What must you confirm to troubleshoot Dynatrace OpenKit instrumentation?

To troubleshoot Dynatrace OpenKit instrumentation effectively, it is essential to confirm that the ActiveGate has a valid SSL certificate. The ActiveGate acts as an intermediary between your monitored applications and the Dynatrace platform, facilitating secure data transmission. If the SSL certificate is invalid or misconfigured, it can lead to connection issues, resulting in incomplete or failed data reporting from the instrumentation. Ensuring the certificate is correctly set up is crucial for maintaining a secure and functional link between the OpenKit-instrumented application and Dynatrace, enabling accurate monitoring and insights.

In contrast, confirming whether the application is recently updated, whether the network is offline, or if the application is specifically written in Java or .NET does not directly relate to troubleshooting OpenKit instrumentation. While these factors can influence the overall health of an application or its performance, they are not primary considerations for resolving instrumentation issues in this context.
