Tanzu Service Mesh provides summary information about the infrastructure of each onboarded cluster (its nodes, services, and service instances) and about each global namespace (its clusters, services, and service instances). You can also observe key infrastructure and service metrics and examine the connections between the services in a service topology graph.

You can access the summary infrastructure information, metrics, and service topology graphs from the Home page of the Tanzu Service Mesh Console. You can use this information and metrics to monitor the state of your infrastructure and the performance of your services.

Procedure

  1. In the navigation panel on the left side of the Tanzu Service Mesh Console, click Home.
    The metrics bar at the top of the Home page displays a summary of infrastructure and service metrics. The metrics are aggregated across your entire cluster infrastructure and services.

  2. To control which metrics are displayed on the metrics bar, click Metric Settings and select the check box next to each metric that you want displayed.
  3. View the summary information for your clusters and the topology graph for the services deployed on each cluster.
    1. On the Fabric Overview tab, click Clusters to view the cards for the clusters onboarded to Tanzu Service Mesh.
      Note:

      You can specify the time period for which to display data by selecting a period in the Data drop-down menu. This is a global setting and applies not only to the data on the Home page but also to the data on the other pages of Tanzu Service Mesh.

      The following image shows an example of a cluster card.



      A cluster's card displays the number of nodes, services, and service instances in the cluster and a minimized service topology graph.

    2. Point to the cluster name to see a summary card with the key metrics and details about the cluster.
    3. Click the cluster name to view the details page for the cluster.
    4. Click the minimized graph in the cluster card to view the detailed service topology graph.


      The graph shows the following information:

      • All the connected services that are deployed on the cluster. You can select to view all the services on the cluster or the services that belong to a specific namespace.

        • In the upper-right corner of the page, in the Show drop-down menu, select All Services or a namespace.

      • The connections between the services. Lines represent inbound and outbound service traffic. Tanzu Service Mesh tracks and reflects the state of communication between the services for the time period selected in the Data drop-down menu (for example, Last 30 minutes). If two services don't communicate at a specific point in time, no line is shown between those services in the graph.

      • The metrics for the services (such as requests per second). You can specify which metrics are displayed by clicking Settings in the upper-right corner and selecting the check box next to each metric you want displayed.

  4. View the information and metrics for a service shown in the graph.
    1. To view a card with the details and metrics about the service, point to the name of a service in the graph.
    2. To view the details page for the service, click the service name.
  5. (Optional) To reposition the service nodes in the graph for better viewing, drag them.
  6. (Optional) To zoom in and zoom out of the graph or make it fit into the page width, use the buttons in the upper-right corner.
  7. View the summary information for the global namespaces and the service topology graph for the services in each global namespace.
    1. On the Fabric Overview tab, click Global Namespaces to view the cards for the global namespaces created in Tanzu Service Mesh.


      A global namespace card displays the number of clusters, services, and service instances in the global namespace and a minimized service topology graph.

    2. Click the name of the global namespace to view its details page.
    3. Click the minimized graph in the global namespace card to view the detailed services topology graph.

      The graph shows the following:

      • All the services that are connected within the global namespace. Point to the name of a service in the graph to view a summary card with the details and metrics about the service. Click the service name to view the details page for the service.

      • The intracluster and cross-cluster connections between the services. Lines represent inbound and outbound service traffic. The topology graph in the image above shows the services from two clusters in a global namespace. The shopping service in one cluster communicates with the catalog service in the other cluster. Tanzu Service Mesh tracks and reflects the state of communication between the services for the time period selected in the Data drop-down menu (for example, Last 30 minutes). If two services don't communicate at a specific point in time, no line is shown between those services in the graph.

      • The metrics for the services (such as requests per second). You can specify which metrics are displayed by clicking Settings in the upper-right corner and selecting the check box next to each metric you want displayed.

    4. (Optional) To reposition the service nodes in the graph for better viewing.
    5. (Optional) To zoom in and zoom out of the graph or make it fit into the page width, use the buttons in the upper-right corner.
