The Memory Usage page within the Admin Console shows information about current memory utilization within the LabKey Server process.

Memory Graphs

The top section of the page shows graphs of the various memory spaces within the Java Virtual Machine, including their current utilization and their maximum size. The Heap and Metaspace sections are typically the most likely to hit their maximum size.

Object Tracking

When the server is running with Java asserts enabled (via the -ea parameter on the command-line), the bottom of the page will show key objects that are tracked to ensure that they are not causing memory leaks. This is not a recommended configuration for production servers.


The links at the top of the page allow an administrator to clear the caches and request that the Java Virtual Machine perform a garbage collection to free memory claimed by unused objects. This can be useful to see how much memory is truly in use at a given point in time.
