## TL;DR

Monitoring and observability combine reliability targets, golden-signal monitoring, and telemetry signals such as traces, metrics, logs, and events.

## Core Explanation

The repaired entry replaces unsupported future observability surveys with Google SRE material and OpenTelemetry documentation. The claims now map directly to monitoring signals, service level objectives, and telemetry signal categories.
