My PrometheusMeterRegistry returns a very low decimal value for the system_cpu_usage metric (0.004593000743494424). I want to display this value in a Grafana dashboard as a percentage of the overall CPU usage. I can't find much about this metric in the Micronaut documentation and I don't want to make assumptions about what this metric means.

Which unit is this metric in and how could I convert this to a percentage value (from 0% to 100%)?

Does this answer your question? [Prometheus. CPU process time total to % percent](https://stackoverflow.com/questions/62384757/prometheus-cpu-process-time-total-to-percent) – Jeff Scott Brown Dec 15 '21 at 17:09
Thanks @jeff-scott-brown , I know how to convert CPU seconds to a percentage, but I am specifically referring to Micronaut's `system_cpu_usage` metric. – AbdelHajou Dec 15 '21 at 18:05
Apologies. I thought they were the same. – Jeff Scott Brown Dec 15 '21 at 18:11
