NetScaler Management and Analytics System (MAS) 11.1

Last Modified: Nov 6, 2020 @ 6:51 am


The newer 12.0 version of NetScaler MAS is detailed in a different post.

💡 = Recently Updated


NetScaler MAS is a replacement for NetScaler Insight Center, Command Center, and Control Center. It’s a combination of these three different tools.

NetScaler MAS is a licensed product. It’s free for 30 vServers. Beyond that, licenses can be purchased in 100 vServer packs. Alternatively, you can continue to use Insight Center and/or Command Center.

Requirements for HDX Insight (AppFlow):

  • Your NetScaler appliance must be running Enterprise Edition or Platinum Edition.
  • NetScaler must be 10.1 or newer.
  • HDX Insight works with the following Receivers:
    • Receiver for Windows must be 3.4 or newer.
    • Receiver for Mac must be 11.8 or newer.
    • Receiver for Linux must be 13 or newer.
    • Notice no mobile Receivers. See the Citrix Receiver Feature Matrix for the latest details.
  • For Session Reliability, NetScaler 10.5 build 54 and newer.
  • ICA traffic must flow through a NetScaler appliance:


For ICA round trip time calculations, in a Citrix Policy, enable the following settings:

  • ICA > End User Monitoring > ICA Round Trip Calculation
  • ICA > End User Monitoring > ICA Round Trip Calculation Interval
  • ICA > End User Monitoring > ICA Round Trip Calculation for Idle Connections

Citrix CTX204274 How ICA RTT is calculated on NetScaler Insight: ICA RTT constitutes the actual application delay. ICA_RTT = 1 + 2 + 3 + 4 +5 +6:

  1. Client OS introduced delay
  2. Client to NS introduced network delay (Wan Latency)
  3. NS introduced delay in processing client to NS traffic (Client Side Device Latency)
  4. NS introduced delay in processing NS to Server (XA/XD) traffic (Server Side Device Latency)
  5. NS to Server network delay (DC Latency)
  6. Server (XA/XD) OS introduced delay (Host Delay)


The version/build of NetScaler MAS must be the same or newer than the version/build of the NetScaler appliances.

Import Appliance

You can use either the vSphere Client, or the vSphere Web Client, to import the appliance. In vSphere Client, open the File menu, and click Deploy OVF Template. vSphere Web Client instructions are shown below.

You might see this operating system error when not using the vSphere Web Client. Click Yes to proceed. It seems to work.

  1. Download NetScaler MAS for ESX, and then extract the .zip file.
  2. In vSphere Web Client, right-click a cluster, and click Deploy OVF Template.
  3. In the Select source page, select Local file, and browse to the NetScaler MAS .ovf files. Click Next.
  4. In the Review details page, click Next.
  5. In the Select name and folder page, enter a name for the virtual machine, and select an inventory folder. Then click Next.
  6. In the Select a resource page, select a cluster or resource pool, and click Next.
  7. In the Select storage page, select a datastore. If a single appliance, or if a database appliance, due to high IOPS, SSD or Flash is recommended.
  8. Change the virtual disk format to Thin Provision. Click Next.
  9. In the Setup networks page, choose a valid port group, and click Finish.
  10. In the Ready to Complete page, check the box next to Power on after deployment, and click Finish.
  11. If you try to power on the VM, and you see a message about freeBSD not being supported, then you might have to upgrade the VM Hardware Compatibility Level. VM hardware version 4 seems to be too old.  💡

IP Configuration and High Availability

  1. Open the console of the virtual machine, and configure an IP address.
  2. Enter 7 when done.
  3. When prompted for Deployment Type, enter 1 for NetScaler MAS Server. The first appliance must always be NetScaler MAS Server. Notice the new option for Remote Backup Node.  💡
  4. If you want to deploy two NMAS appliances and HA pair them, enter no for Standalone and yes for First Server Node.
  5. Note: HA is only for database redundancy. All other traffic (SNMP, AppFlow) only goes to one node.
  6. Enter Yes to reboot.
  7. Deploy another appliance.
  8. This time, when asked if First Server Node, enter no. You will then be asked for the IP address of the first node. Enter the nsroot password.
  9. From CTX220000 How to reboot or shutdown Netscaler MAS using CLI: when using the MAS CLI, do not use the reboot command since it will cause data corruption. Instead, run shutdown -r now.
  10. If you need to add a static route to NetScaler MAS, then see CTX223282 How to Add a Static Route on NetScaler MAS.  💡
  11. Once you’ve built all of the nodes, point your browser to the primary NetScaler MAS IP address and login as nsroot/nsroot.
  12. If you see CUXIP, either Skip or Enable the Customer User Experience Improvement Program.
  13. Click Get Started
  14. Select Two servers deployed in High Availability Mode, and click Next.
  15. It should show both nodes. Click Deploy on the top right.
  16. Click Yes to reboot the appliances.
  17. If you login to one of the appliances, at System > Deployment, you’ll see the performance of each node. Notice the Break HA icon on the top right.

