An SRE is investigating latency on the product catalog service. In the Instana Service Map for their Application Perspective, three downstream dependencies are shown with red node indicators. What do these red indicators most likely represent?

In Instana's Service Map, color-coded health indicators on service nodes reflect the current metric health status—red typically means error rate, latency, or throughput has exceeded configured thresholds or that Instana's anomaly detection has identified an issue. This visual cue helps SREs quickly narrow down which downstream dependencies are likely contributing to the observed latency. An agent connectivity issue would appear differently in the Infrastructure view and would not necessarily color the service node red in the Service Map context. The correct answer is 'Those services have error rates or latency that exceeds defined thresholds or Instana has detected anomalies'. The incorrect options — 'Those services are completely unreachable and generating TCP-level connection timeouts', 'Those services are not fully configured for monitoring and need additional agent setup', 'The Instana agent on those services has lost its connection to the Instana backend' — are wrong because they do not align with IBM Instana's architecture or recommended practices for this scenario. Understanding this concept is essential for the Domain 1: Operations domain of the IBM Instana Observability certification.
