I'm looking for recommendations on a solid monitoring and alerting setup for Kubernetes. What tools work best together? I've heard about Prometheus and Grafana, but I'm curious about how to integrate alerts effectively. Any suggestions for alerting systems that pair well with these tools?

A popular combination is using Prometheus with Grafana for monitoring, and then integrating something like PagerDuty for alerting. You just need to set up Prometheus to send its metrics to PagerDuty, which helps you manage alerts effectively. Some folks also use OpenTelemetry (otel) to gather additional metrics, giving you insights into things like CPU and RAM usage automatically.
Is PagerDuty really better than using Alertmanager from kube-prometheus-stack?
