Kubernetes Monitoring of Cloud application

Hello,

We have followed the latest improvement about monitoring Kubernetes and definitivelly better than it used to be. Thanks 🙂

I have one question about pod/container monitoring. We use PGBouncer to connect to our Postgresql SQL Database.

I can see the pod in cloud application, i can see the CPU and the ram usage. Perfectly fine but can't get any historic data like others containers/pods.

If i click on it I get that :

But I am sure you have the historic data (cpu/ram/...) as you displayed them in the first list.

How can I get those historic data ?


Note : We have one agent on all our kubernetes nodes and we are connected with activegate to the Kubernetes API (and we are up to date on both).


Thanks,

Alexandre

So just to confirm, you have the cluster being monitored via the API connection and you have the Oneagent Operator deployed to the Node with has deployed the oneagent to the pods and containers? and these are all up to date?

-Chad

Exactly ! We deploy the oneagent with Dynatrace Operator and we are all up to date.

For PHP/Nginx Process I can see the metrics without any issue but not pgbouncer. But I don't think PGbouncer is supported in full stack.

But from my understand i should be able to see the CPU usage/Ram usage of this container/pod.

Thats correct but the containers and pods will be listed under "Hosts" in dynatrace.

-Chad

So I can see deployment in cloud application and if I click on one deployment, i will see the list of pod inside my container. But is it only true if the pod tehchology is supported by Dynatrace.


So if I sum up :

- the data of cloud applications is coming from kubernetes API (whatever the technology)

- If i click on one deployement in cloud application, the data displayed in "technology overview" come from OneAgent installed in AKS (so need to be supported by Dynatrace)


If i want to see the cpu usage/memory usage/throtthling, i need to go to each node, go to View Container.

=> But with this screen I don't have any historic (only the last 30 minutes !).

Is there any way to have history of cpu/memory/thotthling on the last 7 days for one pod or 1 container ? I though it was in the scope of all the improvement done about Kubernetes but it seems not.


That is very interesting. I would open a support ticket up as you should be able to see the historical data from since the oneagent has been installed. That current behavior is unintended.
