## TL;DR

Grafana Loki LogQL and Grafana alert rules let agents connect log evidence to the rule that paged or notified a team.

## Core Explanation

Loki evidence is label-scoped. An agent needs the stream selector, time range, tenant, data source, parser pipeline, line filters, and example log lines before interpreting a spike or outage. Alert rules add the evaluation logic that turned those logs or metrics into an actionable state.

For incident work, preserve the LogQL query, alert rule UID, evaluation interval, threshold expression, folder, data source UID, notification policy, silence state, and matching labels. Without that context, an agent may confuse raw log search results with the alert condition that actually fired.
