Managing NetScaler Insight Center

May 22, 2015

The configuration tab provides the interface through which you can manage the NetScaler Insight Center virtual appliance. You can perform management activities such as modify the network configuration, update logon credentials of devices, configure user accounts, and manage client sessions. You can also restart NetScaler Insight Center and configure security settings. You can further configure mail notifications to receive emails whenever an alert is raised.

Managing ICA Sessions

You can use the ICA session timeout feature to specify the time period for which an ICA session can remain in the idle state before being terminated. By default, if there is no flow of traffic, the session remains in active state for the first 2 minutes and then moves to Idle state.

For example, if you set the ICA session timeout value to 5 minutes, a session in which there is no traffic remains active for 2 minutes and then enters the idle state. If there is still no traffic at the end of another 5 minutes, the session is terminated. If the session has any traffic during the (2+5=) 7-minute period, the session moves to active state.

To set the ICA session time out value
  1. In the navigation pane, on the Configuration tab, click System.
  2. In the System pane, under System Settings, click Change ICA Session Timeout.
  3. In the Change ICA Session Timeout dialog box, set the Session Timeout value and click OK.

Modifying the Network Configuration

Updating Logon Credentials of NetScaler appliances

If the logon credentials of a NetScaler appliance changes after it is added to the inventory, NetScaler Insight Center is not able to connect to that appliance. In the user interface, the State column in the Inventory list displays a yellow or red circle in the row that lists the appliance.

Note: There can be many other reasons for this state change. A change in logon credentials is just one of the possible causes. To resolve this issue, you must acquire information about the credential change from the administrator of the NetScaler appliance and update NetScaler Insight Center.
