Grafana is an open source interactive data-visualization platform that allows you to see data via charts and graphs that are unified into one dashboard.

Cilium dashboard

Cilium dashboard

When you add Cilium, Hubble, and eBPF-specific metrics to the Gloo telemetry pipeline, you can import the pre-built Cilium dashboard to Grafana. This dashboard provides the following key features that can help you monitor the health of your Cilium components and the workloads in your cluster:

  • Cilium agent and operator resource consumption and latency: Gain insights into the state of the Cilium CNI components, such as the Cilium agent and the Cilium operator. For example, you can monitor the average CPU and memory consumption of the Cilium agent, the number of Cilium API calls, their latency and API return codes.
  • Layer 3 BPF metrics: Monitor the system-wide memory consumption of eBPF maps, the number of system calls, their latency, and IP allocation operations.
  • Network traffic: Track incoming and outgoing network packets that were successfully processed or dropped for Cilium-managed Kubernetes pods.
  • Network policies: Monitor the number of requests that were allowed or prohibited by network policies, and the endpoints that are labeled by policy enforcement status.
  • Cilium endpoints: Review the number of endpoints that Cilium monitors and their status.

The Cilium dashboard is not automatically set up when you install Gloo Mesh Enterprise. To access the dashboard, you must follow these steps:

  1. Set up and access Grafana.
  2. Import the Cilium dashboard.
