1 1.1 christos Java - DTracing Java 2 1.1 christos 3 1.1 christos These scripts trace the JVM, and require the Java hotspot provider which 4 1.1 christos was shipped with Java starting with version 1.6.0. 5 1.1 christos 6 1.1 christos Some of these scripts measure method and object events, and require 7 1.1 christos the Java process to be run using the "+ExtendedDTraceProbes" flag. 8 1.1 christos For example, 9 1.1 christos 10 1.1 christos java -XX:+ExtendedDTraceProbes classfile 11 1.1 christos 12 1.1 christos The ExtendedDTraceProbes flag is not on by default to avoid the additional 13 1.1 christos overhead for maintaining these additional probes. When this flag is 14 1.1 christos enabled, the JVM may execute slightly slower than before; when the probes 15 1.1 christos are also enabled (especially method probes), the JVM may execute 16 1.1 christos significantly slower. 17 1.1 christos 18
