Dynatrace monitoring for Kubernetes Nodes

Bhanu1 — Tue, 22 Nov 2022 19:05:38 GMT

Is there an out of box configuration in Dynatrace which can send an alert if any of the Kubernetes nodes are not in ready state or if they have "unschedulable" taints to them

Hi @Bhanu1 , starting in SaaS 1.254, you have out-of-the-box kubernetes Alerting: https://www.dynatrace.com/support/help/how-to-use-dynatrace/infrastructure-monitoring/container-platform-monitoring/kubernetes-monitoring/alert-on-kubernetes-issues#node-alerts

Check if that fits your needs.

Thank you for pointing this. We are using 1.252 right now. For this version, do you know if we can set up any custom logs and create an alert based of off that?

Hi @Bhanu1,

You can use this in 1.252 at custom events for alerting and you can create a table or top list visualization in data explorer:

builtin:kubernetes.nodes:filter(and(or(ne(node_condition_ready,True)))):splitBy():avg:auto:sort(value(avg,descending))

Best regards,

Mizső
