Process-Matches wierd about process-exporter HOT 6 CLOSED

@zelonkaa Hi, i am facing the same issue. Are you able to figure out why it it showing the higher number of processes ?. Below is the part of the ConfigMap. i have only 2 processes running but process-exporter metrics are showing as 6. I am not able to figure out what's wrong with my config Map

namedprocess_namegroup_num_procs{groupname="/usr/bin/bash:-c:/usr/bin/journalctl"} 6

• name: /usr/bin/bash:-c:/usr/bin/journalctl
  exe:
  - /usr/bin/bash
  cmdline:
  - -c
  - /usr/bin/journalctl

hi @amitsingla it really looks similar but in fact isn't.

What the process exporter looks for with my current understanding is the following:
pid=180176 -> process_exporter
ls -la /proc/180176/{comm,exe,cmdline}
-r--r--r-- 1 root root 0 May 2 16:56 /proc/180176/cmdline
-rw-r--r-- 1 root root 0 May 4 12:13 /proc/180176/comm
lrwxrwxrwx 1 root root 0 May 2 16:56 /proc/180176/exe -> /usr/local/bin/prometheus_process_exporter/prometheus_process_exporter

As far as I understand the documentation, only if you use the cmdline-Check in the config.yml , these expressions have all to match in order to find a process (logical-AND), in the other cases you have (logical-OR).

In your case if you have any "/usr/bin/bash"-Processes, they are listed as well.

In my case it doesn't matter, either with or without other parameters (EXE/COMM/CMDLINE) I always get the same amount of processes found.

Note that by default, the -children argument is true, meaning any child processes of the matched processes will be included in the group.

Thanks for the hint, I thought that it could be an issue with this parameter. Tried with and without "-children false", in both cases I get the same amount of processes (34) as a metric.

The newest pre-release 0.3.7 includes a -debug option that may answer your question. I suggest using it with the -once-to-stdout option as it produces quite a lot of output.
