Capture snapshots periodically

Please also consider the ability to capture memory snapshots on high memory usage or on OutOfMemoryError.

You can instruct the profiler to capture a snapshot after a specified period of time.

When used memory constantly increases, this often means there is a memory leak. This feature greatly simplifies the detection of such situations in e.g. long-running applications such as servers. One of the benefits is that, after being triggered, the feature requires no further human interaction.

To toggle this feature, connect to the profiled application and click toolbar button.

Use corresponding template menu to add the trigger and actions, then edit parameters if necessary:

Then, every time the specified period elapses, a memory snapshot will be created and the following notification will be shown in the UI:

How to trigger the snapshots from the start
