Distribution: official part of Check_MK

Supported Agents: SNMP

This Check queries the CPU utilization for various switches made by 3Com and H3C, either standalone or that of the CPUs of all units in the stack. By default it will handle 3com Superstack 4 switches, but it should work with all devices defined in the "Lsw" lanswitch Mibs.

Please note: 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. The CPU usage ratio returned by the check is the average load of the last 60 seconds.

Check parameters

Parameter	Type	Description
warning	int	the percentage of 1-minute average load at which the switch is considered too busy.
critical	int	the percentage of 1-minute average load at which the switch is considered overloaded.

Performance data

None.

Inventory

The check will add one service per Unit/CPU in a stack.

Configuration variables

Variable	Type	Description
superstack4_cpu_default_levels	int, int	the warn and critical levels for the checkl. They are set to default to 50% for "WARN" and 75% for "CRIT".
item:		The CPU found by inventory (it's OID is a multiple of 65536 and will be divided to come to a sane value)
perfdata:		It does not generate any performance data yet.
