Need help with ILO4

I would love to make this work on our iLO4 servers, has anyone been able to get it working?

I downloaded the latest version via the review by: “Link to Version 1.55 / ILO4
bypeetsche, March 8, 2013” but when I run the command I only end up with [CHECK_ILO2_HEALTH UNKNOWN – plugin timed out (timeout 15s)]. I followed the instructions to install it and already had the 3 modules installed and can reach the management interface via https. I get the same output whether I try it on the commandline as root or via Nagios interface as nagios user.

Any response would be helpful.
