Gloo UI
Monitor the health of your service mesh and review workspace, networking, and policy configurations with the Gloo UI.
About the Gloo UI
The Gloo UI is automatically installed in the Gloo management cluster. Let's explore some of the key features that you have access to when using the Gloo UI:
- Gloo Platform overview: With the Gloo UI, you can view information about your Gloo Platform environment, such as the number of clusters that are registered with the Gloo management server and the Istio version that is deployed to them. You can also review your workspace settings and which Gloo resources you import and export to other workspaces.
- Verify service mesh configurations: The Gloo Mesh UI lets you quickly find important information about your service mesh setup, the participating clusters, and the Gloo Mesh resources that you applied to the service mesh. For example, you can review your workspace settings and which Gloo Mesh resources you import and export to other workspaces. You can also view your gateway and listener configurations and traffic policies that you applied to your service mesh routes.
- Drill into apps and services: Review what services can communicate with other services in the mesh, the policies that are applied before traffic is sent to a service, and how traffic between services is secured.
- Visualize and monitor service mesh health metrics: With the built-in Prometheus integration, the Gloo Mesh UI has access to detailed Kubernetes cluster and service mesh metrics, such as the node's CPU and memory capacity, unresponsive nodes or nodes with degraded traffic, and mTLS settings for services in the mesh. For more information about the Prometheus integration in Gloo Mesh, see Prometheus.
- OIDC authentication and authorization support: Set up authentication and authorization (AuthN/AuthZ) for the Gloo Mesh UI by using OpenID Connect (OIDC) and Kubernetes role-based access control (RBAC). The Gloo Mesh UI supports OpenID Connect (OIDC) authentication from common providers such as Google, Okta, and Auth0.
For a detailed overview of what information you can find in the Gloo UI, see Explore the Gloo UI.
To further protect the Gloo UI from unauthorized users, set up authentication and authorization (AuthN/AuthZ) for the Gloo UI by using OpenID Connect (OIDC) and Kubernetes role-based access control (RBAC). The Gloo UI supports OpenID Connect (OIDC) authentication from common providers such as Google, Okta, and Auth0. For more information, see Set up external auth for the Gloo UI.
Monitored metrics in the Gloo UI
The Gloo UI monitors and visualizes the following metrics from the built-in Prometheus server for the workloads in your cluster. You can see and work with these metrics by using the Gloo UI Graph.
istio_requests_total
: This metric is used to determine the number of total requests, successful and failed requests that were sent to your workloads.istio_request_duration_milliseconds_bucket
: To determine the latency between microservices, the Gloo UI monitors the milliseconds it takes for a request to be routed to its destination.
