iDRAC 8 nagios plugin

Hi,

We are running a few new PowerEdge servers (13th generation) with iDRAC 8 and we would like to monitor them with our existing Nagios environment.

I was looking at this plugin  but the instructions state it's for firmware 2.15.10.10 - 2.20.20.20;  however they servers are shipping with 2.40.40.40.  Does anyone know if this plugin will still work or if there's a fewer one?

Thank you,

Steven
