6 perfquery - query InfiniBand port counters on a single port
7
9 perfquery [options] [<lid|guid> [[port(s)] [reset_mask]]]
10
12 perfquery uses PerfMgt GMPs to obtain the PortCounters (basic perfor‐
13 mance and error counters), PortExtendedCounters, PortXmitDataSL, PortR‐
14 cvDataSL, PortRcvErrorDetails, PortXmitDiscardDetails, PortExtended‐
15 SpeedsCounters, or PortSamplesControl from the PMA at the node/port
16 specified. Optionally shows aggregated counters for all ports of node.
17 Finally it can, reset after read, or just reset the counters.
18 Note: In PortCounters, PortCountersExtended, PortXmitDataSL, and PortR‐
20 cvDataSL, components that represent Data (e.g. PortXmitData and PortR‐
21 cvData) indicate octets divided by 4 rather than just octets.
22 Note: Inputting a port of 255 indicates an operation be performed on
24 all ports.
25 Note: For PortCounters, ExtendedCounters, and resets, multiple ports
27 can be specified by either a comma separated list or a port range. See
28 examples below.
29
31 -x, --extended
32 show extended port counters rather than (basic) port counters.
33 Note that extended port counters attribute is optional.
34 -X, --xmtsl
36 show transmit data SL counter. This is an optional counter for
37 QoS.
38 -S, --rcvsl
40 show receive data SL counter. This is an optional counter for
41 QoS.
42 -D, --xmtdisc
44 show transmit discard details. This is an optional counter.
45 -E, --rcverr
47 show receive error details. This is an optional counter.
48 -D, --xmtdisc
50 show transmit discard details. This is an optional counter.
51 -T, --extended_speeds
53 show extended speeds port counters. This is an optional counter.
54 --oprcvcounters
56 show Rcv Counters per Op code. This is an optional counter.
57 --flowctlcounters
59 show flow control counters. This is an optional counter.
60 --vloppackets
62 show packets received per Op code per VL. This is an optional
63 counter.
64 --vlopdata
66 show data received per Op code per VL. This is an optional
67 counter.
68 --vlxmitflowctlerrors
70 show flow control update errors per VL. This is an optional
71 counter.
72 --vlxmitcounters
74 show ticks waiting to transmit counters per VL. This is an
75 optional counter.
76 --swportvlcong
78 show sw port VL congestion. This is an optional counter.
79 --rcvcc
81 show Rcv congestion control counters. This is an optional
82 counter.
83 --slrcvfecn
85 show SL Rcv FECN counters. This is an optional counter.
86 --slrcvbecn
88 show SL Rcv BECN counters. This is an optional counter.
89 --xmitcc
91 show Xmit congestion control counters. This is an optional
92 counter.
93 --vlxmittimecc
95 show VL Xmit Time congestion control counters. This is an
96 optional counter.
97 -c, --smplctl
99 show port samples control.
100 -a, --all_ports
102 show aggregated counters for all ports of the destination lid,
103 reset all counters for all ports, or if multiple ports are spec‐
104 ified, aggregate the counters of the specified ports. If the
105 destination lid does not support the AllPortSelect flag, all
106 ports will be iterated through to emulate AllPortSelect behav‐
107 ior.
108 -l, --loop_ports
110 If all ports are selected by the user (either through the -a
111 option or port 255) or multiple ports are specified iterate
112 through each port rather than doing than aggregate operation.
113 -r, --reset_after_read
115 reset counters after read
116 -R, --Reset_only
118 only reset counters
119 Addressing Flags
121 -G, --Guid The address specified is a Port GUID
122 -L, --Lid The address specified is a LID
124 -s, --sm_port <smlid> use 'smlid' as the target lid for SA queries.
126 Port Selection flags
128 -C, --Ca <ca_name> use the specified ca_name.
129 -P, --Port <ca_port> use the specified ca_port.
131 Local port Selection
133 Multiple port/Multiple CA support: when no IB device or port is speci‐
134 fied (see the "local umad parameters" below), the libibumad library
135 selects the port to use by the following criteria:
136 1. the first port that is ACTIVE.
138 2. if not found, the first port that is UP (physical link up).
140 If a port and/or CA name is specified, the libibumad library
142 attempts to fulfill the user request, and will fail if it is not
143 possible.
144 For example:
146 ibaddr # use the first port (criteria #1 above)
148 ibaddr -C mthca1 # pick the best port from "mthca1" only.
149 ibaddr -P 2 # use the second (active/up) port from the first available IB device.
150 ibaddr -C mthca0 -P 2 # use the specified port only.
151 Debugging flags
153 -d raise the IB debugging level. May be used several times (-ddd
154 or -d -d -d).
155 -e show send and receive errors (timeouts and others)
157 -h, --help show the usage message
159 -v, --verbose
161 increase the application verbosity level. May be used several
162 times (-vv or -v -v -v)
163 -V, --version show the version info.
165 Configuration flags
167 -t, --timeout <timeout_ms> override the default timeout for the
168 solicited mads.
169 -y, --m_key <key>
171 use the specified M_key for requests. If non-numeric value (like
172 'x') is specified then a value will be prompted for.
173 --config, -z <config_file> Specify alternate config file.
175 Default: /etc/infiniband-diags/ibdiag.conf
176
178 CONFIG FILE
179 /etc/infiniband-diags/ibdiag.conf
180 A global config file is provided to set some of the common options for
182 all tools. See supplied config file for details.
