Prometheus integration

Prometheus is a system monitoring and alerting application that records real-time metrics in a time series database. LoadRunner Enterprise's Prometheus monitor fetches measurements from the Prometheus server and displays them during the performance test run in the online and offline Prometheus graphs.

For example, if you use Prometheus to monitor your load generator machine, you can select Prometheus measurements related to the load generator to display in LoadRunner Enterprise.

We recommend using the latest stable version of Prometheus when working with LoadRunner Enterprise's Prometheus integration.
