Alert template for average CPU usage

I have an Alert Rule for average CPU usage over 90%, which is working for multicore servers (thanks to slashdoom in another thread). I’m struggling to get an Alert Template to give the CPU aggregate of all cores though. The alert template returns (multiple) per core %, using this: {{ $value[‘processor_usage’] }} Which isn’t what I’m looking for.

Anyone have this working?

Thanks,
Joel

Post your rule so we can see what the output will look like
