The node exporter includes many metrics out of the box, it can't possibly cover all use cases though. That's where the textfile collector comes in, allowing you to extend machine instrumentation for your use case.
It's a best practice with Prometheus that target labels should be constant over a target's entire lifetime. On the other hand it's useful to aggregate metrics across all the machines that are currently Apache servers. How can we do that?
Sometimes you need a machine metric that's not exported yet by the node exporter. The textfile collector can be used to quickly get such metrics graphed in Prometheus.
