How to: Monitor application service health, configuration, and performance¶
Overview¶
Application services managed on BIG-IP Next Central Manager can be monitored to ensure that traffic and service performance meets your needs.
BIG-IP Next Central Manager provides tools that provide quick information regarding the overall health of your application service, and allow you to drill down to pinpoint the pool members affected.
Each application service has an Application Service Topology, which visualizes the application service’s components (virtual servers, pools, and pool members).
The image below is of a FAST Application Service Topology with moderate health. The application service has multiple virtual servers, services, and a WAF security policy. The application service has a moderate health status due to the performance detected on a pool member.
How do I manage application service health and performance?¶
When you deploy an application service, you can monitor each component of the application service, including a pool member.
Prerequisites¶
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.
To view health details, an application service must be deployed to at least one BIG-IP Next instance and receiving traffic.
If you plan to add components to your application service, ensure objects (such as SSL certificates) are not duplicated when deploying to an instance that is already managing application services.
Reviewing an application service¶
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 that you want to edit.
BIG-IP Next Central Manager opens the application service panel.
The panel provides the Application Service Topology across all instance deployment locations.
For more information about the tools provided in the panel, see Application service panel tools
For more information about drilling down into each component in the application service, see Review application service components
Application service panel tools¶
The application service panel provides several tools to review your application service and perform changes to the current configuration. The image below marks the tools that can customize or provide summary information about the application service.
See the numbered descriptions for more information about these tools:
Health - This area summarises the overall health status of the application service in all deployment locations.
Active Alerts - The number of active alerts on the application service. You can click the bell icon to view the application service alerts and further details. See How to: Manage Alerts and Notifications on BIG-IP Next Central Manager.
Sizing icons:
- Click or scroll to enlarge the configuration map.
- Click tor scroll to reduce the size of the configuration map.
- Click to fit the full configuration map to the application service panel.Select location - Filter the information in the application service’s topology and component properties/data metrics by a specific BIG-IP Next instance location. When you select a specific instance, the details provided in each application service component will be specific to the data gathered by that instance.
Edit - Click to edit the application service’s current configuration.
Review application service components¶
The Application Service Topology provides details about how the application service’s components are connected, and each component’s current status.
In addition, you have the option to drill down into the component properties (FAST application) and data metrics. For AS3 applications you can only view the application service and its data metrics.
Review application services¶
Use the following procedure to view the Application Service Topology for a selected 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 that you want to edit.
BIG-IP Next Central Manager opens the application service panel and displays the Application Service Topology.To view only information for a specific instance, select a location from the location list located to the top left of the panel.
The Application Service’s editor opens. The editor varies depending on whether the application service is on a FAST template or AS3 declaration.
Note: If you have not selected an instance (see Select Location), the data and properties shown for each selected component will be an aggregation of all instances.
To edit the application service, click Edit on the top right of the panel.
The Application Service’s editor opens. The editor varies depending on whether the application service is on a FAST template or AS3 declaration.To view more information about the application service, virtual servers, and pools, move your cursor over the component and select the eye icon. This opens the component’s properties. You can select Data Metrics from the panel menu to view traffic to that component.
Note: Data metrics are not available for standalone pools that are not connected to a virtual server.
To view more information about pool members, select the eye icon for the pool. The pool properties lists its pool
members, their health, and IP address. You can click the name of the pool member to view its properties and data metrics.
The image below demonstrates how to view the properties of a pool and select more details for a pool member:
