View container image and tag

nc1 — Thu, 02 Oct 2025 10:32:20 GMT

Hi,

When monitoring Kubernetes using the Dynatrace operator, I would like to create a dashboard that shows the container image tag being used by our containers. So far I have not been able to find a way to get this information in Dynatrace. Is it possible to get this data?

You can achieve this by tagging your workloads with Kubernetes labels or annotations. Dynatrace automatically ingests these labels and converts them into tags, which you can then use for automated tagging rules, filtering, or assigning ownership.

Documentation: https://docs.dynatrace.com/docs/observe/infrastructure-monitoring/container-platform-monitoring/kubernetes-monitoring/leverage-tags-defined-in-kubernetes-deployments

However, in Dynatrace Managed you cannot directly display these tags on a dashboard. They are primarily useful for organizing, filtering, and assigning ownership to entities, but not as a first-class property for dashboard visualizations.

@nc1 If its the container image name you are after, you can try something like below if you are SaaS

fetch dt.entity.container_group_instance | fieldsAdd containerName = entity.name, containerImageName

Hi @nc1
I think that you need Kubernetes labels and anotations , you can get with this.

fetch dt.entity.kubernetes_service | filter contains(entity.name,"dynatrace") | fieldsAdd kubernetesLabels , kubernetesAnnotations

With that, You will be able to create a dashboards you need
I hope it helpfull 💪
