Notes:
Fixed Issues
The issues that are addressed in Build 50.10.
Analytics
  • NetScaler MAS Analytics displays the NetScaler HA failover count per ICA session whenever HA failover happens, and a reconnect occurs using session reliability.
    [# 644975]
  • The value of the X-Forwarded-For HTTP header field is not displayed as client IP address in Security Insight violation logs.
    [# 645284, 636390]
  • If URL reporting is enabled, analytics subsystem might fail, and reports might not be displayed.
    [# 649947]
  • When you upgrade the NetScaler appliance from 11.0 release to a newer release (11.1 or higher), Security Insight is disabled.
    [# 653626]
  • For a NetScaler appliance in multicore setup, reports from all cores were not getting generated except "0" core.
    [# 656225]
  • If you add CloudBridge appliances in NetScaler MAS, Web Insight reports might not be displayed.
    [# 659008]
  • Geo location does not resolve from Maxmind GeoCity.dat database file.
    [# 656017]
  • When you use LDAP for external authentication, you might receive a "Error: Resource does not exist" error message when you click the Configuration tab.
    [# 658344]
AppFlow
  • If the NetScaler appliance sends AppFlow data with application firewall records to NetScaler MAS, the appliance might fail. This might occur if the built-in NOPOLICY policy, which does not have any specified action, is configured as a global policy.
    [# 656771]
  • Automatic client reconnection (ACR) for Linux VDA clients fails if the NetScaler appliance is in the path and ICA AppFlow is enabled for the appliance.
    [# 648254]
Infrastructure
  • If the frequency of a job is scheduled as "once" for a specific time and date, the job is executed immediately instead of getting executed at the scheduled time.
    [# 654763]
System
  • When multiple NetScaler MAS servers access a NetScaler instance at the same time to back up the instance, backup files might get overwritten. To prevent this, a random string is now appended to the backup files.
    [# 658479]
  • Earlier, when trying to remove or edit a threshold, the following error message appeared even for an nsroot user: "Not authorized to perform this operation." Now, you can remove or edit previously created thresholds on NetScaler MAS.
    [# 654615]
Known Issues
The issues that exist in Build 50.10.
Analytics
  • For content switching virtual servers, the NetScaler MAS GUI does not display the options to enable AppFlow for Web Insight and Security Insight.
    [# 665336]
  • The time interval for which data is displayed on the dashboard might not match the selected time interval. If no data is available for part of the selected time interval, NetScaler MAS shows data from the date on which it started receiving the AppFlow data.
    [# 601474]
  • After you update the country/region/city information for the IP Block, Geo report displays the existing information.
    [# 617352]
  • In Security Insight, Safety Index filters display incorrect output.
    [# 640160]
  • In Security Insight, on the Application Summary page, IP reputation is not displayed in the Violation Category drop-down list.
    [# 643629]
  • In a NetScaler MAS high availability setup, the Analytics configuration does not work.
    [# 642270, 644542]
  • In Security insight, Search option drop-down list for Application Summary does not include all the filters.
    [# 630031]
  • For NetScaler SD-WAN, while using the "SetTrafficShapingPolicy" built-in template to execute Configuration jobs, you are required to specify values for all parameters, even if they are not mandatory.
    [# 613965, 613962]
Infrastructure
  • Users within a tenant group can view all jobs, including jobs on NetScaler instances to which they are not assigned.
    [# 647539]
  • Traps forwarded from the NetScaler MAS server when a "Send Trap" rule is configured on events, always have the Community set to "public" (the default).
    [# 647610]
Licensing
  • By default, NetScaler MAS randomly selects the virtual servers to monitor on the basis of your license. For example, if you have a license for 130 virtual servers, by default, NetScaler MAS randomly selects 130 virtual servers to monitor. If you want to monitor a smaller number of virtual servers, you can deselect the virtual servers you do not want to monitor. These virtual servers become unlicensed, freeing up that number of licenses. However, the next time that NetScaler MAS polls, the unlicensed virtual servers are randomly added for monitoring, which uses up the available licenses.
