Module 2: Observe, monitor and troubleshoot the application

Estimated time: 15-20 min

Learning objectives

Use Calico tools to observe, monitor and troubleshoot the application.

Observability & troubleshooting tools

If you are interested in enabling collection of application layer metrics for your workloads, refer to Configure L7 logs documentation to enable application layer metrics collection.


The Dashboard view in the Enterprise Manager UI presents high level overview of what’s going on in your cluster. The view shows the following information:

  • Connections, Allowed Bytes and Packets
  • Denied Bytes and Packets
  • Total number of Policies, Endpoints and Nodes
  • Summary of CIS benchmarks
  • Count of triggered alerts
  • Packets by Policy histogram that shows allowed and denied traffic as it is being evaluated by network policies

Policies Board

The Policies Board shows all policies deployed in the cluster and organized into policy tiers. You can control what a user can see and do by configuring Kubernetes RBAC roles which determine what the user can see in this view. You can also use controls to hide away tiers you’re not interested in at any given time.

By leveraging stats controls you can toggle additional metrics to be listed for each shown policy.

The Endpoints view lists all endpoints known to Calico. It includes all Kubernetes endpoints, such as Pods, as well as Host endpoints that can represent a Kubernetes host or an external VM or bare metal machine.

Service Graph

The dynamic Service Graph presents network flows from service level perspective. Top level view shows how traffic flows between namespaces as well as external and internal endpoints.

  • When you select any node representing a namespace, you will get additional details about the namespace, such as incoming and outgoing traffic, policies evaluating each flow, and DNS metrics.
  • When you select any edge, you will get details about the flows representing that edge.
  • If you expand a namespace by double-clicking on it, you will get the view of all components of the namespace.

Flow Visualizations

The Flow Visualizations view shows all point-to-point flows in the cluster. It allows you to see the cluster traffic from the network point of view.

Kibana dashboards

The Kibana credentials were provided in the output when we joined the cluster to Calico Cloud management plane. If you didn’t save that information, refer to Authenticaion quickstart to retrieve Kibana user password.
Note that if you configure identity provider authentication, you won’t need to deal with passwords.

The Kibana components comes with Calico commercial offerings and provides you access to raw flow, audit, and dns logs, as well as ability to visualize the collected data in various dashboards.

kibana flows

Some of the default dashboards you get access to are DNS Logs, Flow Logs, Audit Logs, Kuernetes API calls, L7 HTTP metrics, and others.
