This guide focuses on AI anomaly detection for production systems, with practical trade-offs for reliability, security, and cost.
Pastling a CloudWatch screenshot into chat is not observability. Anomaly copilots should call metrics/logs APIs as tools, reason over structured series, and propose hypotheses with links back to graphs.
⚡ TL;DR: Tools for GetMetricData / PromQL, not pixels. Baseline vs deploy markers. Never auto-remediate from a single spike without policy. Cite query + time range in every answer.
AI anomaly detection: production guidance
python
Correlate with deploy events (EventBridge/CI) before blaming “the database.”
# ✅ Metrics as tools
TOOLS = [
{
"name": "get_metric",
"input_schema": {
"type": "object",
"properties": {
"namespace": {"type": "string"},
"metric": {"type": "string"},
"stat": {"type": "string"},
"period_s": {"type": "integer"},
"start": {"type": "string"},
"end": {"type": "string"},
},
"required": ["namespace", "metric", "start", "end"],
},
}
]
python
❌ Autonomous def annotate_deploys(series, deploys):
return {
"points": series,
"deploys": [d for d in deploys if series.start <= d.ts <= series.end],
}
scale_out from one noisy datapoint.
Failure modes
Seasonality and deploy noise create false incidents. Require at least two independent signals (metric + log signature) before suggesting remediation. Weekend baselines differ — segment by day-of-week in tools.Closing checklist
- [ ] Metrics/logs tools with IAM least privilege
- [ ] Deploy markers in context
- [ ] Answers must include query + window
- [ ] Suggest-only remediations by default
- [ ] Eval on historical incidents, not synthetic sine waves only
