Privileges

If you are running the exporter as unprivileged user, but need to execute the FreeIPMI tools as root (as is likely necessary to access the local IPMI interface), you can do the following:

NOTE: Make sure to adapt all absolute paths to match your distro!

1. Add sudoers files to permit the following commands

   ipmi-exporter ALL = NOPASSWD: /usr/sbin/ipmimonitoring,\
                                 /usr/sbin/ipmi-sensors,\
                                 /usr/sbin/ipmi-dcmi,\
                                 /usr/sbin/ipmi-raw,\
                                 /usr/sbin/bmc-info,\
                                 /usr/sbin/ipmi-chassis,\
                                 /usr/sbin/ipmi-sel
   

2. In your module config, override the collector command with sudo for every collector you are using and add the actual command as custom argument. Example for the "ipmi" collector:

   collector_cmd:
     ipmi: /usr/bin/sudo
   custom_args:
     ipmi:
     - "/usr/sbin/ipmimonitoring"
   

   See also the sudo example config.

Note that no elevated privileges are necessary for getting remote metrics.
