Can one instance of apache_exporter monitor two or more apache instances?

[ping2nomula]

We have two or more apache instances on the same host and wants to monitor it using apache_exporter. Do i need to have more instances of apache_exporter running or one is enough?

You need multiple instances.
Prometheus philosophy is to have one exporter process for each thing being monitored.

Would multiple vhosts/sites be considered multiple 'instances'? Also doesn't your phpfpm_exporter handle multiple instances via --phpfpm.socket-paths?

Example: Server running 3 vhosts, and two versions of php. With this setup I use one phpfpm_exporter with the two php versions. But I need to setup 3 apache_exporters(0-2) to accommodate each vhost/site.

Of course I don't know golang/apache/php well anyway, so if this is an annoying (my example setup is flawed for instance) question feel free to ignore.

Thanks.

Apache can serve multiple vhosts from the same process. Therefore you'll only need a single exporter. Phpfpm exporter does *not follow the convention*, because you can create multiple fpm pools and need to monitor each one individually, and the exporter will monitor all from one instance (against convention) If you’re running different Apache instances, because you may want to segregate stats per vhost, then you’ll need different exporters for each instance Also, both exporters were originally written by other people, I've only added small things or review Pull Requests. Not intending to release incompatible changes to follow the convention at this point. Hope it’s clear

Don’t suppose anyone has an example of how to set this up with kubernetes?

I’m able to create two separate services in k8ns, but not sure how I could get each individual pod running the apache exporter to connect directly to a pod running Apache.

Typically you use a "sidecar container pattern" approach So each Apache container will have an apache exporter sidecar container Maybe this article can guide you https://medium.com/bb-tutorials-and-thoughts/kubernetes-learn-sidecar-container-pattern-6d8c21f873d