    [# 658385]
Orchestration
  • If a network gets disconnected while you are autoprovisioning NetScaler instances on NOVA, you should not perform other operations on the NetScaler instances. Doing so could result in the instance becoming unstable. In that case, you might have to ask Citrix technical support to reconfigure the instance.
    [# 590687]
  • In orchestration, when a NetScaler instance is unassigned from a service package, the interfaces configured for the instance are lost.
    Workaround: The interfaces should be reconfigured if the same NetScaler instance is assigned to another service package.
    [# 620635]
  • In orchestration, if you perform "Cleanup" operation for requests on which rollback failed, the following error message is displayed: "Rollback is not allowed for successfully completed requests".
    Workaround: You can refresh the page to view if the failed rollback has succeeded.
    [# 601294]
  • For NSX Integration, a VLAN is allotted for every VXLAN during service insertion. The VLANs do not get de-allotted when service insertion is disabled/deleted. Because of this VLANs might get exhausted.
    [# 648726]
  • In OpenStack integration, the installation files and scripts in the NetScaler driver bundle, and the configurations in the neutron.conf file, display NetScaler Control Center options instead of the required NetScaler MAS options.
    Workaround: When prompted for the IP address of the machine running NetScaler Control Center, enter the IP address of the machine running NetScaler MAS. For example, while installing the driver install.sh, specify the MAS IP address for the "--ip" option even though prompted for controlcenter_ip.
    [# 653696]
StyleBooks
  • When you create a configuration from a shipped StyleBook, a “certkey” is added before it is bound to the virtual server on the target instance. Therefore, if you try to bind an existing “certkey” by providing the same “certificate file” and “certificate key file”, an error occurs because the “certkey” is already present on the target instance.
    [# 665100]
  • In the "Sample Application StyleBook using CS, LB and SSL features" (sample-cs-app) StyleBook, the name of the application is hard coded. Therefore, using this StyleBook you can create only one application configuration on a target device. If you try to create a second configuration from this StyleBook, an error message is displayed mentioning that the resource already exists.
    [# 665099]
System
  • After migrating from NetScaler Insight Center to NetScaler MAS, you cannot log on to NetScaler MAS by using the administrator credentials.
    Workaround: To enable logon to NetScaler MAS, you must manually start the masd daemon.
    [# 665410]
  • NetScaler MAS restarts as soon as you apply the required Cipher group and click "OK" even before you click "Done". The NetScaler MAS should restart after you click "Done". Also, NetScaler MAS should display a confirmation pop-up message before the system restarts.
    [# 660805]
  • In a NetScaler MAS high availability setup, when you back up and restore the system, the instance backup settings (System > System Administration > Instance Backup Settings) do not get backed up and restored to the values that were set prior to taking the backup.
    [# 661049]
  • In NetScaler MAS, when you apply the required Cipher group to configure the SSL settings, the system selects the last created cipher group by default even when you apply any other group created previously. The system should select the group that was applied.
    [# 660799]
What's New in Previous NetScaler MAS 11.1 Releases
The enhancements and changes that were available in NetScaler MAS 11.1 releases prior to Build 50.10. The build number provided below the issue description indicates the build in which this enhancement or change was provided.
Analytics
  • X-Forwarded-For HTTP Header Support for Security Insight Reports
    The X-Forwarded-For HTTP header field is a common method for identifying the originating IP address of a client connecting to a web server through an HTTP proxy or load balancer. NetScaler MAS uses X-Forwarded-For HTTP header to obtain the following details:
    - The address of the client which connected to the proxy.
    - The content of the host header the client sent to the proxy.
    Currently X-Forwarded-For support is available only for Web Insight and Security Insight.
    Note: You can only enable or disable the X-Forwarded-For feature using the NetScaler appliance's CLI.
