K8s monitoring

Hi DynaMights,

I'd appreciate your recommendations.

After deployment of One Agent on K8s I got the attached below image on UAT environment.

meanwhile I've performed telnet on port 9999 it works fine, Does this error seems to be security or firewall rules.

It's not containerized ActiveGate deployment.

Thanks.

Hן @Peter_Youssef

How did you deploy the OA on your K8S there are couple of options here?

Any how please check the Troubleshoot issues on Kubernetes/OpenShift

My guess is your dynatrace operator can not docker login thru your external AG for some reason that should be found in the logs

Hi @Peter_Youssef,

As far as I understand you do not have a containerized AG. Am I correct? Then why would you try to connect via a containerized AG if it is not exists?

Try to connect via the public api end point of the K8S cluster form an non containerized AG.

This will not work without a containerized AG:

I hope it helps.

Best regards,

Mizső

Thanks @Yosi_Neuman ,

I've flushed old configurations on K8s, performed the redeployment from scratch it works fine through Public K8s API.

Thanks @Mizső

I've sorted it and deployed One Agent on 3 other K8s clusters.

Hello @Yosi_Neuman , @Mizső
when you expose such a notification, what should be the action if K8s cluster admin ensures he can see namespaces, k8s services, namespaces,..etc
