Can't get JVM metrix from application's JVM about jmx_exporter HOT 9 CLOSED

Can you indicate exactly which version generated that error?

from jmx_exporter.

This was jmx_exporter version 0.7

from jmx_exporter.

Okay, looks like an issue with a composite. What are you monitoring?

from jmx_exporter.

It's our company's inner application.

from jmx_exporter.

So you've custom mBeans implemented? Can you turn on the debugging and see which mBean it is and what it's doing? See http://www.robustperception.io/viewing-logs-for-the-jmx-exporter/

I turned on debugging and jmx_exporter got some scrapr failed:

and I can't see any metrics from JMV (such as java_lang_GarbageCollector_LastGcInfo_memoryUsageAfterGc_max{name="PS MarkSweep",key="Compressed Class Space",} 1.073741824E9) in debug output.

If you could debug your custom mBean and submit a unittest emulating how it's breaking we can get this fixed, as without your code I can't do much.

Hi ,this issue also happen in my project , do you resolve it?

from jmx_exporter.

Hi, no the problem is not resolved. At the end our developers is implement metric exporter direct into application.
