How to get JVM xmxBytes metrics using Java

Am Anonymous :

I am trying to get xmxBytes (size) metrics for monitoring jvm but I am unable to get from a java program.

I am using this package import: java.lang.management.RuntimeMXBean;
and this method:

RuntimeMXBean runtimeMXBean = ManagementFactory.getRuntimeMXBean();         
List<String> argument = runtimeMXBean.getInputArguments();`

Can anyone tell me?

Peter Lawrey :

Try the following.

long max = Runtime.getRuntime().totalMemory();
