Forward your Google Kubernetes Engine (GKE) logs directly to Cortex XDR using Elasticsearch Filebeat.
Ingesting logs and data requires a Cortex XDR Pro per GB license.
Instead of forwarding Google Kubernetes Engine (GKE) logs directly to Google StackDrive, Cortex XDR can ingest container logs from GKE using Elasticsearch Filebeat. To receive logs, you must install Filebeat on your containers and enable Data Collection settings for Filebeat.
After Cortex XDR begins receiving logs, the app automatically creates an Cortex Query Language (XQL) dataset using the vendor and product name that you specify during Filebeat setup. It is recommended to specify a descriptive name. For example, if you specify
kubernetes as the product, the dataset name will be
google_kubernetes_raw. If you leave the product and vendor blank, Cortex XDR assigns the dataset a name of
After Cortex XDR creates the dataset, you can search your GKE logs using XQL Search.
Install Filebeat on your containers.
For more information, see https://www.elastic.co/guide/en/beats/filebeat/current/running-on-kubernetes.html.
Record your token key and API URL for the Filebeat Collector instance as you will need these later in this workflow.
Deploy a Filebeat as a DaemonSet on Kubernetes.
This ensures there is a running instance of Filebeat on each node of the cluster.
Download the manifest file to a location where you can edit it.
curl -L -O https://raw.githubusercontent.com/elastic/beats/7.10/deploy/kubernetes/filebeat-kubernetes.yaml
Open the YAML file in your preferred text editor.

ELASTICSEARCH_ENDPOINT—Specify the API URL for your Cortex XDR tenant. You can copy the URL from the Filebeat Collector instance you set up for GKE in the Cortex XDR management console ( → → → → . The URL will include your tenant name (

ELASTICSEARCH_API_KEY—Specify the token key you recorded earlier during the configuration of your Filebeat Collector instance.
After you configure these settings your configuration should look like the following image.
Save your changes.
If you use RedHat OpenShift, you must also specify additional settings.
Deploy Filebeat on your Kubernetes.
kubectl create -f filebeat-kubernetes.yaml
This deploys Filebeat in the kube-system namespace. If you want to deploy the Filebeat configuration in other namespaces, change the namespace values in the YAML file (in any YAML inside this file) and add
After you deploy your configuration, the Filebeat DameonSet runs throughout your containers to forward logs to Cortex XDR. You can review the configuration from the Kubernetes Engine console: → → .
Cortex XDR supports logs in single line format or multiline format. For more information on handling messages that span multiple lines of text in Elasticsearch Filebeat, see Manage Multiline Messages.
After Cortex XDR begins receiving logs from GKE, you can use the XQL Search to search for logs in the new dataset.
