Hi,
We have the same issue as thousands of LibreNMS users. All other tools Zabbix, Nagios etc support IPMI Monitoring AND snmp monitoring however LibreNMS only supports snmp and optionally, if snmp works well, you might get some IPMI data unless you have a newer IPMI chip like ILO4. It is strange you can’t just add IPMI without snmp. As this is so many times requested I wonder why no one ever created an update for this. I will try your hack tomorrow as we have like 300 of servers in LibreNMS on IPMI and we only pull snmp data from our own, non dedicated servers, which are like 20.
Of the 300 machines, maybe 30 have ILO3, SuperMicro X8/X9 mainboard and cannot be added on snmp as there is no snmp agent in the IPMI chip.
