[Feature] Linux Process Monitoring within Infrastructure/Linux services with process-exporter

Search before asking

• I had searched in the issues and found no similar feature requirement.

Description

Process-exporter from https://github.com/ncabatoff/process-exporter/releases/ can be used to monitor selected processes within a linux host. The information then can be accessed by other skywalking components like alerts and so on.

Use case

Most hosts are there for running daemons processes or the like. Monitoring services health often requires to know if a given process is running in a host and also understand resources usage by this processes of interest. Receiving alerts on critical processes not running is very important for managing distributed systems.

Related issues

None. Already implemented and tested in my setup, easy to integrate like other use cases already available such as nginx monitoring.

Are you willing to submit a pull request to implement this on your own?

How different it is with the existing Linux monitoring?

[mike-realuptime]

Current Linux monitoring doesn’t include process monitoring , as per my knowledge The screenshots below show postgresql process being monitored:    As you can see , there’s individual processs monitoring within Infrastructure/Linux service instances.

I can't see your screenshots, could you update them?

Images uploaded :)

Generally, it is fine to add instances to indicate processes on the OS. But you need to polish the words and explanation, and choose proper graphs. There are spaces to optimize.

This is mi first contribution, please give some advice to provide something with enough quality. The setup as of today considers: otel-rules for process, widgets added on the Linux/Service panel as you can see, and process-exporter setup and related otel-collector configuration.

1. You need to set up e2e for the CI pipeline, refer to existing cases. This pipeline could run all the installation and check the generation metrics via swctl.
2. The document should be updated, as for Linux monitoring, there are two sources.
3. All widget names should be readable with tips to explain what they are. Current screenshots show they are metric names only.
4. If this PR gets merged later, you need to update the showcase to help new users to try this feature, https://github.com/apache/skywalking-showcase doc is https://skywalking.apache.org/docs/skywalking-showcase/next/readme/
