+### System resources
+
+Logging of system resources is disabled by default. When
`taskmanager.debug.additional-logging`
+is enabled on a TaskManager additional metrics listed below will be available.
System
+resources metrics are updated periodically and they present average values for
a configured
+interval (`taskmanager.debug.additional-logging-interval`).
+
+Logging of system resources require couple of optional dependencies to be
present on the
+classpath (for example placed in Flink's `lib` directory):
+
+ - `com.github.oshi:oshi-core:3.4.0` (licensed under EPL 1.0 license)
+ - `net.java.dev.jna:jna-platform:jar:4.2.2`
