About the Gloo UI

  • Gloo Gateway dashboard: Use the Gloo UI dashboard to quickly review the health of your Gloo Gateway setup, and any insights that were detected. If you use the Gloo UI in a multicluster setup, you can also review the health of the Gloo management server and agents.
  • Insights: The Gloo UI comes with an insights engine that automatically analyzes your Gloo Gateway setup for health issues. These issues are shared in the UI along with recommendations to harden your Gloo Gateway setup. The insights give you a checklist to address issues that might otherwise be hard to detect across your environment. For more information, see Insights.
  • Traffic resource overview: Review the Gateways, routes, policies, and destinations that are set up in your environment and the traffic management rules that you applied to them.
  • Security and compliance: The Dashboard and Security Insights pages of the Gloo UI can help you review the overall security posture of your setup, including insights and recommendations regarding your certificates, encrypted traffic, FIPS compliance, and more.
  • Drill into apps and services: Review what services can communicate with other services and how traffic between services is secured.
  • Visualize and monitor metrics: With the built-in Prometheus integration, the Gloo UI has access to workload-specific metrics, such as the number of requests that were received for a workload. This data is visualized in the Gloo UI graph.

Inventory

The Inventory section provides an at-a-glance look at the health of registered clusters and discovered services that make up your Gloo Gateway environment.

Clusters

On the Clusters page, review details of the cluster where Gloo Gateway is installed, such as insights, the health of the Gloo Gateway control and data planes, relay certificate information (in multicluster setups only), and applied routes, gateways, destinations, and policies.

In a multicluster setup, you can review the details of each cluster that you registered with the Gloo management plane.

On the Clusters page, review details of the cluster where Gloo Gateway is installed. In a multicluster setup, you can review the details of each cluster that you registered with the Gloo management plane.

  1. To filter clusters by the cluster’s installation health, click the Healthy and Unhealthy buttons. You can also use the Sort by Name dropdown or the search bar to filter clusters by name.

  2. Click More Details to see a more detailed dashboard for the cluster. This dashboard can help you find errors in your Gloo and Istio setups. Note that if you run multiple versions of Istio within the same cluster, you can click each version in the Version tab to see its details.

Traffic

The Traffic section provides an overview of deployed Gateways, routes, policies, and destinations.

Security

Security insights

The Dashboard and Security Insights pages of the Gloo UI can help you review the overall security posture of your setup, including insights and recommendations regarding your certificates, encrypted traffic, FIPS compliance, and more.

Certificates

View a list of all Istio and relay certificates in your environment. This list provides the Filter by expiration… dropdown to filter certificates by validity status, and the Filter by type… dropdown to filter certificates by type, such as Istio root or intermediate.

To view the details of a certificate, such as the issue details, total validity period, and fingerprints, click Details. On the certificate details page, you can review general information, such as the common name and organization the certificate is issued to, and check the validity period and fingerprints of the certificate.

Observability

The Gloo UI consumes telemetry data from Prometheus and Jaeger and visualizes this data in the Observability section.

Graph

The Gloo UI includes a Graph page to visualize the network traffic that reaches the services in your cluster.

Layout settings

Layout settings:

  • Animations: Change the paths between nodes from a directional animation to a solid line.
  • Mutual TLS: If you use an Istio service mesh alongside your Gloo Gateway installation, toggle the lock icons along paths between node that are mTLS encrypted.
  • TCP: Review TCP traffic.

Node Types displayed:
Nodes represent the application “nodes” of the graph. (Note that nodes represent your apps, not Kubernetes compute nodes.) You can toggle on and off views for the following nodes:

  • Kubernetes services
  • External services
  • Gateways

Node states displayed:
Toggle on or off idle nodes, which are nodes that do not receive traffic.

New Graph:

Legend

From the footer toolbar, click Show Legend.

Node Types describes the icons that are used for the application “nodes” of the graph. For example, a node might be a Kubernetes service, such as a gateway proxy, mesh workload, or waypoint proxy, or an external service, such as a virtual machine (VM), external workload, or Lambda function.

Node States and Edges show whether a service’s traffic behaves normally or not, as indicated by a color or icon.

Color or iconStateDescription
BlueNormalThe node sends and responds to traffic as expected.
RedDangerThe node has some sort of failure. For example, a policy might be applied to a route that blocks traffic to a service.
YellowWarnThe node has some sort of degraded traffic. For example, a policy might be applied to a route that rate limits traffic to a service. Most of the requests are successful, but some are not.
GrayIdleThe node does not yet accept or send traffic. For example, the deployment might be pending.
Dashed, black lineL7The traffic between nodes is sent over Layer 7 (application). For this traffic, you can apply L7 HTTP/HTTPS policies that are supported in Gloo Mesh Enterprise, Gloo Mesh Gateway, and Gloo Gateway only.
Colorful trianglesFailure, Healthy, Degraded, or IdleThe connection is in a state of failure, healthy, degraded, or idle, depending on the color. Try describing the resources in your cluster to troubleshoot further.
Blue lock iconmTLS appliedService isolation is enabled for the traffic, with communication secured via mTLS. You can change service isolation settings via an access policy for a specific destination, or for the entire workspace via the workspace settings.
Istio iconEnforced by IstioThe traffic connection is enforced by Istio.