    To enable this feature, at the command prompt, type: "set appflow param httpXForwardedFor ENABLED".
    [From Build 49.16] [# 636390]
  • Comparing Graphs in NetScaler MAS Analytics
    You can now combine any two graphs in NetScaler MAS Analytics (Insight) to view and compare the selected parameters.
    [From Build 49.16] [# 617967, 593755]
  • Support to Migrate NetScaler Insight Center to NetScaler MAS
    You can now migrate your NetScaler Insight Center deployment to NetScaler MAS without losing the existing configuration, settings, or data in NetScaler Insight Center. With NetScaler MAS you can not only view the various analytics data generated by the NetScaler instances associated to an application, but you can also manage, monitor, and troubleshoot the entire global application delivery infrastructure from a single, unified console. Note that you can only migrate a standalone NetScaler Insight Center deployment to a standalone NetScaler MAS deployment. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/migrating-netscaler-insight-center-to-mas.html
    [From Build 49.16] [# 632967, 649903]
  • Support to Integrate NetScaler MAS with Citrix Director
    NetScaler MAS is now integrated with Citrix Director. This enables Director to display HDX Insight reports from NetScaler MAS in the Network and the User details page and provides has user, applications, desktops, instances and license specific information. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/integrating-netscaler-mas-with-drector.html.
    [From Build 49.16] [# 647135]
AppFlow
  • If a NetScaler high-availability failover occurs when ICA AppFlow is enabled, the session reliability feature will now restore the session. This capability is currently disabled by default and configurable via CLI. The CLI command to enable/disable the feature is
    set ica parameter EnableSRonHAFailover YES/NO
    [From Build 49.16] [# 456218, 438710, 547601, 620411]
Application Management
  • Using Regular Expressions to Configure Load Balancing Virtual Servers in NetScaler MAS
    When defining an application from Applications > Dashboard > Applications > New Application, you can now use regular expressions to select multiple virtual servers. For example, the owa|lync expression selects all virtual servers that contain "owa" or "lync" in their names.
    [From Build 49.16] [# 657447]
  • Editing the name of the application
    When you create an application (Applications > Dashboard > Applications), earlier there was no option to edit the name of the application. With this fix, you can edit the name of the application at any later time.
    [From Build 49.16] [# 644896]
  • Configuring Load Balancing Virtual Servers From the Application Dashboard
    You can configure load balancing virtual servers and bind or unbind services and service groups from the Application Dashboard screen of the NetScaler MAS. For more information, see http://docs.citrix.com/en-us/netscaler-mas/11-1/application-management-how-to-articles/load-balancing-support-through-application-dashboard.html.
    [From Build 49.16] [# 653169]
Infrastructure
  • Reusing Completed Configuration Jobs on NetScaler MAS
    You can now modify the commands, parameters, configuration settings, and instances in a completed or a scheduled job and execute the job again. This is useful when you want to execute the same set of commands on a different instance or when the job encounters an error and stops further execution. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/configuration-jobs-replicate-configuration.html.
    [From Build 49.16] [# 637401]
  • Wildcard Character Support for Failure Objects
    You can now use the wildcard character search for failure objects to apply to a rule. You can use * as a wildcard character in the Add field above the Failure Objects parameter in the Create Rule page, to search for similar failure objects that can be applied to the rule. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/event-management-how-to-articles/how-to-set-multiple-event-rules-notifications-mas.html.
    [From Build 49.16] [# 653144]
  • Unrecognized Failovers in NetScaler MAS
    Earlier when failover occurred on NetScaler instances in a high availability mode, NetScaler MAS was unable to detect the state change until the next polling by the system. Now, when failover occurs on NetScaler instances in a high availability mode, NetScaler MAS updates the primary or secondary node's state based on SNMP traps received by NetScaler MAS when the instance state changes.
