  • Thread and Monitor Profiling - detecting thread contention.
  • VM Telemetry - To observe the internal state of your JVM
  • JEE Probes
  • NoSQL and big data probes - Bottlenecks in MongoDB, Cassandra and HBase can now be analyzed with JProfiler.
  • Remote tracking allows you to follow calls from one profiled JVM to another. RMI, web services and remote EJBs are supported.
  • Profiling modes There are four different profiling modes in JProfiler: Attach mode, Profile at startup, Prepare for profiling and Offline profiling
