Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Monitoring & Observability Build comprehensive observability for your systems. ## The Three Pillars ### 1. Metrics (Prometheus) ```yaml # Instrument your app http_requests_total{method="GET", endpoint="/api/users", status="200"} 1024 http_request_duration_seconds{quantile="0.95"} 0.235 ``` ### 2. Logging (Loki / ELK) - Structured JSON logging - Include: timestamp, level, service, trace_id, message - Centralized log aggregation - Log levels: DEBUG < INFO < WARN < ERROR < FATAL ### 3. Tracing (Jaeger / Tempo) - Trace every request across services - Span: individual operation with timing - Distributed context propagation via trace ID headers - Sample 1-10% of production traffic ## Alerting (Alertmanager) ### Alert Severity | Severity | Response Time | Channel | |----------|--------------|---------| | Critical | Immediately | PagerDuty + SMS | | Warning | 1 hour | Slack + Email | | Info | Next day | Dashboard | ### Golden Signals (Google SRE) 1. **Latency**: Time to respond 2. **Traffic**: Requests per second 3. **Errors**: Error rate (5xx, exceptions) 4. **Saturation**: Resource utilization ## Dashboard Design (Grafana) ### Rules - 3-5 panels per row - Time series with trend lines,

What does the monitoring-observability skill do?
Prometheus, Grafana, ELK/Loki, Jaeger, metrics, logging, tracing, and alerting
How do I install it?
Run `npx skills add cosmicstack-labs/mercury-agent-skills --skill monitoring-observability --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From cosmicstack-labs/mercury-agent-skills, a repository with 364 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
