Hi,I'm not sure if I have correctly understood your question. Do you mean 'metrics'?

The Java client listens on the SIGUSR2 signal, you can get metrics data through 'kill -s SIGUSR2'. For detailed information, please refer to the following document:

I think @ZY945 meant the GreptimeDB metrics, you can find them at the http://ip:4000/metrics endpoint, the ip is your greptimedb server ip.

kill -s SIGUSR2 pid Thank you very much. This is a good method. Will it affect the normal use of greptimedb?

It won't affect the normal running of the GreptimeDB client , it merely outputs some information.
