Hi!Do you have a complete description of metrics for prometheus?

Hi @newjett0617 , unfortunately we don't have a documentation for that. But if you are interested, you may take a look at the following two source code files:

• manager_metrics.ts
• shared_metrics.ts

And also, please feel free to search "Prometheus" within our repository, you should be able to see a bunch of code related to it.