  18. You can manage the pair by logging in to either node.
  19. Or you can load balance the pair. Load Balancing is only useful for administration. All other communications (e.g.  SNMP, AppFlow) go directly to one of the nodes. See High Availability Deployment at Citrix Docs for load balancing instructions.

Add Instances

NetScaler MAS must discover NetScaler instances before they can be managed. Citrix Docs How NetScaler MAS Communicates with Managed Instances.

  1. Login to one of the NetScaler MAS appliances.
  2. If you see the Get Started page, click Get Started.
  3. In the Select Deployment Type page, click Next.
  4. On the Add New Instances page, click + New near the top right.

  5. Enter the NSIP address of a NetScaler appliance.
  6. Click the pencil next to ns_nsroot_profile.
  7. Enter the password for the nsroot account.
  8. Enter an SNMP community string that NetScaler MAS will configure on the appliance.
  9. The NetScaler Profile defaults to using https for instance communication. Click OK.
  10. Then click OK to add the instance.
  11. A progress window will appear.
  12. You can add more instances, or just click Finish.
  13. To add more instances later, go to Infrastructure > Dashboard, and on the top right, click All Instances.
  14. Then click New.


Virtual Server License Packs

Without licenses, NetScaler MAS only shows 30 Virtual Servers. You can install additional licenses in 100 Virtual Server packs.

  1. Go to Infrastructure > Licenses > Settings.
  2. On the right, notice the Host ID. Allocate your NetScaler MAS licenses to this Host ID. Then use the Browse button to upload the allocated license file.
  3. You can use the Notification Settings section to email you when licenses are almost fully consumed or about to expire.


Allocate licenses to Virtual Servers 

If you have fewer Virtual Servers than the number of installed licenses, then licenses are automatically assigned to all Virtual Servers. You can manually unassign a license and reassign it to a different Virtual Server.

  1. Go to Infrastructure > Licenses > System Licenses.
  2. On the top right, click Modify licensed Virtual Servers.
  3. In the top row, select the type of Virtual Server you want to unlicense or license.
  4. Select one or more Virtual Servers, and click the Mark Unlicensed button.
  5. Click Yes when asked to mark unlicensed.
  6. To allocate a license to a Virtual Server, click the Add Virtual Servers button.
  7. Select the Virtual Server(s) you want to allocate and click Select.
  8. Click Finish now when done.

Enable AppFlow / Insight

  1. Go to Infrastructure > Instances > Instance type (e.g. NetScaler VPX).
  2. Click the ellipsis next to an instance, and then click Enable/Disable Insight.
  3. At the top of the page are boxes you can check.
  4. With Load Balancing selected in the View list, click the ellipsis next to your StoreFront load balancer, and click Enable AppFlow.
  5. Type in true.
  6. Select Web Insight. If App Firewall is enabled on the vServer then also select Security Insight.
  7. HTML Injection injects JavaScript in HTTP responses to measure page load times.
  8. Click OK.
  9. Use the View drop-down to select VPN.
  10. Click the ellipsis next a NetScaler Gateway Virtual Server, and click Enable AppFlow.
  11. In the Select Expression drop-down, select true.
  12. For Export Option, select ICA and HTTP, and click OK. The HTTP option is for Gateway Insight.
  13. The TCP option is for the second appliance in double-hop ICA. If you need double-hop then you’ll also need to run set appflow param -connectionChaining ENABLED on both appliances. See Enabling Data Collection for NetScaler Gateway Appliances Deployed in Double-Hop Mode at for more information.
  14. By default, with AppFlow enabled, if a NetScaler High Availability pair fails over, all Citrix connections will drop, and users must reconnect manually. NetScaler 11.1 build 49 adds a new feature to replicate Session Reliability state between both HA nodes.
    1. From Session Reliability on NetScaler High Availability Pair at Citrix Docs: Enabling this feature will result in increased bandwidth consumption, which is due to ICA compression being turned off by the feature, and the extra traffic between the primary and secondary nodes to keep them in sync.
    2. If you still want this feature, on NetScaler 11.1 build 49 and newer, go to System > Settings.
    3. On the right, click Change ICA Parameters.
    4. Check the box next to Session Reliability on HA Failover, and click OK.
  15. AppFlow (e.g. HDX Insight) information can be viewed in NetScaler MAS on the Analytics tab.

