Exporting Metrics from Kubernetes Apps for Prometheus
Operators automate day 2 operations for Kubernetes based software. Operators need to know the state of their operands. One way to find out the state is to check metrics information stored in Prometheus. This article describes how to export metrics from applications running on Kubernetes to make them accessible by Prometheus. (more…)
