From “cmk --debug -vvI hostname” I could see that the hpe ilo special agent tried to query the host’s IP, not the management board IP. After changing the servers IP to its management board IP the services are successfully discovered.
I’m used to have the server and its management board as one single host in monitoring which shows output of the checkmk agent installed in the servers OS and iLO data together. Isn’t this possible/intended with iLO special agent?
