Health Check

Mission Control integrates with Grafana through its underlying data sources.

---

Health Check

Use cases:

• Monitor Prometheus metrics that power your Grafana dashboards
• Validate dashboard data sources are accessible and returning data
• Alert when metrics used in critical dashboards breach thresholds
• Check that Grafana's backend services (Prometheus, Elasticsearch, etc.) are healthy

Prometheus Data Source

While Mission Control doesn't have a direct Grafana health check, you can monitor the data sources that power your Grafana dashboards.

grafana-prometheus-check.yaml
apiVersion: canaries.flanksource.com/v1
kind: Canary
metadata:
  name: grafana-data-source
spec:
  interval: 60
  prometheus:
    - name: grafana-prometheus
      url: http://prometheus:9090  # Same Prometheus used by Grafana
      query: up{job="grafana"}
      test:
        expr: results[0] == 1

Elasticsearch Data Source

grafana-elasticsearch-check.yaml
apiVersion: canaries.flanksource.com/v1
kind: Canary
metadata:
  name: grafana-logs
spec:
  interval: 60
  elasticsearch:
    - name: grafana-elasticsearch
      url: http://elasticsearch:9200
      index: logs-*
      query: |
        {
          "query": {
            "range": {
              "@timestamp": { "gte": "now-5m" }
            }
          }
        }
      results: 1

Grafana HTTP Endpoint

grafana-api-check.yaml
apiVersion: canaries.flanksource.com/v1
kind: Canary
metadata:
  name: grafana-health
spec:
  interval: 30
  http:
    - name: grafana-api
      url: http://grafana:3000/api/health
      responseCodes:
        - 200
      responseContent:
        jsonPath:
          path: $.database
          value: ok

Dashboards

Mission Control ships with pre-built Grafana dashboards for monitoring health checks and configuration scraping.

Available Dashboards

Dashboard	Description
Canary Overview	High-level view of all health checks with pass/fail rates and trends
Canary Details	Detailed metrics for individual checks including latency histograms
Config-DB Scrape	Scraper performance metrics, cache efficiency, and change rates

Installation

Enable dashboards during Helm installation:

helm install mission-control flanksource/mission-control \
  --set grafanaDashboards=true \
  --set serviceMonitor=true

This creates ConfigMaps that Grafana's sidecar can auto-discover. See Prometheus Integration for the metrics these dashboards visualize.
