I use netdata to collect metrics and export them to timescaledb with data provider. After getting metrics from postgresql, I find netdata is a really inspiring and excellect tool.
With as-collected metrics I wanna output some meaningful metrics. For example, I wanna calclute cup utilization with metrics such as
I know that I can get metrics as
average and cpu utilization ratio is stored in the database directly. But here I wanna do it myself for flexible control and understanding of the system.
So, is there any document that describe the meaning/unit of the metrics?
If I wanna to lean how to calclute metrics in
average format, is there any document that help me to find the calcluting way from source code?
