, the first port that is UP (physical link up).

.UNINDENT

.sp

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.

.sp

For example:

.INDENT 0.0

.INDENT 3.5

.sp

.nf

.ft C

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.
