Brocade FibreChannel Switches: FibreChannel Ports
|Distribution:||official part of Check_MK|
This checks monitors a FibreChannel port of a Brocade FC switch
in great detail. It obsoletes the older checks fc_brocade_port and
fc_brocade_port_detailed. The check goes critical under the following conditions:
 The physical state, operational state or adminstrative state of the port is not
 The current or averaged throughput exceeds certain absolute or
 An error counter exceeds its configured levels (CRC errors, Enc-OUT
Enc-IN, frames, no Tx credits, C3 discards)
Averaging: This check supports averaging on all counters. Averaging is
turned on but setting the check parameter "average" to a number of minutes.
In that case the check produces additional performance data for each parameter
and all warning/error levels are only applied on the averaged value, not on
the current one. This is especially helpful when using levels on the throughput.
Note: The counters CRC errors and Enc-OUT are represented as percentages in
relation to the number of received frames. C3 discards and no Tx credits are
in relation to the number of sent frames.
The item is the port-number as two-digit or three-digit string (on switches
with 100 or more ports) as printed on the switch (note: the SNMP-index of
port 00 is 1!). For ISL ports (inter-switch-links), an ISL is appended
to the item, e.g. 00 ISL. This allows you to create rules which select
different check parameters for ISL and normal ports without specifying each
individual port. Also, if you have configured port names, they will appear
in the check item (and thus the service description). This can be turned
One service is created for each operational port. What this exactly means
can be configured (see CONFIGURATION VARIABLES).
