planifest Observability Metrics
Overview
Use this skill to define metrics that reflect real reliability and business impact, not vanity signals.
Scope Boundaries
- Use this skill when the task matches the trigger condition described in
description. - Do not use this skill when the primary task falls outside this skill's domain.
Shared References
- Metric cardinality and SLI rules:

Templates And Assets
- Metrics taxonomy template:

- Metrics quality checklist:

Inputs To Gather
- Service health objectives and user-impact expectations.
- Capacity and performance decision needs.
- Current metric set and cardinality risks.
- Dashboard and alert consumer requirements.
Deliverables
- Metrics taxonomy and ownership mapping.
- SLI-aligned metric set.
- Dashboard/alert readiness evidence.
Workflow
- Define metric taxonomy in
assets/metrics-taxonomy-template.csv. - Apply SLI/cardinality rules from
references/metric-cardinality-and-sli-rules.md. - Validate coverage and quality with
assets/metrics-quality-checklist.md. - Tune labels and aggregation for operability.
- Publish metric governance and maintenance plan.
Quality Standard
- Metrics support reliability and capacity decisions.
- Label strategy avoids high-cardinality failure.
- Ownership and operational usage are explicit.
Failure Conditions
- Stop when key health indicators are missing or misleading.
- Stop when cardinality makes metrics operationally unstable.
- Escalate when metric gaps block incident response.
