Working with Prometheus Metric Types
Prometheus exporters provide data using a handful of different metric types, each representing its own unique kind of data. When working with Prometheus, it is important to understand how these different metric types function in order to properly interpret data. In this lab, you will have the opportunity to collect data from metrics that utilize a variety of different metric types. This will allow you to work with multiple metric types hands-on.
