C-Alerts

This document illustrates the procedure and steps to enable calert. The calert uses the Alertmanager webhook receiver to receive alerts payload and push this data to the Google Chat webhook endpoint. Setting up an alerting system in Kubernetes is vital for proactive issue detection, fault isolation, resource optimization, capacity planning, SLA enforcement, and security monitoring. It helps teams detect problems early, troubleshoot efficiently, optimize resources, plan for scalability, maintain service levels, and enhance security.
