JMXProfiler

JMXProfiler is a lightweight sampling JVM profiler based on JMX technology. It gets the values of the attributes of specified MBeans of a Java application and prints them in various formats.

Distinctive Features

• The printing of MBeans as JSON objects.
• The indexing of MBeans in Elasticsearch.
• The plotting of the decimal values of the attributes of MBeans as PNG/GIF/JPG charts via XChart library.
• The filtering of the attributes of MBeans via regular expressions.

Build

Run the Maven command

mvn clean package assembly:single

Install

Unpack ./target/jmxprofiler-<version>-bin.zip archive into a suitable directory.

Run

All parameters of the tools are passed only via command line options.

Examples

In all examples, the profiler connects to an application that is run on a local host with JMX port 65000.

Example #1

Print JSON objects that corresponds to GarbageCollector MBean objects:

java -Dlog4j.configurationFile=./config/log4j2.xml -jar ./lib/jmxprofiler-<version>.jar
--jmx-port=65000
--jmx-mbean-object-name="java.lang:type=GarbageCollector,*"
--printer=json_console

There are the following 6 variants of the options of garbage collection algorithms in HotSpot JVM:

Young Collector	Old Collector	JVM Option(s)
Serial (DefNew)	Serial Mark-Sweep-Compact	-XX:+UseSerialGC
Parallel scavenge (PSYoungGen)	Serial Mark-Sweep-Compact (PSOldGen)	-XX:+UseParallelGC
Parallel scavenge (PSYoungGen)	Parallel Mark-Sweep-Compact (ParOldGen)	-XX:+UseParallelOldGC
Serial (DefNew)	Concurrent Mark Sweep	-XX:+UseConcMarkSweepGC -XX:-UseParNewGC
Parallel (ParNew)	Concurrent Mark Sweep	-XX:+UseConcMarkSweepGC -XX:+UseParNewGC
G1		-XX:+UseG1GC

The profiler prints the following JSON objects for each garbage collection algorithm:

• Serial (DefNew) - Serial Mark-Sweep-Compact
