Monitor a Global Resiliency Group¶
Overview¶
When your application services are connected to a Global Resiliency Group, you can monitor the status and activity of each Wide IP/FQDN.
Note: This release supports one FQDN/ Wide IP per Global Resiliency Group
For general information about the application service topology, see How to: Monitor application service health, configuration, and performance.
Prerequisites¶
Ensure you have created and deployed your Global Resiliency Group to one or more BIG-IP Next instances.
To view health and availability details, an application service must be deployed to at least one BIG-IP Next instance and receiving traffic.
To manage application services, you must have Administrator, Application Manager, Instance Manager user credentials. Users with Auditor credentials have read-only access to all application service information. For more information about user roles, see How to: Assign standard roles to users.
Availability status¶
Health status of the instances connected to your Global Resiliency Group are defined by the availability the endpoints connected to the selected Wide IP or FQDN.
The status associated with each instance connected to a Wide IP or FQDN is as follows:
Blue - The availability of one or more endpoint’s status is pending.
Green - All endpoints or pools to the DNS server are availabe
Yellow - One or more endpoints are either rate limited or are unavailable
Red - All endpoints to the DNS server are unavailable
Gray - Checking endpoint status is not authorized
Reviewing a Global Resiliency Group¶
Use the following procedure to review a single application service.
Log in to BIG-IP Next Central Manager, click the Workspace icon, and then click Applications.
Select the Name of the application service with a Global Resiliency Group.
BIG-IP Next Central Manager opens the application service panel.Select the eye icon to the right of the FQDN component. The Properties panel for the Global Resiliency Group opens. You can view the status of each instance the hosts the Global Resilency Group. Variation of availability status among the instances can indicate an issue with the availability of an instance’s pool members.
To monitor the number of queries received (overall) to the Global Resiliency Group, select Data Metrics from the panel menu. The panel displays the number of queries per second for the Global Resiliency Group over time. You can adjust the time period by selecting the drop down list above the chart.
Result¶
Monitor or manage the Global Resiliency Group on your application services. See the image below that demonstrates how to review an application service with a Global Resiliency Group deployed to two different instances.
