Agent Cloud Metrics and Time-Series Alerts

## TL;DR

Metrics and time-series alerts help agents distinguish real incidents from isolated log lines by showing trends, thresholds, and recent state changes.

## Core Explanation

An agent debugging production systems should gather metric name, labels, time range, aggregation, baseline, threshold, alert rule, and notification state. Raw values without units and windows can mislead; a five-minute average and a one-hour percentile answer different questions.

Metrics are strongest when correlated with logs and traces. The agent should avoid making scale or rollback recommendations from a single chart unless it can explain the time window and supporting evidence.

## Source-Mapped Facts

- OpenTelemetry documentation describes metrics as measurements captured at runtime that can be aggregated and exported. ([source](https://opentelemetry.io/docs/concepts/signals/metrics/))
- Prometheus documentation describes alerting rules as rules that allow expressions to trigger alerts. ([source](https://prometheus.io/docs/prometheus/latest/configuration/alerting_rules/))
- Amazon CloudWatch documentation describes metrics as time-ordered sets of data points. ([source](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/working_with_metrics.html))
