StackState Self-hosted v4.5.x

This page describes StackState v4.5.x. The StackState 4.5 version range is End of Life (EOL) and no longer supported. We encourage customers still running the 4.5 version range to upgrade to a more recent release.

Go to the documentation for the latest StackState release.


The OpenShift integration is used to create a near real-time synchronization of topology and associated internal services from an OpenShift cluster to StackState. This StackPack allows monitoring of the following:

  • Workloads

  • Nodes, pods, containers and services

  • Configmaps, secrets and volumes

OpenShift is a StackState core integration.

The OpenShift integration collects topology data in an OpenShift cluster as well as metrics and events.

  • Data is retrieved by the deployed StackState Agents and then pushed to StackState via the Agent StackPack and the OpenShift StackPack.

  • In StackState:

    • Topology data is translated into components and relations.

    • Tags defined in OpenShift are added to components and relations in StackState.

    • Relevant metrics data is mapped to associated components and relations in StackState. All retrieved metrics data is stored and accessible within StackState.

    • Events are available in the StackState Events Perspective and listed in the details pane of the StackState UI.



The following prerequisites are required to install the OpenShift StackPack and deploy the StackState Agent and Cluster Agent:

  • An OpenShift Cluster must be up and running.

  • A recent version of Helm 3.

  • A user with permissions to create privileged pods, ClusterRoles, ClusterRoleBindings and SCCs:

    • ClusterRole and ClusterRoleBinding are needed to grant StackState Agents permissions to access the OpenShift API.

    • StackState Agents need to run in a privileged pod to be able to gather information on network connections and host information.


Install the OpenShift StackPack from the StackState UI StackPacks > Integrations screen. You will need to provide the following parameters:

  • OpenShift Cluster Name - A name to identify the cluster. This does not need to match the cluster name used in kubeconfig, however, that is usually a good candidate for a unique name.

If the Agent StackPack is not already installed, this will be automatically installed together with the OpenShift StackPack. This is required to work with the StackState Agent, which will need to be deployed on each node in the OpenShift cluster.

Deploy the StackState Agent and Cluster Agent

For the OpenShift integration to retrieve topology, events and metrics data, you will need to have the following installed on your OpenShift cluster:

  • StackState Agent V2 on each node in the cluster

  • StackState Cluster Agent on one node

  • kube-state-metrics

➡️ Deploy StackState Agents and kube-state-metrics.

To integrate with other services, a separate instance of the StackState Agent should be deployed on a standalone VM. It is not currently possible to configure a StackState Agent deployed on an OpenShift cluster with checks that integrate with other services.


To check the status of the OpenShift integration, check that the StackState Cluster Agent (cluster-agent) pod and all of the StackState Agent (cluster-agent-agent) pods have status ready.

❯ kubectl get deployment,daemonset --namespace stackstate

NAME                                                 READY   UP-TO-DATE   AVAILABLE   AGE

Integration details

Data retrieved

The OpenShift integration retrieves the following data:


The OpenShift integration retrieves all events from the OpenShift cluster. The table below shows which event category will be assigned to each event type in StackState:


The OpenShift integration makes all metrics from the OpenShift cluster available in StackState. Relevant metrics are automatically mapped to the associated components.

All retrieved metrics can be browsed or added to a component as a telemetry stream. Select the data source StackState Metrics and type openshift in the Select box to get a full list of all available metrics.


The OpenShift integration retrieves components and relations for the OpenShift cluster.


The following OpenShift topology data is available in StackState as components:


The following relations between components are retrieved:

  • Container → PersistentVolume, Volume

  • CronJob → Job

  • DaemonSet → Pod

  • Deployment → ReplicaSet

  • Job → Pod

  • Ingress → Service

  • Namespace → CronJob, DaemonSet, Deployment, Job, ReplicaSet, Service, StatefulSet

  • Node → Cluster relation

  • Pod → ConfigMap, Container, Deployment, Node, PersistentVolume, Secret, Volume

  • ReplicaSet → Pod

  • Service → ExternalService, Pod

  • StatefulSet → Pod

  • Direct communication between processes

  • Process → Process communication via OpenShift service

  • Process → Process communication via headless OpenShift service


The OpenShift integration does not retrieve any traces data.


All tags defined in OpenShift will be retrieved and added to the associated components and relations in StackState.

REST API endpoints

The StackState Agent talks to the kubelet and kube-state-metrics API.

The StackState Agent and Cluster Agent connect to the OpenShift API to retrieve cluster wide information and OpenShift events. The following API endpoints used:

For further details, refer to the OpenShift API documentation (openshift.com).

Component actions

A number of actions are added to StackState when the OpenShift StackPack is installed. They are available from the Actions section on the right of the screen when an OpenShift component is selected or from the component context menu, displayed when you hover over an OpenShift component in the Topology Perspective

Details of installed actions can be found in the StackState UI Settings > Actions > Component Actions screen.

OpenShift views in StackState

When the OpenShift integration is enabled, the following OpenShift views are available in StackState for each cluster:

  • OpenShift - Applications -

  • OpenShift - Infrastructure -

  • OpenShift - Namespaces -

  • OpenShift - Workload Controllers -

Open source

The code for the StackState Agent OpenShift check is open source and available on GitHub at:


Troubleshooting steps for any known issues can be found in the StackState support Knowledge base.


To uninstall the OpenShift StackPack, go to the StackState UI StackPacks > Integrations > OpenShift screen and click UNINSTALL. All OpenShift StackPack specific configuration will be removed from StackState.

To uninstall the StackState Cluster Agent and the StackState Agent from your OpenShift cluster, run a Helm uninstall:

helm uninstall <release_name> --namespace <namespace>

# If you used the standard install command provided when you installed the StackPack
helm uninstall stackstate-cluster-agent --namespace stackstate
