Summary, snapshot annotation, automatic deobfuscation

The "Summary" tab provides an overview of JVM properties and parameters of profiled application, as well as a summary of application telemetry information.

The tab is available when the profiler is connected to profiled application, or when you open a saved snapshot.

Automatic deobfuscation

If the profiled application is obfuscated, YourKit Java Profiler can automatically restore original names of classes, fields and methods if you specify the path to the obfuscation log file (1). Deobfuscator can be configured for a specific snapshot, as well as when you are connected to the profiled application (in this case the deobfuscator will apply to live results and will be chosen by default for captured snapshots).

Snapshot annotation

Snapshot annotation is a free-form text descriptions directly in the snapshot file.

Annotation can be viewed and edited on the "Summary" tab of snapshot (2), on the Welcome screen:

... and from "Open Snapshot" dialog:

Snapshot annotation is supported for the profiler-format snapshots only i.e. .snapshot files. A HPROF snapshot cannot be annotated because the HPROF file format does not allow records with arbitrary content.
