    IPMI discovery and direct sensor reading not working

    Hi,

    I have an appliance that I would like to monitor via its IPMI interface. This appliance is running OpenBMC Linux firmware.
    I have successfully added the host, set up IPMI authentication (Auth algorithm: RMPC+ , Privilege: Admin) the interface is up,
    I have added the official template so the automatic discovery of sensors can happen but it returns an empty list. I have manually
    added a few items (sensors) which I know for sure they exist, but zabbix says 'sensor or control does not exist'.
    I have tried to prefix them like "id:" and "name:" but they made no difference. I also tried suffixing the sensors IDs with 0 as some of the OpenIPMI implementations differ but that made no change either.

    If I manually run "ipmitool sensor" command on the Zabbix proxy (from where this host is monitored) it returns all the sensors correctly. If I run "ipmitool sensor powersupply0" or "ipmitool sensor fan0_0" they return correct answer.

    I am a bit puzzled at this stage and trying to understand what is failing and why.

    Thanks!
