No Telemetry; NotificationListener class not found

Postby Steven Buytaert » Tue Nov 21, 2017 11:28 am

Hi,

Starting up the agent on a remote and embedded system, that has no javax.management classes, I get the following:

Exception in thread "YJPAgent-Telemetry" java.lang.NoClassDefFoundError: javax/management/NotificationListener
at com.yourkit.runtime.TelemetryThread.getTelemetryCounters(TelemetryThread.java:902)
at com.yourkit.runtime.TelemetryThread.run(TelemetryThread.java:569)

I do have a connection to the agent and I can make heap snapshots, but the telemetry to check the GC and internal memory usage of the JVM is also important, but is now missing. Is there a way to change the telemetry to use an alternative class?

Kind regards,

Steven

Hi Steven

Could you please provide the profiler agent log file ~/.yjp/log/<session name>-<pid>.log
You may send it attached to support@yourkit.com

Best regards,
Anton
