Java BufferPool Monitoring

Rajendra — Tue, 14 Jan 2025 08:09:41 GMT

Hi,

Would like to monitor BufferPool Memory consumed for a java Microservice. Can anyone please advise on the possibilities through Dynatrace.

getMemoryUsed

https://docs.oracle.com/javase/8/docs/api/java/lang/management/BufferPoolMXBean.html#getMemoryUsed--

Thanks,

Rajendra

Hi,

You can find here all JVM metrics out-of-the-box.

If it not there, you can explore JMX extensions.

Best regards

One addition/note to Anton's reply - JMX extensions likely would be the way to go but that documentation links to the 1.0 extensions framework which will still be around for quite a while but the latest way to handle these is within the 2.0 extensions framework.
