Setting CPU Utilization Alert Threshold as Percentage in Grafana Prometheus

Grafana Prometheus
1

Hello Community,

I am currently using Prometheus with Grafana and I need to create an alert for CPU utilization. The threshold for this alert should be set at 90%.

In the Threshold section of Grafana, I’ve entered “90”, but I am unsure if this value is treated as a percentage or as an absolute number. I want the alert to trigger when the CPU utilization exceeds 90% of its capacity.

Here is a screenshot of my current settings:

Could anyone please confirm if the threshold value I’ve set is treated as a percentage? If not, could you guide me on how to set the threshold as a percentage?

Any advice or guidance would be greatly appreciated.

1.) That A query is not a query for CPU utilization. Maybe you can use Awesome Prometheus alerts | Collection of alerting rules

2.) You don’t need B reduce, because A is instant type, so it is already reduces
