- ACL based on Kubernetes namespaces/workloads/pods.
Logs:
- Container logs enriched with Kubernetes metadata;
- Host logs;
- Multi-line logs;
- Flexible field extraction;
- At least once logs delivery guarantee;
Metrics:
- Metrics are correlated with Logs;
- Host/Pods/Container/Process Metrics;
- Prometheus metrics, control plane metrics (etcd cluster, api servers, controllers, schedulers, kubelets)

Monitoring Kubernetes is a solution for monitoring Kubernetes clusters in Splunk Enterprise and Splunk Cloud. We provide a collector, explicitly built for Kubernetes, that forwards data from the clusters to Splunk software. We created dashboards that allow you to monitor your containerized applications and clusters in Splunk Enterprise or Splunk Cloud.
Product Benefits
- Built for Kubernetes. Outcold Solutions provides ready-to-use deployments, which helps you start monitoring your clusters in under 10 minutes.
- Diagnose performance of your applications using pre-built Splunk Certified Application.
- Leverage Splunk Users and Roles Control Access to set up project or cluster level ACL.
Use Cases
- Application Monitoring: see detailed metrics from containers and processes, including performance metrics, utilization metrics, and security insights. Use prebuilt Splunk dashboards for a comprehensive overview.
- Log Aggregation: aggregate logs from containers, applications, and servers in Splunk Enterprise or Splunk Cloud. Use flexible mappings for filtering logs enriched with container metadata, correlate logs with metrics, and leverage Splunk capabilities for analyzing logs.
- Cluster Health monitoring: diagnose issues with the clusters by looking at historical events and monitoring allocations and cluster capacity.
