How to troubleshoot JMX metric collection issues | Datadog Tips & Tricks

Missing JMX metrics make it hard to know what’s happening in a Java application, especially when vague errors or configuration mismatches make the cause difficult to diagnose.

In this video, you’ll see how to troubleshoot common JMX metric collection issues and isolate the cause in less time.

Learn how to:

• Confirm a third-party client can connect to your Java application’s JMX endpoint
• Check that the Datadog Agent and application configurations match
• Use “datadog-agent jmx” commands to validate what the Agent is collecting
• Avoid collecting more metrics than you need to reduce custom-metric costs
