3COM and H3C switches: Fan and Power Supply

Distribution: official part of Check_MK
License: GPL
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 accomodate for this you should lower the frequency of SNMP based checks with them.

Item

The fan or powersupply sensor found by inventory (it's OID is a multiple of 65536 and will be divided to come to a sane value)

Discovery

The check will add one service per sensor.
