3Com and H3C Switches: Fan and Power Supply
Distribution official part of Check_MK
License GPLv2
Supported Agents SNMP
This check queries the fan and power supply sensors of various switches made by 3Com and H3C. By default it will handle 3com Superstack 4 switches, but it should work with all devices defined in the "Lsw" lanswitch Mibs.

This check returns:

OK if the active state is reported for the sensor.

WARN if the not-install or unsupport state is reported for the sensor.

CRIT if the deactive state is reported for the sensor.

UNKNOWN if the queried sensor is not found.

Please note: some of these switches don't handle SNMP well and might generate up to 90% CPU load while queried. To accommodate for this you should lower the frequency of SNMP based checks with them.
