Built-in probes

We have prepared a set of probes to help investigating typical problems. The probes are ready to use out of the box. Also you can use them as good examples to start with should you decide creating custom probes.

The following built-in probes are available at the moment:

  • com.yourkit.probes.builtin.Servlets - JSP/Servlet requests
  • com.yourkit.probes.builtin.Databases - JDBC/SQL database connections and requests
  • com.yourkit.probes.builtin.MongoDB - MongoDB requests
  • com.yourkit.probes.builtin.Cassandra - Cassandra database requests
  • com.yourkit.probes.builtin.HBase - HBase database requests
  • com.yourkit.probes.builtin.JPA_Hibernate,
    com.yourkit.probes.builtin.JPA_DataNucleus - JPA calls
  • com.yourkit.probes.builtin.Sockets - socket I/O operations via streams and NIO channels
  • com.yourkit.probes.builtin.AsyncChannels - socket I/O operations via asynchronous channels
  • com.yourkit.probes.builtin.Files - file I/O operations via streams, random access files, NIO channels
  • com.yourkit.probes.builtin.Threads - thread creation, start, name change.
  • com.yourkit.probes.builtin.Processes - external processes launched via Runtime.exec() and ProcessBuilder.start()
  • Class loading - class load and unload events. Read more...
  • com.yourkit.probes.builtin.JUnitTests - execution of JUnit tests
  • com.yourkit.probes.builtin.TestNG - execution of TestNG tests
  • com.yourkit.probes.builtin.AwtEvents - long AWT/Swing events, which cause UI irresponsiveness. Read more...
  • com.yourkit.probes.builtin.JNDI - JNDI calls

Also, the package com.yourkit.probes.builtin contains utility class com.yourkit.probes.builtin.Messages providing means to log arbitrary text messages from within probes.
