We will learn how to query Prometheus 1.3.1. In order to have fitting example data to work with, we will set up three identical demo service instances that export synthetic metrics of various kinds. We will then set up a Prometheus server to scrape and store those metrics. Using the example metrics, we will then learn how to query Prometheus, beginning with simple queries and moving on to more advanced ones.
Prometheus is an open source monitoring system and time series database. In part 1 of this series, you will learn how to select and filter time series based on their dimensions, aggregate and transform time series, as well as how to do arithmetics between different metrics in Prometheus 1.3.1.
Prometheus is an open source monitoring system and time series database. In part 2 of this series, you will build on the setup from the first part and learn more advanced querying techniques and patterns to apply value-based filtering, set operations, histograms, and more.
