3COM and H3C switches: CPU utilization
|Distribution:||official part of Check_MK|
This Check queries the CPU utilization of various LAN switches that are
supporting the MIB for H3C lan switches. These are: newer 3COM switches
(Superstack 4 and later), H3C branded switches and now for example the HP
"A-Series" Networking gear. The same switches from the original maker Huawei
are not supporting the MIB. The check tries to correctly label the CPU in
your switch / stack / core switch module slots.
The check goes WARN/CRIT if the average CPU usage of the last five minutes
exceeds configurable levels.
Note that some of these switches don't handle SNMP well and might generate
up to 90% cpu load while queried. To accomodate for this you should lower
the frequency of SNMP based checks with them.
Some devices have a high usage even in normal conditions (i.e. running full
BGP tables). In that case you might have to fine tune the check parameters
or even have to disable the check.
A string describing the switch and unit number, for example "Switch 2 CPU 0"
or "Switch 1 Slot 11".
The check will create one separate service per CPU.
