The Environment Variables section displays environment variables recognized on your system with their current values. This includes the environment variables defined by Jenkins that are available on all systems, as well as environment variables associated with plugins installed on this controller.

Plugins

The Plugins section provides a comprehensive list of all installed plugins, including their names, versions, and other relevant details.

Memory usage

The Memory Usage section provides a graphical representation of the controller’s memory usage, categorized into three timespans for better analysis:

Short: The short timespan covers memory usage over the last few minutes, broken down by seconds, for real-time monitoring.
Medium: The medium timespan displays memory trends over the past hour, broken down by minutes, which is useful for detecting gradual memory leaks.
Long: The long timespan illustrates extended memory usage patterns over a day or month to identify recurring issues. This breakdown allows administrators to monitor memory trends, detect unusual spikes, and optimize resource allocation.

Thread dump

The Thread Dump section provides a link to a page that captures a real-time snapshot of all active threads running in the Jenkins controller’s JVM. This is essential for diagnosing performance issues, deadlocks, or excessive CPU utilization.
