1N/A * j_syscolors.d - trace Java method flow plus syscalls, in color. 1N/A * Written for the Java hotspot DTrace provider. 1N/A * $Id: j_syscolors.d 58 2007-10-01 13:36:29Z brendan $ 1N/A * This traces Java methods if the hotspot provider exists (1.6.0) and 1N/A * the flag "+ExtendedDTraceProbes" is used. eg, 1N/A * java -XX:+ExtendedDTraceProbes classfile 1N/A * USAGE: j_syscolors.d { -p PID | -c cmd } # hit Ctrl-C to end 1N/A * This watches Java method entries and returns, and indents child 1N/A * DELTA(us) Elapsed time from previous line to this line 1N/A * NAME Java method or syscall name 1N/A * If the flow appears to jump, check the TID column - the JVM may have 1N/A * switched to another thread. 1N/A * WARNING: Watch the first column carefully, it prints the CPU-id. If it 1N/A * changes, then it is very likely that the output has been shuffled. 1N/A * Changes in TID will appear to shuffle output, as we change from one thread 1N/A * COPYRIGHT: Copyright (c) 2007 Brendan Gregg. 1N/A * The contents of this file are subject to the terms of the 1N/A * Common Development and Distribution License, Version 1.0 only 1N/A * (the "License").
