Free IBM Instana Observability v1.0.277 Administrator – Professional Practice Questions

IBM Instana’s Service Level Indicator (SLI) configuration capabilities emphasize trace-based and event count-based SLIs. The verified guide details: "Instana supports SLI definitions based on distributed trace data and event counts, such as request rate, error rate, or latency." Trace-based SLIs allow direct measurement of real user or synthetic transactions for detailed performance objectives (e.g., 99th percentile response time). Event count-based SLIs track operational markers such as number of errors, alerts, or specific incidents—essential for regulatory uptime or compliance audits. Error logs, time-based or alert-based SLIs can be visualized but are not supported as direct SLI definitions by Instana, according to verified IBM configuration steps. The combination of traces and event counts provides the flexibility to set quality objectives, measure reliability, and drive alerting in line with SRE principles.
