Get started with host monitoring

This page provides instructions for deploying the Dynatrace Operator in host monitoring configuration to a Kubernetes cluster.

If you're interested in gaining a more comprehensive view of your environment that includes aspects such as Application observability and user experience, you should consider a full Kubernetes observability approach, such as Full-Stack observability.

Before you begin

Before installing Dynatrace on your Kubernetes cluster, ensure that you meet the following requirements:

  • Your kubectl CLI is connected to the Kubernetes cluster that you want to monitor.
  • You have sufficient privileges on the monitored cluster to run kubectl or oc commands.

Cluster setup and configuration

  • You must allow egress for Dynatrace pods (default: Dynatrace namespace) to your Dynatrace environment URL.

  • For OpenShift Dedicated, you need the cluster-admin role.

  • Helm installation Use Helm version 3.

Supported versions

See supported Kubernetes/OpenShift platform versions and distributions.

The combination of hostMonitoring and applicationMonitoring in a Kubernetes cluster in the same environment is not supported.

Installation options

Choose one of the installation methods that best suits your needs.

Dynatrace Operator version 0.8.0+

  1. Install Dynatrace Operator

    The following command works for both default installations and installations using an OCI registry.

    helm install dynatrace-operator oci://public.ecr.aws/dynatrace/dynatrace-operator \
       --create-namespace \
       --namespace dynatrace \
       --atomic \

    Edit the values.yaml sample from GitHub, and then run the install command, passing the YAML file as an argument:

    helm install dynatrace-operator oci://public.ecr.aws/dynatrace/dynatrace-operator \
       --create-namespace \
       --namespace dynatrace \
       --atomic \
       -f values.yaml

    If installCRD is set to false, you need to create the custom resource definition manually before starting the Helm installation:

    kubectl apply -f https://github.com/Dynatrace/dynatrace-operator/releases/download/v1.4.0/dynatrace-operator-crd.yaml

  2. Create secret for access token

    Create a secret named dynakube for the Dynatrace Operator token obtained in Tokens and permissions required.

    kubectl -n dynatrace create secret generic dynakube --from-literal="apiToken=<OPERATOR_TOKEN>"

  3. Apply the DynaKube custom resource

    Download the DynaKube custom resource sample for host monitoring from GitHub. In addition, you can review the available parameters or how-to guides, and adapt the DynaKube custom resource according to your requirements.

    Run the command below to apply the DynaKube custom resource, making sure to replace <your-DynaKube-CR> with your actual DynaKube custom resource file name. A validation webhook will provide helpful error messages if there's a problem.

    kubectl apply -f <your-DynaKube-CR>.yaml

  4. optional Verify deployment

    Verify that your DynaKube is running and all pods in your Dynatrace namespace are running and ready.

    > kubectl get dynakube -n dynatrace
    NAME         APIURL                                          STATUS     AGE
    dynakube     https://<ENVIRONMENTID>.live.dynatrace.com/api  Running    45s

    In a default DynaKube configuration with CSI driver, you should see the following pods:

    > kubectl get pods -n dynatrace
    NAME                                  READY   STATUS    RESTARTS        AGE
    dynakube-activegate-0                 1/1     Running   0               50s
    dynakube-oneagent-b88rn               1/1     Running   0               50s
    dynakube-oneagent-m5jm4               1/1     Running   0               50s
    dynakube-oneagent-qhd9u               1/1     Running   0               50s
    dynatrace-oneagent-csi-driver-qxfwx   4/4     Running   0               2m49s
    dynatrace-oneagent-csi-driver-xk5c4   4/4     Running   0               2m49s
    dynatrace-oneagent-csi-driver-mz6ch   4/4     Running   0               2m49s
    dynatrace-operator-7dc8dc7d8c-wmh4z   1/1     Running   0               2m59s
    dynatrace-webhook-7bb6957fb5-l8fsq    1/1     Running   0               2m59s
    dynatrace-webhook-7bb6957fb5-rqnqk    1/1     Running   0               2m59s

    As OneAgent and CSI-driver are deployed as DaemonSet you should have a OneAgent and CSI-driver pod on each node.
