Alert on CPU delta between two devices?

sbrooke

Tried searching and didn't have any luck. I'm trying to find a way to generate an alert based on the CPU delta of two servers that are in a cluster. If the CPU delta exceeds 15% I want to fire the alert. The idea is get alerted if the cluster becomes imbalanced. Anyone have a pointer for me?

Unfortunately I don't know of a good way to do this. I vaguely recall other threads attempting to do similar things but to no avail.

I personally think that having the ability to alert on a delta would be a really awesome feature, one that would set Orion apart from a lot of other products in this space.

If I get a chance I will look and log a feature request if one doesn't already exist for this.

In case it's not clear, this is an active/active cluster, not active/standby. The CPU util should be roughly equal at all times. If one server starts taking more load it's a sign that something's wrong.

No ideas? I've been poking around some more in Advanced Alerts and it's not looking encouraging.

Thanks Byron! I was afraid that might be the case.
