Summary
In this chapter, we learned all about Prometheus’s most popular exporter, the Node Exporter. We went over the basics of what an exporter is and what is involved in creating one. Then, we dove headfirst into the dozens of collectors that the Node Exporter enables by default. Finally, we looked at how to use the textfile collector and how to troubleshoot issues with the Node Exporter.
In our next chapter, we’re going to be stepping out of the realm of “vanilla” Prometheus and begin looking at how we can extend and augment Prometheus through the use of other open source projects. To begin, we’ll see how projects such as VictoriaMetrics and Grafana Mimir can function as remote storage for Prometheus metrics.
