Yes, APM and observability can be used independently, but they are most effective when combined:
-APM without Observability can help track application performance, but it lacks the depth and context required to fully understand system behavior or to quickly pinpoint the cause of issues.
– Observability without APM can provide detailed traces and logs, but without the performance-focused metrics from APM, teams might struggle to identify and address real-time performance issues.
Together, they offer a comprehensive view of system health, from high-level performance indicators to low-level root cause analysis.
