Hi Sebastian,

I have followed all the steps given on https://www.dynatrace.com/support/help/cloud-platforms/kubernetes/full-stack/deploy-oneagent-on-kube... for cluster monitoring . The dynatrace oneAgent is deployed on my kubernetes cluster. When I deployed php or Nodejs application on that kubernetes cluster. I can see the application process like Nodejs process in Technologies menu but it says that process must be restart.

How should I restart the process or Do I need to restart my pod ?

Regards,

S K

You should restart containers and you should be good to go 🙂

If you deployed the application before installing oneagent, you have to restart the pods.
If the application was deployed (started) after oneagent and you see the message, there is definitely an issue with the instrumentation.

Oneagent gets installed to the node as docker container. Depending on the host OS configuration (readonly root / opt filesystem on the host) there can be issues with the instrumentation as the container could not install oneagent to the host. I've seen this for example on minikube / minishift local vms.
It is difficult to tell the exact reasons without knowing the OS configuration of your nodes.
