Nebius Observability Agent for Kubernetes collects workload logs (Pod logs) from your Managed Service for Kubernetes cluster and forwards them to Logging. To install the Nebius Observability Agent for Kubernetes in your Managed Service for Kubernetes cluster, follow the guide in Nebius Observability Agent for Kubernetes. By default, the agent automatically collects logs from all workloads in your cluster. After installation, logs will appear in the default bucket in Logging.
Connect Grafana® to view ingested logs within it.

​
Log collection configuration

You can customize log collection by creating a values.yaml file and updating your Nebius Observability Agent for Kubernetes installation: 
helm upgrade nebius-o11y-agent oci://cr.nebius.cloud/observability/public/nebius-o11y-agent-helm \
  --version $(curl https://nebius-o11y-agent.storage.eu-north1.nebius.cloud/nebius-o11y-agent-helm/latest-release) \
  --namespace observability \
  --values values.yaml

​
Basic log configuration

config:
  logs:
    enabled: true
    collectAgentLogs: false
    excludedNamespaces:
      - kube-system

​
Configuration options

​
Excluding namespaces

To avoid collecting logs from infrastructure or monitoring namespaces, exclude specific namespaces from the log collection: 
config:
  logs:
    enabled: true
    collectAgentLogs: false
    excludedNamespaces:
      - kube-system
      - monitoring
      - cert-manager
      - istio-system
