Dashboard Events

kasdev — Wed, 21 Feb 2024 08:07:21 GMT

Hello.

I share you a visual and i've a question.

This is how Dynatrace gives container events within the container group, such as process restart, process crashed. Is there a chance to see these in a single dashboard for all applications? I looked at the metrics a bit, but I could only find the number of process restarts.

Hi,

I think that is possible but only if you are using Grail + DQL. Are you in a Grail-enabled tenant?

Best regards

You can use Platform dashboards to get this info.

fetch events | sort timestamp desc | filter dt.entity.cloud_application_namespace == "CLOUD_APPLICATION_NAMESPACE-CF142217B59E0921" | filter event.kind == "DAVIS_EVENT" | fields timestamp, dt.entity.cloud_application_instance.name, dt.kubernetes.event.involved_object.kind, dt.kubernetes.event.involved_object.name, dt.kubernetes.event.message, dt.kubernetes.event.reason | limit 100

no its managed but i've find now what you said.

i was in classic dynatrace ui before but now im in latest dynatrace and i can see your fetch events screen. but i dont know how to customize these:

i guess i firstly need to change dt.entity.cloud_application_namespace

and dt.entity.cloud_application_instance.name, dt.kubernetes.event.involved_object.kind etc..

but currently i dont know if its kubernetes or openshift. i guess its openshift.

(by the way im an intern at my company so im sorry if i ask you too much:) )

Ah!!!! now it's time for you to play with DQL
K8s , EKS, AKS or Openshift doesn't matter in this context.

hello again. i read the document but i couldn't manage to find what i need.

do you know how to query events for a specific container group name?

fetch logs query works but fetch events query does not give me anything.

The best place to ask for help with DQL is the DQL forum, but let's try something like this:

fetch events | sort timestamp desc | filter startsWith(dt.kubernetes.event.involved_object.name, "cartservice-") | filter event.kind == "DAVIS_EVENT" | fields timestamp, dt.entity.cloud_application_instance.name, dt.kubernetes.event.involved_object.kind, dt.kubernetes.event.involved_object.name, dt.kubernetes.event.message, dt.kubernetes.event.reason | limit 100

Where I filter the object with a name starting with cartservice-

Hi @kasdev,

Your other post: Creating dashboard for container events from a container group - Dynatrace Community

There is another option too if it is possible to use classic dashbboard with data explorer. If you have API integration to your k8s cluster you can use the builtin:kubernetes.events with many dimensions

You can create fancy dashboard tiles, like this:

I hope it helps.

The only reason to use DQL is to have the event message.
Otherwise, your approach is the best one.

thanks for your help but unfortunately event count does not provide me what i need.

As seen in my visual, i need container events like process restart, process crashed etc..
