3 j_syscolors.d - trace Java method flow plus syscalls, in color.
8 This traces Java methods if the hotspot provider exists (1.6.0) and
9 the flag "+ExtendedDTraceProbes" is used. eg,
10 java -XX:+ExtendedDTraceProbes classfile
12 This watches Java method entries and returns, and indents child
15 If the flow appears to jump, check the TID column - the JVM may have
16 switched to another thread.
20 Evolving - uses the DTrace hotspot provider, which may change
21 as additional features are introduced. Check Java/Readme
22 to see what version these scripts are based on.
41 Elapsed time from previous line to this line
44 Type of call (func/syscall)
47 Java method or syscall name
49 Watch the first column carefully, it prints the CPU-id. If it
50 changes, then it is very likely that the output has been shuffled.
51 Changes in TID will appear to shuffle output, as we change from one thread
52 depth to the next. See Docs/Notes/ALLjavaflow.txt for additional notes.
55 See the DTraceToolkit for further documentation under the
56 Examples, Notes and Docs directories. The example files may be
57 especially useful as they aim to demonstrate how to interpret
60 j_syscolors.d will run until Ctrl-C is hit.
