Telemetry
In plain terms
Automated collection and transmission of system data.
Going deeper
Telemetry gathers metrics, logs, and traces from systems and sends them to monitoring tools for analysis. It's the data feed for observability.
Under the hood
OpenTelemetry standardizes its collection; the raw signal behind monitoring and debugging.
Examples
Metrics/logs/traces, OpenTelemetry, monitoring data, instrumentation.
Think of it like...
Like sensors on a spacecraft beaming back readings to mission control.
