A file chooser will be brought up where you can select the name and directory of the snapshot file to be written. The standard extension of JProfiler's snapshot files is *.jps. Once JProfiler has finished writing the snapshot to disk, a message box informs you that the snapshot was saved.
In situations where physical memory is sparse, saving an HPROF snapshot can be preferable compared to saving a full JProfiler snapshot. Also, there are alternative ways to save HPROF snapshots:
The following restrictions apply when viewing snapshots:
After a JProfiler snapshot has been loaded, the functionality of all views is identical to a live profiling session with the exception of the heap walker view: The heap walker overview will be shown if a heap snapshot was taken at the time of saving, otherwise the heap walker will be unavailable.
When an HPROF snapshot is loaded, only the heap walker is available. Also, the "Allocations" and "Time" views of the heap walker are not available.
The status bar indicates that a snapshot is being viewed by displaying the
message Snapshot
in its rightmost compartment.