    [From Build 49.16] [# 657297]
  • Support to View Host Names with IP Addresses of NetScaler Instances
    You can now view the host name along with the IP address of your NetScaler instance across all tables and graphs in NetScaler MAS. Previously, only the IP address was displayed, making it difficult to keep track of thousands of instances. By assigning host names, you can now identify instances more easily.
    [From Build 49.16] [# 649667]
  • View Instance User Information in Execution Logs
    Execution logs are generated when you create and execute a job that contains the NetScaler user (Instance User) whose credentials were used to perform the action. Previously, only the MAS user’s name was displayed in the execution log. In some cases, both the MAS user and the NetScaler user had the same system credentials, nsroot/ nsroot. In this situation, should your NetScaler profile be changed, you can rediscover the instance with its new user credentials and execute the job again. You can then see the new instance user credentials in the execution summary.
    To view execution logs with system and instance name, navigate to Infrastructure > Configuration Jobs. Select a job and click Details. Click Execution Summary to see the status of the instance on that executed the job and the instance user's name. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/configuration-management-how-to-articles/how-to-create-configuration-job.html
    [From Build 49.16] [# 653167]
  • Support to Send Email Notifications when Jobs are Executed
    Email notifications can now be sent every time a job is executed or scheduled. The notifications provide information such as the success or failure of the job, and include relevant details. If you have created a job in NetScaler MAS to perform specific configuration changes on a NetScaler appliance, and you want to know if the scheduled task has succeeded or failed, you previously had to log back on to NetScaler MAS and check the execution logs. You can now direct NetScaler MAS to send an email reporting on the success or failure of the task. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/configuration-management-how-to-articles/how-to-create-configuration-job.html
    [From Build 49.16] [# 652828]
  • Email Notification Support to Send Configuration Audit Notifications for Saved v/s Running Config Differences
    You can now configure NetScaler MAS to send email notifications every time the saved configuration is different from the running configuration on managed NetScaler instances. A configuration might get changed when you manually poll your instances, or if you have scheduled a configuration to be run at a particular polling interval. For more information, see https://docs.citrix.com/en-us/netscaler-mas/11-1/nmas-audit-configuration-instance.html
    [From Build 49.16] [# 653168]
Licensing
  • Expiry Check Support for Virtual Server Licenses
    You can now view the status and set alerts for the virtual server licenses expiry in NetScaler MAS. This helps you plan your license upgrades on time. You can set the expiry notifications to be received through email or through SMS. To view the status of the licenses, navigate to Infrastructure > Licenses > System Licenses. Then, in the License Expiry Information section, you can find the details of the licenses that are going to expire. For more information, see http://docs.citrix.com/en-us/netscaler-mas/11-1/netscaler-mas-licensing.html
    [From Build 49.16] [# 649426, 660051]
  • Management and Monitoring Support for Virtual Servers through NetScaler MAS
    You can now select the virtual servers to manage and monitor through MAS. To manage licensed virtual servers, navigate to Infrastructure > Licenses > System Licenses, and select Modify Licensed Virtual Servers to license/un-license the virtual servers. For more information, see http://docs.citrix.com/en-us/netscaler-mas/11-1/netscaler-mas-licensing.html
    [From Build 49.16] [# 649425, 649591]
  • Port Configuration Support for License Server Client
    If your network firewall does not allow the using of ports above 10000 for communication between license server (port 27000) and NetScaler instances, you can use vendor daemon port (7279) for communication. For more information, see http://docs.citrix.com/en-us/netscaler-mas/11-1/netscaler-mas-licensing.html
    [From Build 49.16] [# 649424]
StyleBooks
  • StyleBooks for NITRO Entities Available on NetScaler MAS
    Built-in StyleBooks corresponding to all NITRO entities for releases 10.5, 11.0, and 11.1 are now available on NetScaler MAS. You cannot access these StyleBooks from the NetScaler MAS GUI. To access these built-in StyleBooks, you have to use StyleBooks API requests.
