Exporters are configured and services are running, but no OpenTelemetry data reaches Instana. Which check comes first?
Select an answer to reveal the explanation.
Short Explanation
If nothing arrives, you've got a path problem. Check that the exporters can reach the ingestion endpoint and port before you mess with sampling, retention, or naming.
Full Explanation
The correct check is to confirm the configured ingestion endpoint is correct and reachable from the exporters, including the required port through any firewall. A total absence of data points to the transport path rather than the content, so endpoint address and firewall reachability are the first things to verify. Increasing the trace sampling rate is incorrect because sampling changes how much of something is sent, and there is currently nothing. Extending retention is incorrect because retention governs how long stored data is kept, not whether it is accepted. Applying service naming rules is incorrect because naming rules apply to data that has already arrived. For the exam, diagnose no-data conditions at the connectivity layer first.
