APM (application performance monitoring) measures how cloud applications behave for users by tracking latency, errors, throughput and code-level traces.
Distributed tracing follows a single request across services and records each step as timed spans, revealing where latency and errors arise.
An error budget is the amount of unreliability a service may spend in a period, equal to one minus its SLO target, used to balance releases…
Logs in observability are timestamped records of discrete events emitted by applications and infrastructure, used to debug, audit and explain system behavior.
Metrics in observability are numeric measurements collected at intervals as labeled time series, used to track system health, alert on problems and spot trends.
OpenTelemetry is an open, vendor-neutral standard and toolkit for generating, collecting and exporting traces, metrics and logs from cloud applications.
Traces in observability record the path of one request through a system as a tree of timed spans, showing where time was spent and where errors…
