Alerting & On-Call
10 templates, custom PromQL rules, and 7 notification channels — in one place.
How Alerting Works
Prometheus-powered alerting with smart deduplication, context enrichment, and 7 notification channels.
From Detection to Resolution
Pending → Firing → Resolved
PromQL condition matches → Pending. Persists for evaluation window → Firing + notifications. Metric recovers → Resolved.
Acknowledge & Silence
Acknowledge stops repeat notifications. Silence mutes alerts with label matchers — ideal for maintenance windows. Both are audit-logged.
Test & Pause
Test rules against live data before saving. Pause evaluation globally during cluster upgrades to avoid notification floods.
Alert Templates Ready to Use
Start monitoring immediately. Every threshold, duration, and severity is fully customizable.
Custom PromQL Rules
Rule Editor
Write any valid PromQL expression with 6 comparison operators: > < >= <= == !=. Set evaluation duration from 1 min to 2 hours, assign severity, and scope to specific clusters or namespaces.
Test Before Deploy
Execute your PromQL query against live Prometheus data before saving. See whether the alert would currently fire — eliminating guesswork and helping you tune thresholds before they reach your channels.
7 Ways to Get Notified
Severity routing, quiet hours, rate limiting, and test delivery — built into every channel.
Severity Routing
Route Critical + High to PagerDuty, everything to Slack. Filter by cluster and namespace so teams only see their alerts.
Rate Limiting & Quiet Hours
60 notifications/hour per channel. Quiet hours suppress Low/Medium during off-hours. Critical always delivers immediately.
Test Before Save
Send a test notification through the full pipeline — verify webhook, SMTP, bot token, or integration key before going live.
