          )
        for: 5m
        labels:
          severity: critical

Contact Points (YAML provisioning)

# provisioning/alerting/contact_points.yaml
apiVersion: 1
contactPoints:
  - orgId: 1
    name: pagerduty-critical
    receivers:
      - uid: pd-receiver
        type: pagerduty
        settings:
          integrationKey: YOUR_PAGERDUTY_KEY
          severity: critical

  - orgId: 1
    name: slack-alerts
    receivers:
      - uid: slack-receiver
        type: slack
        settings:
          url: https://hooks.slack.com/services/YOUR/WEBHOOK/URL
          channel: '#alerts'
          username: Grafana
          icon_emoji: ':grafana:'
          title: '{{ template "slack.default.title" . }}'
          text: '{{ template "slack.default.text" . }}'

  - orgId: 1
    name: email-alerts
    receivers:
      - uid: email-receiver
        type: email
        settings:
          addresses: 'oncall@example.com;alerts@example.com'

  - orgId: 1
    name: webhook-alerts
    receivers:
      - uid: webhook-receiver
        type: webhook
        settings:
          url: https://your-endpoint.com/grafana-alerts
          httpMethod: POST

Notification Policies (YAML provisioning)

# provisioning/alerting/policies.yaml
apiVersion: 1
policies:
  - orgId: 1
    receiver: default-receiver
    group_by: ['alertname', 'cluster', 'service']
    group_wait: 30s
    group_interval: 5m
    repeat_interval: 12h
    routes:
      # Critical alerts → PagerDuty
      - receiver: pagerduty-critical
        matchers:
          - severity = critical
        group_wait: 10s
        group_interval: 1m
        repeat_interval: 4h

      # Platform team alerts → Slack
      - receiver: slack-alerts
        matchers:
          - team = platform
        routes:
          # Critical platform → page immediately
          - receiver: pagerduty-critical
            matchers:
              - severity = critical

      # Everything else → email
      - receiver: email-alerts
        matchers:
          - severity =~ "warning|info"

Silences

Silences suppress notifications for matching alerts without stopping evaluation.

# Via API - create a silence
curl -X POST https://grafana.example.com/api/alertmanager/grafana/api/v2/silences \
  -H 'Content-Type: application/json' \
  -d '{
    "matchers": [
      {"name": "alertname", "value": "HighErrorRate", "isRegex": false},
      {"name": "env", "value": "staging", "isRegex": false}
    ],
    "startsAt": "2024-01-01T00:00:00Z",
    "endsAt": "2024-01-01T02:00:00Z",
    "comment": "Maintenance window",
    "createdBy": "admin"
  }'

Alert Rule States

State Description
Normal Condition not met
Pending Condition met, waiting for for duration
Firing Condition met for full for duration
NoData Query returned no data
Error Query/evaluation error
Recovering Was firing, condition no longer met

SLOs

# SLO configuration (via Grafana UI or API)
# Grafana auto-generates recording rules, dashboards, and burn-rate alerts

# Generated recording rules example:
groups:
  - name: slo_availability
    interval: 1m
    rules:
      - record: slo:availability:ratio_rate5m
        expr: |
          sum(rate(http_requests_total{status!~"5.."}[5m])) by (service)
          / sum(rate(http_requests_total[5m])) by (service)

      - record: slo:error_budget:remaining
        expr: |
          (slo:availability:ratio_rate30d - 0.999) / (1 - 0.999)

# Burn rate alerts (auto-generated by Grafana SLO)
- alert: SLOBurnRateHigh
  expr: |
    slo:burn_rate:ratio_rate1h > 14.4      # 1h window, 5% budget in 1h
  for: 2m
  labels:
    severity: critical
  annotations:
    summary: "SLO burn rate critical for {{ $labels.service }}"

IRM - On-Call and Incidents

Key IRM Capabilities

  • On-Call Schedules: Rotating shifts, overrides, escalation policies
  • Alert Routing: Route from Grafana Alerting, Prometheus, Datadog, PagerDuty, etc.
  • Incident Management: Declare incidents, add participants, track tasks/timeline
  • Escalation Chains: Auto-escalate if no response after N minutes
  • Integrations: Slack, Teams, Telegram, GitHub, Jira, StatusPage

IRM Integration Sources

Source Setup
Grafana Alerting Native - configure in contact points
Prometheus Alertmanager Webhook URL from IRM
Datadog Webhook integration
PagerDuty Event integration
Jira Issue alerts
Custom Generic webhook
