Basic Information

What is NetScaler Insight Center?
NetScaler Insight Center is a reporting and monitoring tool that collects AppFlow traffic generated across NetScaler ADCs or CloudBridge appliances and generates reports.
What are the main components of NetScaler Insight Center support?
NetScaler Insight Center combines Web Insight for HTTP analytics and HDX Insight for ICA visibility.
Is NetScaler Insight Center hardware or software?
NetScaler Insight Center is a virtual appliance designed to be installed on a XenServer hypervisor, VMware ESX, or Microsoft Hyper-V.
What configurations do I have to verify on the XenApp or XenDesktop server?
On a XenApp or XenDesktop server running version 6.5, if you require RTT calculations for idle connections, then make sure that the ICA round trip calculations for Idle Connections option is enabled for NetScaler Insight Center. If the option is disabled, enable it and execute the gpupdate command.
Note: The RTT calculation interval should be less than 60 seconds. By default, it is set to 30 seconds.
What type of reports does NetScaler Insight Center generate?
NetScaler Insight Center generates analytical reports, from which users can view the performance of applications, identify problem areas, and intelligently troubleshoot issues with performance and access.
Is there any physical connection required between the NetScaler appliances to be monitored and the XenServer?
No.
How do I specify the devices to be monitored by NetScaler Insight Center?
You add the devices to the NetScaler Insight Center Inventory list. To do so, you have to specify the IP address, user name, and password of the device.
After I add the device, does NetScaler Insight Center start collecting information?
No. You must first enable AppFlow on CloudBridge devices or on the applications managed by the NetScaler appliance. When you enable AppFlow on NetScaler ADCs, you should specify an expression to identify the traffic for which the NetScaler appliance will generate AppFlow records.
Should I access the individual NetScaler appliance for enabling AppFlow?
No. All configuration is done from the NetScaler Insight Center user interface, which lists the virtual servers for a specific NetScaler appliance. In addition, for HDX Insight, ICA ports can be configured at a global level so that traffic flowing to these ports is inspected and Appflow records are generated.
Are all virtual servers on a NetScaler appliance listed for enabling AppFlow?
Currently, the NetScaler Insight Center user interface lists the load balancing, content switching, VPN, and NetScaler Gateway virtual servers for enabling AppFlow.
Should the virtual server be UP when you enable AppFlow on it?
Yes. To verify that the virtual server is UP, you can view its operational status on the NetScaler Insight Center user interface.
After I integrate NetScaler Insight Center with Desktop Director, Desktop Director does not display any records in my Chrome browser. What should I do?
If Desktop Director does not display any records, make sure that both Desktop Director and NetScaler Insight Center have either HTTPS or HTTP enabled. For details about NetScaler Insight Center configurations, see "Configuring Security Settings" in Managing System Settings.

Q. How do I attach an additional disk to NetScaler Insight Center?

To attach an additional disk to NetScaler Insight Center:

  1. Shut down the NetScaler Insight Center virtual machine.
  2. In the hypervisor, attach an additional disk of the required disk size to NetScaler Insight Center virtual machine.
    For example, for a NetScaler Insight Center virtual machine of 120 GB, if you want to increase its disk space to 200 GB, you then need to attach a disk space of 200 GB instead of 80 GB. Newly attached 200 GB of disk space will be used to store Database data, NetScaler Insight Center log files. The existing 120 GB disk space will be used to store core files, Operating system log files, and so on.
  3. Start the NetScaler Insight Center virtual machine. 

NetScaler Appliance Specifications

Is there any specification for a NetScaler appliance to be monitored?
Yes, only NetScaler nCore appliances running version 9.3 or later software can be monitored. In addition, for HDX Insight, only Netscaler appliances running version 10.1 software can be monitored.
Can I add NetScaler appliances running different licenses?
Any nCore appliances running software version 9.3 or later build can be monitored by NetScaler Insight Center. However, the full set of counters and reports are generated only for Platinum-licensed NetScaler 10.1 appliances.
Can NetScaler Insight Center monitor a NetScaler high availability setup?
Yes.NetScaler Insight Center can monitor appliances in a high availability setup. Citrix recommends that you add both the appliances (primary and secondary) to the NetScaler Insight Center appliance. When the primary appliance fails, the secondary appliance generates the performance reports. You do not have to explicitly enable AppFlow on the secondary appliance.
Can a NetScaler cluster be monitored by NetScaler Insight Center?
No. NetScaler Insight Center does not support cluster nodes.

Can I use a CloudBridge VPX to demonstrate how NetScaler Insight Center collects reports from CloudBridge appliances?

NetScaler Insight Center does not support CloudBridge VPX.

However, if you want to use CloudBridge VPX for demonstration purpose, make sure that the CloudBridge VPX has primary and accelerated pairs (apA) configured.

