ipmi

Distribution: official part of Check_MK

Supported Agents: Linux

This check makes use of the output of a working ipmitool on a Linux system. If the kernel properly supports IPMI and ipmitool is installed, then the agent will output the current state of power supplies, cooling devices, temperatures and other devices avaiable via IPMI. This check makes sure that all those devices are working properly.

Fortunately, IPMI provides not only the current sensor values but also their state, so no levels need to be configured for this checks.

This check provides a summarized mode, where all sensors appear as one summary check per host and a detailed mode with one check per sensor.

Please note: on some systems IPMI reports sensors in a non-ok state wheras actually no problem exists. As of version 1.1.11i1 these sensors can be ignored with the configuration variable ipmi_ignored_sensors.

Item

"Summary" for summary mode, the name of the IPMI item in detailed mode.

Check parameters

None.

Performance data

In summary mode only the current ambient temperature will be output - if available. In detailed mode each sensors outputs its current value.

Inventory

In summary mode, one check is created if at least one sensor is found by the agent. In detailed mode one item is created for each sensor found.

Note: Some obscure hardware lists sensors in the state nr which do not produce usable output. If you set impi_ignore_nr to True then these sensors will be ignored.

Configuration variables

Variable	Type	Description
ipmi_ignore_nr	boolean	If set to True, sensors with the state nr will be ignored. Default is False.
ipmi_summarize	boolean	If set to False, the inventory will create a separate service for each IPMI device. Default is True.
ipmi_ignored_sensors	list	A list of sensors names that should be ignored when doing inventory (for non-summarized mode) or during check for summarized mode). The check does a prefix match on the names.

Examples

# Ignore sensors in state 'nr'
ipmi_ignore_nr = True

# Make inventory produce detailed IPMI checks
ipmi_summarize = False

# Ignore certain types of sensors
ipmi_ignored_sensors = [ "Power_Meter", "Virtual_Fan" ]