  1. Hi Carl,

    Thank you for the wonderful detailed document. Please let me know the detailed procedure to generate a CSR for MAS and also let me know the procedure to install a third node as DR. Have configured 2 nodes as HA currently

    Thanks in advance
    Venkatesh K

  2. Carl, for the management certificate is there a way to raise CSR on NMAS and point it to the CA to obtain certificate. Or we only need to bind a wildcard certificate as shown in your screen shots.

    1. I don’t MAS has the ability to create CSRs. But you can create a CSR and certificate on any other machine and then upload it to MAS. It doesn’t have to be a wildcard.

  3. Hi Carl
    We do Citrix cloud where the backend site controllers are managed by Citrix, my question is NMAS Director integration supported in Citrix Cloud.

    1. Hi Carl, is there a way to do the netscaler/director integration without using nsroot and using a domain account that has “lesser/read only” types of permissions? For security purposes…..

  4. Hi Carl,

    How can i configure the NetScaler MAS AppFlow for virtual servers in admin partitions. i am confused on how to do that, because when i try to enable the appflow for my netscaler instance the virtual servers i see are the ones configured in the default partition only, none of the admin partitions appears.

    thanks in advance.

    1. Hi Carl

      I have the same issue as Ismael. My client have 4 admin partition, but form the MAS we are only able to enable the appflow of the default partition. Do is posible to the MASS or the MASS only enable appflow to the default partition ?

    1. Yes. Alerting is free. Backups are free. Configuration Jobs are free.

      You can enable AppFlow for 30 vServers for free.

  5. Hello Carl,

    Thanks a lot for the post.

    Please, hope you could help me with a matter before it could drive me crazy.

    I just deployed a NetScaler ADC to send AppFlow data to a NetScaler MAS. I followed the procedure you posted in order to get Web Insight data. But, I am not able to see any data displayed in Analytics. I perfomed tcpdump in both devices and I can clearly see packets on UDP 4739 going from the ADC to the MAS as follows:

    12:20:42.844119 IP > UDP, length 1470
    12:21:27.196984 IP > UDP, length 220

    The version of the NetScaler ADC is NS11.1
    The version of the NetScaler MAS is 11.1

    The policy and the action I configured are:

    add appflow collector af_collector_192.168.0.160 -IPAddress
    set appflow param -templateRefresh 3600 -httpUrl ENABLED -httpCookie ENABLED -httpReferer ENABLED -httpMethod ENABLED -httpHost ENABLED -httpUserAgent ENABLED -httpContentType ENABLED -httpXForwardedFor ENABLED
    add appflow action af_action_vserver_web_http_80_192.168.0.160 -collectors af_collector_192.168.0.160 -clientSideMeasurements ENABLED -securityInsight ENABLED
    add appflow policy af_policy_vserver_web_http_80_192.168.0.160 True af_action_vserver_web_http_80_192.168.0.160

    Do I need any other policy besides the one posted before?

    Hope you could support me with this issue.



    1. Check /var/mps/log/mps_afdecoder.log for errors.

      I would consider MAS 12.

      Otherwise you might have to call Support.

  6. How to disconnect two VPX’s which are in HA pair in NMAS ? Is there any fuction to do it ? I would like to do it before I will upgrade both appliance to newest version of software.

    1. MAS can send CLI commands to appliances.

      To split a pair, you’d want to clear the config on the secondary. Then remove the HA node from the primary. If you don’t clear the config first, then both will become active.

  7. Hi Carl,

    For XenApp/XenDesktop deployment, can I only deploy a single NetScaler MAS next to the NetScaler VPX?
    Will the XenDesktop ICA traffic disrupt when NetScaler MAS is out of service?


    1. You can configure AppFlow to send to multiple collectors.

      AppFlow is UDP, so it doesn’t know if the packet was received by MAS or not. MAS being down should not affect ICA.

