Problems with IPMI

Troubleshooting
1

NOTE: I put in REDACTED for all hostname/IP/passwords and it looks like all that got stripped out.

I enabled the IPMI rule and get the following error

OMD[ZHV_checkmk]:~$ /omd/sites/ZHV_checkmk/share/check_mk/agents/special/agent_ipmi_sensors -u ‘IPMIread’ -p ‘’ -l ‘user’ --ipmi-command freeipmi ‘’
<<<ipmi_sensors:sep(124)>>>
Traceback (most recent call last):

Command came from debug cmk
OMD[ZHV_checkmk]:~$ cmk --debug -vvI

Package freeipmi is a prerequisite package. Installed, set type to LAN_2_0 and it works great.

Please start your special agent with the “–debug” switch. It is possible to get a little bit better error message.
This message says only that the error message is no valid error message :slight_smile:
