How to extract the running process using prometheus node exporter?

Question

I have downloaded the prometheus node exporter in prometheus official site https://prometheus.io/download/ for my linux system.

If i run the node exporter file , it is running fine and able to see the metrics in 9100 port.

In 9100 metrics , i am looking to extract the running process (for example: i need to extract any running application like 'chrome' browser) , but i do not have any config files inside the node exporter directory to filter the running process.

Is their any commands available to filter the required running process in node exporter like, ./node_exporter "filter process like 'chrome'"

can i use "prometheus.yml" file 'labels' to filter running process in my linux system.

Kindly suggest me , how to extract the running process and system details in node exporter.

Do you mean you have the process statistics but want to filter them or do you mean you have no process metrics and wonder if there is a filter preventing that ? There is no config file, all options are on the command line (easier to operate in a container). – Reconstruct

Node Exporter is oriented towards providing measurements on machine-level (kernel|OS) metrics.

It is possible to configure Node exporter to surface aggregate (!) process measurements but not possible to configure it to surface per-process measurements. The reasoning is that measurements over a reasonable number of processes could swamp the exporter.

There is a (companion) solution that will permit you to report on a filtered set of processes. I've not used this but found it while responding to your question:

I've seen process-exporter used and it's pretty impressive. IIRC there was even a really cool Grafana dashboard for it (there are a handful if you search, not sure which one I saw). – Lipography