  8. Great article Carl! Here is what I dislike about the MAS. When I go the top left hand corner, hamburger menu, into “Networks”…”licenses”…”system licenses” I see I am “allowed” 30 virtual server licenses. But I only want the MAS to manage 11 of those. when i go and “modify licensed virtual servers” and remove the ones I do not want the MAS to manage, logout and log back in, the MAS auto populates the 30 back, and it is random…. This is so frustrating and useless, I choose not to use the MAS because of this. Does this make sense to anyone?? I have complained about this for some time and have been ignored by support. I get the typical, ” it will be fixed in the next release bull crap. Started out with the beginnings of MAS, upgraded through 5 or 6 different versions, presently at 12.0 41.22

  9. Hi Carl, Thanks for info. i am using MAS. There is no log on the MAS when the devices are failover. Have you encountered such a problem, what do you suggest?

  10. Hi Carl, do you have the list of ports that need to allowed for MAS to show Insight data from NetScalers in DMZ? Like the one you had for command center.

  11. Perfect ! Thanksgiving forma these kind of post. The only thing not mentioned Is a how to creare a CSR, which in Citrix docs Is not updated . Now you have to do right click on a Blank space where a cert should be . Thanks

  12. Hi Carl,

    Do you know if MAS is capable of tracking usernames of users that are currently in session (connected) through a AAA server and displaying this in analytics?



    1. Citrix says that binding the AppFlow policy globally enables AAA logins to appear in Gateway Insight.

  13. Awesome article Carl, your website is very helpful for Citrix Admins. I have run into a little snag with NetScaler MAS . Everything is configured and working. I have also integrated it Citrix Director. I have 2 Director servers LB by my Netscaler VPX. So I just If i go to my LB URL and click on the Network tab I get a “Session Expired” error. If i go to the URL of 1 of the director server directly, everything works fine. Any insight on this?

  14. Carl,
    Is the ICA Session Timeout what it sounds like? Does it allow you to set Session limits from MAS for connections across the gateway?

  15. Hey Carl. Any tips on Nmas receiving APPFW violations? For eg, ip repuation triggers but I see NA against the repuation field in NMAS

  16. Carl have you heard any news on when MAS will support scale-out deployments? Having a single-subnet HA pair isn’t really ideal for large multi-datacenter deployments.

      1. As of this:, multiple times throughout the document this comment is made: “Currently, you cannot deploy connector nodes, database nodes, and/or NetScaler MAS agents because NetScaler MAS does not support Scale-Out deployment.”

        I skimmed through the Release Notes and did not see any comments about the return of that functionality. I am basing my information on this article and admittedly have not tried yet -so it is possible it has quietly returned?

  17. Great info. & website.

    I am new to Citrix, just started. I am setting up MAS- single server deployment in VMWare.
    My question is how to assign IP address to 2nd Nic and add static routes. I tried configuring in ” rc.conf ” file but every time i reboot machine the file goes back to default?

    Any idea …?


  18. HI Carl,

    first – great article! like so often.

    at the config Point

    “Enter an SNMP community string that NetScaler MAS will configure on the appliance.”

    -> should we use a new community string at this point or an existing one on a NS Appliance where is there configured?

    ive some trouble by adding the first NS VPX Appliance. i received always the issue:

    Trying to connect to
    Error: License cannot be retrieved. Either the NetScaler is unresponsive or the login credentials are incorrect.

    iam using the NS MAS Vers. 1 / Built


    1. NMAS uses several ports to connect to the NSIP of the NetScaler appliance. Run “tail -f /var/log/ns.log” on the NetScaler while performing NetScaler MAS discovery and see if any commands make it to the appliance. It might help you find the issue.

      1. found the issue, ill try to connected NS VPX V11 Built 55.20 without any success. ive upgrade to NS VPX V11 Built 64.34 and adding via NS MAS works fine

  19. Hi Carl,

    Thank you so much for your site and all the work you do, it is an amazing help!!!

    Do you know the port requirements between NetScaler instances and MAS? I can not find it listed in the Citrix edocs.


    1. I suspect a combination of Command Center and Insight Center. TCP 22. TCP 443. SNMP ports. Then there’s AppFlow, SNMP, and Syslog from appliance back to MAS.

  20. Hi, Carl:

    Thanks your great info, Netscaler MAS can integrate with Director now ?
    I run the command in Director but it show “This content can not be displayed in a frame” in Director…..
    Do you know this issue ?

        1. Also, while you’re there.. have you seen the image on the eDocs about HDX Insight through MAS, where all the various metrics (WAN latency, RTT etc) are shown on the same graph? I don’t seem to be able to do that from the Users info, they are all split into separate graphs?

    Really great info… have you found anything that Insight can do that MAS can’t yet?

      Other than licensing, I haven’t found any limitations yet.
