Not getting any process metrics from process exporter on Debian 12 (bookworm) #285

Open darknetehf opened 8 months ago

darknetehf commented 8 months ago

Hi,

This is a possibly related issue: #284

Output of prometheus-process-exporter -version:

process-exporter, version  (branch: debian/sid, revision: 0.7.10-3+b5)
  build user:       team+pkg-go@tracker.debian.org
  build date:       20230409-10:13:36
  go version:       go1.19.8
  platform:         linux/amd64

OS: Debian GNU/Linux 12 (bookworm) How the package was installed: the package was installed using Ansible:

    - name: "Install Prometheus exporters"
      apt:
        name:
          - prometheus-node-exporter # 9100
          - prometheus-postfix-exporter # 9154
          - prometheus-process-exporter # 9256

Running in debug mode, on a different port (9257): prometheus-process-exporter -debug -web.listen-address :9257 We can see that process discovery seems to be taking place normally, but no metrics are returned on the /metrics endpoint:

Update and possible fix:

I installed the package manually from this repo instead of using the Debian package. In the releases I picked this file: process-exporter_0.7.10_linux_amd64.deb and installed it with dpkg.

It should be noted that there are differences between this package and the Debian package version. On Debian the systemd service is named: prometheus-process-exporter.service In ncabatoff package it is: process-exporter.service

The unit files differ as well:

On Debian:

● prometheus-process-exporter.service - Prometheus exporter that mines /proc to report on selected processes
     Loaded: loaded (/lib/systemd/system/prometheus-process-exporter.service; enabled; vendor preset: enabled)
     Active: active (running) since Wed 2023-12-20 18:27:04 GMT; 4h 5min ago
       Docs: https://github.com/ncabatoff/process-exporter
             man:prometheus-process-exporter(1)
   Main PID: 4095383 (prometheus-proc)
      Tasks: 5 (limit: 1115)
     Memory: 20.0M
        CPU: 2.980s
     CGroup: /system.slice/prometheus-process-exporter.service
             └─4095383 /usr/bin/prometheus-process-exporter

ncabatoff:

● process-exporter.service - Process Exporter for Prometheus
     Loaded: loaded (/lib/systemd/system/process-exporter.service; enabled; preset: enabled)
     Active: active (running) since Wed 2023-12-20 22:16:30 GMT; 15min ago
   Main PID: 4727 (process-exporte)
      Tasks: 5 (limit: 1108)
     Memory: 16.5M
        CPU: 3.066s
     CGroup: /system.slice/process-exporter.service
             └─4727 /usr/bin/process-exporter --config.path /etc/process-exporter/all.yaml --web.listen-address=:9256

And the EnvironmentFile directive in the systemd unit file differs as well. The file /etc/process-exporter/all.yaml is not present when installing the Debian package. Contents:

process_names:
  - name: "{{.Comm}}"
    cmdline: 
    - '.+'

This seems to be the missing piece.

A quick fix is to create that missing all.yaml file and adapt the service CLI to use that config file: For example this command will properly expose the metrics on port 9257: /usr/bin/prometheus-process-exporter -debug --web.listen-address=:9257 --config.path /tmp/all.yaml

In conclusion the issue seems to be with the Debian packaging.

Quick fix for Debian package

Listing files provided by package: apt-file list prometheus-process-exporter Output:

prometheus-process-exporter: /etc/default/prometheus-process-exporter
prometheus-process-exporter: /etc/init.d/prometheus-process-exporter
prometheus-process-exporter: /etc/logrotate.d/prometheus-process-exporter
prometheus-process-exporter: /lib/systemd/system/prometheus-process-exporter.service
prometheus-process-exporter: /usr/bin/prometheus-process-exporter
prometheus-process-exporter: /usr/share/doc/prometheus-process-exporter/README.md.gz
prometheus-process-exporter: /usr/share/doc/prometheus-process-exporter/changelog.Debian.amd64.gz
prometheus-process-exporter: /usr/share/doc/prometheus-process-exporter/changelog.Debian.gz
prometheus-process-exporter: /usr/share/doc/prometheus-process-exporter/copyright
prometheus-process-exporter: /usr/share/doc/prometheus-process-exporter/examples/all.yaml
prometheus-process-exporter: /usr/share/man/man1/prometheus-process-exporter.1.gz

The all.yaml file is provided so it is sufficient to edit this file: /etc/default/prometheus-process-exporter as follows: ARGS="-config.path /usr/share/doc/prometheus-process-exporter/examples/all.yaml" Then restart the service: systemctl restart prometheus-process-exporter Process metrics will be returned on the /metrics endpoint on port 9256.