    For example, to get the definition of a built-in StyleBook for lbvserver resource of NetScaler NITRO API, you have to use the following GET request:
    [GET] http://<mas_ip>/stylebook/nitro/v1/config/stylebooks/netscaler.nitro.config/<netscaler_release>/lbvserver
    To create a load balancing virtual server on the target instance with the specified attribute values, you have to use the following POST request:
    [POST] http://<mas_ip>/stylebook/nitro/v1/config/stylebooks/netscaler.nitro.config/<netscaler_release>/lbvserver
    payload:
    {
    "configpack": {
    "parameters": {
    "name": "test-lb",
    "servicetype": "HTTP",
    "ipv46": "101.102.11.10",
    "port": 80
    },
    "target_devices": {
    "<device IP>": {
    "id": "<device_id>"
    }
    }
    }
    }
    For more information on how to use APIs to create configurations from StyleBooks, see: http://docs.citrix.com/en-us/netscaler-mas/11-1/stylebooks/how-to-use-api-to-create-configuration-from-stylebooks.html
    [From Build 49.16] [# 644498]
  • Support for File Uploads From StyleBooks by Using NetScaler MAS GUI
    To upload certificate file and certificate key file, two new types of parameters are now available, "certfile" and "keyfile". For these two parameter types, you can now upload the files directly from your local system when you are creating a StyleBook configuration using the NetScaler MAS GUI. The uploaded certificate file is stored in the directory /var/mps/tenants/<tenant_path>/ns_ssl_certs and the certificate key file is stored in /var/mps/tenants/<tenant_path>/ns_ssl_keys in NetScaler MAS. These uploaded certificates become part of the certificates managed by NetScaler MAS.
    For uploading any other type of file, you can use the parameter type "file". In this case, you have to first manually upload the file to /var/mps/tenants/<tenant_path>/ on NetScaler MAS, before you can use that file in a StyleBook configuration.
    When creating configurations from StyleBooks, you must provide only the name of the file you want to upload if you are using the API for any of the three parameters types or if the parameter type is "file" (from NetScaler MAS GUI or API). You must not provide the complete path of the files. The files are expected to be already available in the respective folders.
    [From Build 49.16] [# 645248]
  • Configure Alerts and Collect Analytics Data on a Virtual Server Defined by Using a StyleBook
    You can now use the operations construct in StyleBooks to configure NetScaler MAS analytics alarms on any virtual server created through the StyleBook. The attributes in this construct are used to set thresholds to generate alarms and send notifications on the virtual server. For example, you can configure an alert to send notification if the total requests handled by a load balancing virtual server is greater than 25 and for a period defined by the user. For more information, see: http://docs.citrix.com/en-us/netscaler-mas/11-1/stylebooks/how-to-enable-analytics-on-virtual-server-defined-in-stylebooks.html
    [From Build 49.16] [# 627838]
System
  • Compressing Core Files to Save Disk Space
    The NetScaler MAS server now compresses the backup files that are generated during the "backup and restore" process. This ensures that the backup files now occupy minimum storage within the server.
    [From Build 49.16] [# 654672]

    [From Build 49.16] [# 654374]
  • After selecting one of the cloud platforms and submitting the form with the required settings under Orchestration, you are redirected to the Cloud Platform Selection page instead of the Deployment Settings page. With this fix, when you now select one of the cloud platforms and submit the form, you are redirected to the Deployment Settings page.
    [From Build 49.16] [# 648355, 648561]
System
  • In NetScaler MAS, when you configure instance backup settings (System > Instance Backup Settings), the backup files are generated randomly and not at the set time interval. Also, the older backup files are not being deleted in the order that they were created.
    [From Build 49.16] [# 661153]
  • Earlier, when trying to remove or edit a threshold, the following error message appeared even for an nsroot user: "Not authorized to perform this operation." Now, you can remove or edit previously created thresholds on NetScaler MAS.
