Automate Kubernetes CPU Spike Alerts from Prometheus to Slack
This workflow monitors Kubernetes pod CPU usage using Prometheus and sends real-time alerts to Slack when CPU consumption exceeds a specified threshold. It efficiently groups alerts by application name to enhance clarity and reduce noise.
Designed for DevOps and SRE teams, this no-code workflow eliminates the need for Alertmanager by directly routing critical alerts into Slack. It polls Prometheus every 5 minutes, checks for CPU usage spikes, and sends structured alerts to a designated Slack channel. The workflow can be customized to monitor other metrics like memory or network usage.
