Dell Fibre Channel Switches: Port Status
|Distribution:||official part of Check_MK|
This checks monitors fibre channel ports of devices supporting the fibre
channel management (FCMGMT) MIB, notably Dell fibre channel switches.
Monitored are the physical, operational, or adminstrative state of the ports,
the number of received and transmitted objects (RxObjects, TxObjects),
the incoming and outgoing throughput derived from the number of received
and transmitted elements (RxElements, TxElements), and the following
error counters: CRC errors, Enc-OUT frames, no Tx credits, C3 discards.
The check has a non-OK state in the following situations:
 The physical, operational, or adminstrative state of the port is not
 The current or averaged throughput exceeds the configured absolute or
 One of the error counters exceeds its configured levels.
Averaging: This check supports averaging on all counters. Averaging is
turned on but setting the check parameter "average" to a number of minutes.
In this 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!). If configured, port names of the device will be part
of the check item (and thus the service description).
One service is created for all operational ports
if the administrativ state is not 1 (unknown) or 3 (offline).
It can be configured (see CONFIGURATION VARIABLES)
how operational ports are defined.
