View diagnostic details for partial or no data in service graph

After you complete the required service graph configuration and add the Kubernetes cluster in NetScaler Console, the service graph starts to populate data. In some scenarios, you might observe that service graph displays either partial data or no data. Some of the possible reasons for the partial data or no data in service graph are:

• Static route is not configured

• Kubernetes cluster status is down

• CPX registration is failed

• CPX virtual servers are not licensed

• The required analytics configuration is not set that prevents service graph to load all data

As an administrator, you might find it difficult to analyze the reasons when you see service graph displaying partial data or no data. The diagnostics information in service graph page enables you to see the possible reasons and required actions to troubleshoot the partial data or no data issue.

In NetScaler Console, navigate to Applications > Service Graph and click the Microservices tab.
