I setup Netdata on my server. Now I can monitor all sensors and notifications. Also if you use IMPI you can see the power, current, fans RPM, etc.
I have see that you can send curl commands to the idrac to set fan speeds and also power down or cycle the server remotely.
Here’s a link on how to adjust the fans: https://www.spxlabs.com/blog/2019/3/16/silence-your-dell-poweredge-server
Just playing around and adding more each day.
