Idrac virtual Disk offline rule help?

Hey everyone, I would like to create an alert rule to tell me if any of the virtual disks go offline on our R720 servers. I’m not sure how to begin with this specifically as to figure out what value i need to pull. I get that I’d look at device.hostname like Idrac, after that there is some sensor(?) like Virtual Disk, then that value would equal offline? errored? any help is appreciated

What have you tried? Also have you looked in the alerts rules collection I think we may have one already.

I have not tried anything as of yet as I really wasnt sure how to go about it. I also didnt know that the alert rule collection existed…where is that??

Edit: How did I never notice this button before!? Yup its right there. Thank you!
