grafana-tst

name	grafana-tst
description	Grafana test environment specialist for metrics, logs, traces, dashboards, and alerting. Use when asked to: query Prometheus metrics, search Loki logs, analyze Tempo traces, manage dashboards, configure alert rules, or investigate issues in the test environment. Trigger keywords: grafana-tst. Do NOT use for production environment (use grafana-prd instead).
compatibility	Requires grafana-tst agent (.augment/agents/grafana-tst.agent.md) and grafana-tst MCP server.

Grafana Test Environment Skill

Agent Delegation

Delegate ALL operations to the grafana-tst agent. "Use the grafana-tst agent to complete this task."

The grafana-tst agent provisions the grafana-tst MCP server and has the required tools (list_datasources, query_prometheus, query_loki_logs, search_traces, etc.).

Description

Access Grafana test environment for observability data. Covers metrics (Prometheus), logs (Loki), traces (Tempo), profiling (Pyroscope), incident management, OnCall schedules, Sift investigations, alerting, and dashboard management. Use for development, testing, and staging workflows.

Capabilities

Metrics (Prometheus)

• Query PromQL against test Prometheus datasources
• List metric names, label names, label values, and metadata
• Query histograms and percentiles

Logs (Loki)

• Execute LogQL queries for test log retrieval
• List log label names and values
• Query log patterns and statistics
• Stream log data with filtering and parsing

Traces (Tempo)

• Find slow requests in test environment
• Analyze distributed traces

Profiling (Pyroscope)

• Fetch CPU, memory, goroutine profiles for test services
• List profile types and label values per service

Incidents & OnCall

• Create, list, and get incident details
• Add timeline notes to incidents
• List OnCall schedules, teams, users
• Get current on-call users for a schedule

Sift Investigations

• Create and retrieve automated investigations
• Find error patterns in logs
• Find slow requests across services

Alerting

• List, get, create, update, delete alert rules
• List contact points and notification policies
• List alert groups from OnCall

Dashboards

• Search, get, create, update dashboards
• Get panel queries and dashboard summaries
• Generate deeplinks to dashboards or panels
• Render panel/dashboard images (PNG)
• Create and manage annotations

Datasources

• List, get datasources by name or UID

Key Concepts

• Datasources: Named connections to backends (Prometheus, Loki, Tempo, Pyroscope). Always resolve UIDs via list_datasources before querying.
• Prometheus / PromQL: Metrics backend. Use list_prometheus_metric_names before writing PromQL to ensure valid metric names.
• Loki / LogQL: Log aggregation backend. Always call list_loki_label_names / list_loki_label_values before building LogQL queries.
• Tempo: Distributed tracing backend. Use to find slow spans and trace request paths across services.
• Dashboards: JSON-defined panels; use get_dashboard_summary for large dashboards to avoid token limits.

Workflow

1. Connectivity check — call list_datasources (with limit=1) as a lightweight probe. If it fails, stop and report: "grafana-tst MCP server is unavailable. Cannot proceed."
2. Discover datasources — resolve correct datasource UIDs using list_datasources.
3. Discover schema — list metric names, label names/values, or log labels before querying.
4. Query or manage — use query_prometheus, query_loki_logs, search_traces, dashboard/alert tools as appropriate.
5. Report — structure the response as: datasource → time range → results summary → anomalies/patterns → recommended actions.

Usage Examples

Test Metrics

grafana-tst Show CPU usage for test-api service in test environment

Log Investigation

grafana-tst Search Loki logs for errors in auth service last 1 hour

Dashboard Editing

grafana-tst Add a new panel to the test environment overview dashboard

Alert Testing

grafana-tst Create a test alert rule for high memory usage

Trace Analysis

grafana-tst Find slow requests for checkout service in test environment

Best Practices

• Always call list_datasources first to get datasource UIDs before any query
• Always call list_prometheus_metric_names before writing PromQL
• Always call list_loki_label_names / list_loki_label_values before writing LogQL
• Use query_loki_stats to check log volume before fetching raw entries
• Use get_dashboard_summary instead of get_dashboard_by_uid for large dashboards
• Do NOT search the filesystem for mcp-config.json — always route through the agent file

Limitations

• Test environment only — data does not reflect production
• Different data retention policies than production
• Write operations (create/update alerts, incidents) require appropriate permissions
• Image rendering requires Grafana Image Renderer service

Environment Isolation

CRITICAL: Never use grafana-tst and grafana-prd in the same request. Choose only one environment per query.
