Rules and Actions

Symptoms

• Rule state stays NORMAL when value looks out of range
• Alarm created but no Slack/email/Telegram message
• HTTP action appears to do nothing

Rules not firing

1. Rule is active and tag path matches incoming telemetry exactly
2. Detector params — windowed types need enough samples (minSamples, windowSec)
3. THRESHOLD — expression syntax; duration / PENDING state before TRIGGERED
4. GOLDEN_PROFILE — baseline record exists for the tag
5. Rule-worker running — changes propagate via datahub.rule.changed without restart

Actions not delivering

1. Channel configured (webhook URL, email to, etc.)
2. Environment variables for Slack/Telegram/SMTP if channel config is empty
3. Unconfigured channels are skipped — they do not fail the job
4. Test HTTP sink: GET /api/webhooks/test/log after triggering a test rule
