How do I monitor the nginx process?

[hulining]

When I start with the following command, I can monitor the nginx process. However,namedprocess_namegroup_num_procs{groupname="nginx"} metrics will occasionally not be 1 when nginx is reload.

• process.yml

process_names:
- comm:
  - nginx

• commond line

process-exporter -config.path ./process-exporter.yml 

I started 40 nginx worker processes, and the metrics labeled groupname="nginx" and groupname="nginx: worker process" add up to exactly 41.

Does anyone know what's going on?

Looking forward to your reply. Thanks a lot~