For details, see "Configuring Inline Mode" in CloudBrisge 7.3 Product Documentation.

What are the prerequisites to monitor CloudBridge appliances?
Before you start using NetScaler Insight Center to monitor a CloudBridge appliance, make sure that you have met the following prerequisites:
  • The NTP server must be configured on both the CloudBridge appliance and NetScaler Insight Center. To add an NTP server to NetScaler Insight Center, see Configuring Clock Synchronization. These NTP servers must be closely synchronized to each other.
  • Make sure that the CloudBridge appliances can communicate with NetScaler Insight Center by using port 4739.
  • When both NetScaler ADC and CloudBridge appliance is located in the same network path, you cannot configure a single NetScaler Insight Center to monitor both the appliances. NetScaler ADC and CloudBridge appliance should use different NetScaler Insight Center virtual appliances for generating HDX Insight reports.
  • Make sure that the CloudBridge appliance should only use the primary interface for sending Appflow records.
  • Do not configure the CloudBridge appliance at the branch office to send Appflow records to NetScaler Insight Center.
  • Verify that the CloudBridge appliance, XenApp or XenDesktop, and Receiver versions are supported by NetScaler Insight Center.
  • To monitor the CloudBridge appliance, NetScaler Insight Center must successfully discover the CloudBridge appliance.
  • Enable HDX data set on the CloudBridge appliance. To verify, on the Configuration tab, navigate to Appliance Settings > AppFlow.
  • Make sure that the Update Interval is set to one minute on the CloudBridge appliance. Also, make sure that the IP address and port values are not deleted. To verify, on the Configuration tab, navigate to Appliance Settings > AppFlow.
  • Make sure that CloudBridge ICA connections are accelerated with Disk Based Compression (DBC) policy. To verify, on the Configuration tab, navigate to Optimization Rules > Service Classes and in the right pane, expand ICA and click Edit. The Acceleration policy must be Disk.
Does the CloudBridge appliance generate AppFlow reports for non-accelerated ICA connections?

No. NetScaler Insight Center reports are generated only when CloudBridge ICA connections are accelerated with Disk Based Compression (DBC) policy.

To verify, on the Configuration tab, navigate to Optimization Rules > Service Classes and in the right pane, expand ICA and click Edit. The Acceleration policy must be Disk ICA connections. The ICA Service class policies that are not accelerated and configured with Flow Control policy, do not generate HDX Insight reports.

NetScaler insight Center does not generate reports if CloudBridge ICA connections are accelerated with flow control policy.

Does NetScaler Insight Center support Multi Stream ICA (MSI) for CloudBridge appliances?
Currently NetScaler Insight center does not support collecting data records for MSI connections.
Is the CloudBridge Plug-In supported by NetScaler Insight Center reports?

Yes. ICA connections from Plug-in-equipped systems must be accelerated with DBC compression policy.

To verify, on the Configuration tab of the CloudBridge appliance, navigate to Optimization Rules > Service Classes and in the right pane, expand ICA and click Edit. The Acceleration policy must be Disk.

Are thin clients supported by NetScaler Insight Center?

NetScaler Insight Center supports thin clients, but the client type details in the User Agent reports display incorrect values.

Can a CloudBridge datacenter appliance and NetScaler ADC be added to the same NetScaler Insight Center, present in the same datacenter location?

No. This is not supported in this release.

Can I add multiple CloudBridge datacenter appliances (present in the same datacenter location) to the same NetScaler Insight Center?

Yes.

Is the CloudBridge appliance supported with Desktop Director?

Yes. CloudBridge appliance is supported with Desktop director. However, the WAN Jitter and DC Jitter values are not supported.

Why is the DC Latency value more than ICA RTT?

Ideally ICA RTT should be greater than the sum of WAN Latency and DC latency.

If the application is not actively sending data, then it does not work as expected. This is because, the TCP RTT estimation works only on active connections. If a connection is not very active or if it is idle, the DC latency value will be more than ICA RTT or WAN Latency.

What are the limitations of using Desktop Director Plug-in for generating HDX Insight reports for CloudBridge appliances?
  • Desktop director does not correlate data across user sessions with NetScaler Insight Center, if CloudBridge generates a Replacement Session GUID (instead of using an Genuine GUID).

    To verify, on the CloudBridge appliance, navigate to Monitoring > ICA Advanced > Conn Info.

    This occurs if the customer is using an unsupported ICA Client or XenApp or XenDesktop server. For supported versions, see Supported Software.

  • Desktop Director does not support WAN Jitter and LAN Jitter values.
What are the limitations of using thin clients for monitoring CloudBridge appliances?

