Parse a JVM thread dump (jstack output) and analyze thread states, detect deadlocks, identify lock contention hotspots, and find thread starvation patterns. Handles both platform threads and virtual threads (Java 21+). Note: deadlock detection covers synchronized monitor locks only — java.util.concurrent.locks.ReentrantLock and other j.u.c lock types do not expose their waiters in thread dump lock info and will not be detected.

Generate an exportable diagnostic report (HTML + PDF) from JVM diagnostic data. Requires a valid Pro license key.

Parse a JVM GC log and analyze garbage collection patterns, pause times, allocation rates, and memory pressure. Supports G1, ZGC, Parallel, Serial, and Shenandoah GC formats.

Parse jmap -histo output and detect memory leak candidates, object creation hotspots, classloader leaks, and heap composition issues.

Compare two jmap -histo snapshots taken at different times to detect memory growth patterns, leak candidates, and new allocations. Captures what is growing between snapshots.

Parse JDK Flight Recorder summary output and analyze event distribution, detect performance hotspots, GC pressure, lock contention, I/O patterns, and excessive allocations. Input must be the text printed to stdout by jfr summary <recording.jfr> — not the binary .jfr file itself.

Unified JVM diagnosis combining thread dump and GC log analysis with cross-correlation. Detects deadlocks, lock contention, GC pressure, and GC-induced cascading thread blocks. When both inputs are provided from the same time window, cross-correlates high GC overhead with contention and flags long GC pauses causing thread starvation. Either input can be omitted for single-source analysis.
