For the metrics of TiDB/PD/TiKV/TiFlash components collected by Prometheus as mentioned above, is there any documentation explaining the meaning of each metric?

For example, like this one:

I’m not sure if this is the content you need~

This is just an explanation of the metrics displayed by Grafana (data sourced from Prometheus), which is far less than the metrics provided by each component. Is there a more detailed and comprehensive explanation document?

Generally, there isn’t one, but if you use curl to fetch the metrics, there is help information available. You can basically understand it through the English annotations.

If there is no detailed documentation, this is the only way.