General Information

If I change the host name of the NetScaler appliance, will the NetScaler Insight Center inventory and Dashboard reflect the change?
Yes. NetScaler Insight Center reflects the changes every 30 minutes.
If the logon credentials of my device change, should I update that information in NetScaler Insight Center?
Yes. Fifteen seconds after the logon credentials of a device change, the NetScaler Insight Center inventory displays the state of the device as OUT-OF-SERVICE , but you can view the reports for the device. However, to continue collecting AppFlow records for the virtual servers managed by the NetScaler ADC, you must update the logon credentials in NetScaler Insight Center. For more information about updating the logon credentials in theNetScaler Insight Center, see Updating Logon Credentials of Devices.
If I update the login credentials, will the state of the device be "UP" immediately?
The state of the device in the NetScaler Insight Center inventory changes to "UP" after a few seconds.
My NetScaler appliance uses it's Subnet IP address (SNIP) as the source IP address for management access. Does NetScaler Insight Center collect data from the NetScaler appliances?

Yes. NetScaler Insight Center collects data from the NetScaler appliance. When adding the NetScaler appliance to NetScaler Insight Center Inventory, specify the SNIP address used for management access as the IP address of the appliance.

Reports

How do I view the reports?
By default, the Dashboard page displays a performance chart of the devices monitored by NetScaler Insight Center. You can click on the chart to move to the next level of information.
Are reports generated for all devices added to the NetScaler Insight Center inventory?
No. Only if you enable AppFlow on a CloudBridge appliance, or at least one virtual server in the NetScaler appliance does NetScaler Insight Center collect data from that appliance and generate reports.
How are the reports organized?
You can view reports for devices, applications, URLs, clients and servers on the Web Insight node, and reports for users, applications, desktop, gateways and licenses on the HDX Insight node, by clicking on the respective data-point on the Dashboard. When you access the reports from one of these data points, you get a consolidated report for that data point. For example, click Applications to display the performance chart for all applications (across all NetScaler appliances) monitored by NetScaler Insight Center.
Even when the Appflow is enabled on a NetScaler ADC, I do not see the reports on the Dashboard. What are the possible reasons?

Even if Appflow is enabled on the virtual servers, the services bound to the virtual servers might have AppFlow logging set to disabled. In that case, you might not see the reports in the dashboard. On the NetScaler appliance, enable AppFlow logging at the service level to view the reports. For more information, see Troubleshooting Tips.

How is NetScaler Insight Center different from the Reporting tool on the NetScaler appliance?
The following table explains the basic differences between the Reporting tool and NetScaler Insight Center:
NetScaler Reporting tool NetScaler Insight Center
Web based interface accessed from the NetScaler appliance A virtual machine hosted on a vitalization server like XenServer or VMware ESX server. Multiple NetScaler appliances can be added to the NetScaler Insight Center for monitoring.
Displays performance statistics of the NetScaler appliance on which it runs. Displays L3-L7 performance statistics of all connected NetScaler instances.
Statistics are collected by the nscollect utility. Statistics are collected from the AppFlow records generated by the NetScaler appliances. NetScaler Insight Center adds itself as an AppFlow collector on the NS appliance.
Can I generate a diagnostics bundle from NetScaler Insight Center?

Yes. You can generate a diagnostics bundle and then contact Technical Support to debug an issue.

To generate the diagnostics bundle, on the Configuration tab, navigate to Diagnostics > Technical Support.

You can choose to collect the detailed debug information for the active sessions, and also collect database related detailed statistics.

For more information, see Contacting Technical Support.

How do I generate the diagnostics bundle by using the command line interface?

You can follow the below procedure if access to the GUI fails, or you are unable to generate the diagnostics bundle by using the GUI.

  1. SSH to NetScaler Insight Center.
  2. Log on by using the following credentials:

    Username: nsrecover
    Password: <password of nsroot user>

  3. Run the following command to generate the technical support file:

    /mps/scripts/techsupport.pl

    After the command is executed, the location of the techical support file is displayed.
    For example, var/mps/tech_support/InsightCenter__14Dec2015_05_55_28.tar.gz.
If there are multiple XenApp 6.5 and XenDesktop 7.0 farms, can I uniquely identify AppFlow data for each farm and display the unique data through Desktop Director?

HDX Insight integrated with Desktop Director in a XenDesktop 7.0 farm is limited to one HDX Insight collector per Desktop Director instance. You must have as many Desktop Director instances as you have farms, and configure each Desktop Director to monitor a different farm to obtain the HDX Insight data.

Can NetScaler Insight Center generate custom reports to display specific browser version information for each connection made?

No. This is report is not available in NetScaler Insight Center at this time.

Is there a way to filter reports based on domain name?

No. This is report is not available in NetScaler Insight Center at this time.
