An n8n workflow automation for incident management that receives monitoring alerts via Webhook, normalizes severity levels, and routes critical incidents to PagerDuty for on-call paging while posting to a Slack #ops channel. Non-critical alerts go to Slack only. All incidents are logged to Google Sheets for post-mortem analysis and uptime reporting.
