Alerting Configuration Checklist
Configure effective alerts without alarm fatigue.
Too many alerts is as bad as not enough. Alert fatigue leads to ignoring critical notifications.
This checklist helps you set up smart alerting that respects your team and catches real problems.
Good alerting is the difference between proactive incident management and permanent reactive mode.
Notification Channels
Choose the right channels for each situation:
- Email pour les alertes non urgentes et les rapports
- Slack/Teams pour les alertes nécessitant attention rapide
- SMS pour les alertes critiques hors heures
- Appel téléphonique pour les urgences absolues
- PagerDuty/OpsGenie pour la gestion d'astreinte
Thresholds and Conditions
Define smart triggers:
- Seuils basés sur les SLOs, pas sur des valeurs arbitraires
- Conditions de durée (alerter après X échecs consécutifs)
- Fenêtres de maintenance pour éviter les faux positifs
- Différencier warning et critical
Escalation
Plan escalation when first alert goes unanswered:
- Qui est notifié en premier (équipe on-call)
- Délai avant escalade au niveau supérieur
- Contact de dernier recours (manager, CTO)
- Procédure si personne ne répond
Réduire la Fatigue
Éviter l'alert fatigue :
- Revue mensuelle des alertes (supprimer les inutiles)
- Grouper les alertes similaires
- Implémenter la double vérification avant alerte
- Mesurer le ratio signal/bruit
Frequently Asked Questions
How many alerts is too many?
If your team regularly ignores or delays responding to alerts, that's too many. Each alert should be actionable.
Should I be alerted for every downtime?
Require confirmation (2-3 failures) to avoid transient false positives. But always alert for confirmed downtime.
How to handle scheduled maintenance?
MoniTao offers maintenance windows to temporarily suspend alerts on specific monitors.
How to test my alerting configuration?
Run a test alert via MoniTao to verify all channels work and reach the right people.
