Monitoring Virtual Servers, Services, Servers, and Service Groups

Dec. 18, 2015

You can monitor the real-time status of virtual servers, services, servers, and service groups using the Monitoring feature of Command Center. You can also view the services and service groups bound to virtual servers.

You can further add views to monitor specific entities based on entity names, device names, protocol types, states, and health.

This topic includes the following details:

Viewing the Status of Virtual Servers

Updated: 2014-04-15

Use Command Center to monitor the real-time values of the state and health of a virtual server. You can also view the attributes of a virtual server, such as name, IP address, and type of virtual server.

To view the status of virtual servers

  1. On the Monitoring tab, in the left pane, under NetScaler, click Virtual Servers.
  2. In the right pane, under Virtual Servers, view the following statistics:
    • Device Name: Specifies the name of the device on which the virtual server is configured.
    • Name: Specifies the name of the virtual server.
    • IP: Specifies the IP address of the virtual server. Clients send connection requests to this IP address.
    • Port: Specifies the port on which the virtual server listens for client connections.
    • Type: Specifies the type of virtual server (for example, load balancing). This information is available only for virtual servers configured on NetScaler release 9.0 and later.
    • Protocol: Specifies the service type of the virtual server. For example, HTTP, TCP, and SSL.
    • State: Specifies the current state of the virtual server. For example, UP, DOWN, and OUT OF SERVICE.
    • Health: Specifies the percentage of the services that are in the state UP and are bound to the virtual server. The following formula is used to calculate the health percentage: (Number of bound UP services * 100) / Total bound services
    • Last State Change: Specifies the time elapsed (in days, hours, minutes, and seconds) since the last change in the state of the virtual server, that is, the duration of time for which the virtual server is in the current state. This information is available only for virtual servers configured on NetScaler release 9.0 and later.
    Note: You can sort the rows in ascending or descending order by clicking the column headers. For example, clicking the Device Name column header sorts the rows in order of the device names.

Viewing the Status of Servers

Configuring Views

Updated: 2015-05-28

You can add views to monitor specific entities based on entity names, device names, protocol types, states, and health. Views make it easier to monitor a large number of entities configured across your NetScaler infrastructure. For example, you can create a view to monitor virtual servers with protocol type as AAA.

The views you create are associated with your Command Center user account. If you want to assign these views to other groups of users, you must assign administrator privileges to the view.

This topic includes the following details:

  • Adding Views for Virtual Servers
  • Adding Views for Services
  • Adding Views for Service Groups
  • Modifying Views

Assigning Views

After you create a view, the view is visible only to you. If you want the same view to be visible to others, you must assign administrator privileges to the view. The administrator can then assign the view to the required group of users. Only the administrator can assign the view to other groups. After you specify administrator privileges, you no longer have permission to modify or delete the view.

If a view is modified by an administrator, the modified data is applicable to all users in the assigned groups.

You can specify administrator privileges to a view when you create the view, or you can assign them by modifying an existing view.

Example

Sam, in the engineering group, creates a view displaying all the NetScaler virtual servers that are in the unknown state. He wants the analytics group to be able to use this view to analyze the reason for the unknown state. The analytics team could create a similar view, but it might not use the same filters, and Sam's filters are uniquely effective. Sam therefore assigns administrator privileges to the view, and the administrator assigns the view to the analytics group. Both Sam and the analytics group can now access the view. Only the administrator can modify it.

To assign administrator privileges to an existing view

  1. On the Monitoring tab, navigate to NetScaler, and then to Virtual Servers, Services, Service Groups, or Servers, and then click Views.
  2. In the right pane, select the view and click Edit.
  3. On the page for modifying views, click Administrator View.

To assign views to different groups

Note: This task is applicable to administrators only.
  1. On the Monitoring tab, navigate to NetScaler, and then to Virtual Servers, Services, Service Groups, or Servers, and then click Views.
  2. In the right pane, select the view and click Assign View.
