grafana

Grafana

Query and manage Grafana monitoring dashboards, alert rules, and data sources via HTTP API.

Setup

Configure your Grafana instance:

Variable	Description	Required
GRAFANA_URL	Your Grafana server URL (e.g., https://grafana.example.com)	Yes
GRAFANA_TOKEN	API Key (Settings → API Keys, viewer or editor role)	Yes

Authentication: curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" "$GRAFANA_URL/api/..."

Customize the following for your organization:

• Folder structure: How dashboards are organized (by team, region, service, etc.)
• Tag conventions: What tags are used for filtering (region, environment, service type)
• Alert naming: Your alert naming pattern (e.g., {Service} {Metric} {Condition} [{env}])
• Key dashboards: Which dashboards to check after deployments

Rules

Dashboard Operations

• Search first, then detail: Use search API with tags/query to narrow scope, then fetch by uid
• Never delete production dashboards — archive by moving to an Archive folder
• Write operations require user confirmation before execution (create/modify dashboards, alert rules)

Common Workflows

Find a Dashboard:

curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/search?query=<keyword>&tag=<tag>&type=dash-db" \
  | jq '.[] | {uid, title, folderTitle}'

Get Dashboard Details:

curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/dashboards/uid/<uid>" \
  | jq '.dashboard.panels[] | {title, type}'

Check Active Alerts:

curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/alerts?state=alerting"

List Data Sources:

curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/datasources" \
  | jq '.[] | {id, name, type, url}'

Search by Folder:

curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/search?folderIds=<folder_id>&type=dash-db"

Post-Deployment Checks

After each deployment, check key dashboards for:

• Error rate changes (before vs after deployment)
• Latency P95/P99 trends
• Consumer lag (if using message queues)
• Connection counts (TCP/WebSocket)
• Log level distribution (error/warn spikes)

Alert Troubleshooting

1. GET /api/alerts?state=alerting — list all firing alerts
2. Identify the dashboard and panel from the alert
3. Read the PromQL expression from the panel
4. Query Prometheus directly to understand the data
5. Check recent deployments or config changes as potential cause

Examples

Bad

# Delete a production dashboard (never delete, archive instead)
curl -X DELETE "$GRAFANA_URL/api/dashboards/uid/abc123"

# Fetch all dashboards without filtering (use search first)
for uid in $(curl ... /api/search | jq -r '.[].uid'); do
  curl ... /api/dashboards/uid/$uid
done

Good

# Search dashboards by tag
curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/search?tag=production&type=dash-db" \
  | jq '.[] | {uid, title, folderTitle}'

# Check active alerts
curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/alerts?state=alerting"

# Get alert details for troubleshooting
curl -s -H "Authorization: Bearer $GRAFANA_TOKEN" \
  "$GRAFANA_URL/api/alerts/<alert_id>"
