Comparison — Logs, metrics and traces: why is your application slow?
Side-by-side analysis to help you choose
Three complementary signals help move from noticing a problem to understanding where it happens.
Approaches compared
Metrics show patterns
Metrics summarize request volume, error rates and response duration over time. Averages can hide slow requests, so inspect latency percentiles. Alert on sustained user impact rather than every brief increase in CPU usage.
Logs explain events
Structured logs record request IDs, actions and error types. They help find events around failures. Avoid passwords, tokens and full customer documents. Set retention and access rules because operational data can still contain personal information.
Traces connect the journey
A trace follows a request through the API, database and external calls. Its spans reveal which step took time. OpenTelemetry provides instrumentation and export mechanisms; you still need a backend to store and explore signals.
Our recommendation : Metrics reveal patterns, logs explain events and traces connect request steps.
