Prometheus Agent View

Prometheus Agent is a lightweight version of Prometheus Server. It scrapes the metrics for all hosts and components. The metrics data is then reported to and stored on AOM or a third-party monitoring platform. The Prometheus Agent view displays some built-in metrics provided by Prometheus, which can be used to monitor and measure system performance and status.

Metric Description

You can view Prometheus Agent metrics in the following table.
