Cannot monitor Java process #247

Closed tjiuming closed 1 year ago

tjiuming commented 1 year ago

Hi community,

I had run a Java process on my computer, and I want to monitor per-thread CPU usage of the process by using process-exporter.

  1. process-exporter config file:

    process_names:
- name: "{{.Comm}}"
cmdline:
- '[.\n]*'

  2. outputs by ps -ef

    [root@iZwz9fvw6m5ezres364g9hZ process-exporter-0.7.10.linux-386]# ps -ef | grep java
