ZingGCReporter

ZingGCReporter is a simple java agent that collects and reports GC activity stats when running on a Zing JVM. It uses the Zing Java Memory Management MXBeans to collect relevant information and summarize it in periodic reports that are meant to easily fit into time-series and other/similar stats logging and monitoring operational workflows.

Options:

[-v] [-i intervalLengthMsec] [-t runTimeMsec] [-l logFileName]

  • intervalLengthMsec [-i intervalLengthMsec, default: 10000]: Control the length of the periodic reporting intervals

  • logFile [-l logFileName, default: ] specifies the log file to output to. Outputs to standard output when unspecified

  • runTimeMsec [-t runTimeMsec, default: 0]: When run as main (not as an agent) and runTimeMsec is specified as non-zero, ZingGCReporter will exit after the configured amount of time

  • verbose [-v , default: false]: Causes verbose output e.g. when GC events are received

Note that options can use either spaces, commas, or semicolons as delimeters. E.g. "-i 1000 -v", "-i,1000,-v", and "-i;1000;-v" are all equivalent. This can be useful when e.g. javaagent parameters are included in the launching command line that are sensitive to the use of spaces within parameters.

Running:

ZingGCReporter will typically be added to existing Java applications as a javaagent. E.g. a typical command line will be:

java ... -javaagent:ZingGCReporter.jar MyApp myAppArgs

Or, when parameters need to be set:

java ... -javaagent:ZingGCReporter.jar="-i 5000 -l gcstats.log" MyApp myAppArgs

For a quick demonstration or test ZingGCReporter can be combined with e.g. HeapFragger. For example, the following command:

$JAVA_HOME/bin/java -Xloggc:ggc.log -Xmx5g -XX:+UseZingMXBeans -javaagent:ZingGCReporter.jar="-i 5000" -jar HeapFragger.jar -a 1024 -s 1024

Results in output that looks somewhat like this:

Building:

Note that to build ZingGCReporter outside of a Zing environment, the maven setup expects to find a copy of ZingJMM.jar in <basedir>/lib . You can generally find a copy of ZingJMM.jar (which includes the Zing JMXBean APIs) at $JAVA_HOME/etc/extensions/mxbeans/agents/ZingJMM.jar and copy it into your <basedir>/lib. Then just run:

mvn clean install

And you should find a feshly built ZingGCReporter.jar in your base directory.
