Understanding Service Procedures
To help ascertain the health of a node, the perfquery command displays the performance, error, and data counters for that node.
On the management controller, type:
# perfquery lid port
where:
lid is the LID of the node.
port is the port of the node.
Note - If a port value of 255 is specified for a switch node, the counters are the total for all switch ports.
For example:
# perfquery 24 8 # Port counters: Lid 24 port 8 PortSelect:......................8 CounterSelect:...................0x1b01 SymbolErrors:....................0 . . . VL15Dropped:.....................0 XmtData:.........................2925432 RcvData:.........................2966688 XmtPkts:.........................40631 RcvPkts:.........................41204 #
Note - The output in the example is just a portion of the full output.
