    [# 690858, 681022]

Networks

  • Pre-Upgrade Validation of NetScaler Instances, using NetScaler MAS
    You must now perform pre-upgrade validation checks before using NetScaler MAS to upgrade the Netscaler instances. Pre-upgrade validation includes the following checks:
    • Check for any existing customizations of NetScaler instances. Removing the customizations before performing the other pre-upgrade checks is recommended.
    • Check the disk usage of NetScaler instances. If the disk usage is more than 80%, clean up the disk space.
    • Check for disk hardware issues on NetScaler instances.
    If the instances do not pass the pre-validation checks, proceeding with the upgrade process is not recommended.
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/configuration-management/how-to-upgrade-netscaler-instances-using-mas.html.
    [# 677556]
  • Using NetScaler MAS to Remove Image Files used for Upgrading NetScaler MAS and NetScaler Instances
    When you upgrade NetScaler MAS, the NetScaler MAS image files are copied to the corresponding /var/mps/mps_images folder. To prevent image files from occupying storage space after you upgrade NetScaler MAS, you can select an option to have the images deleted automatically. NetScaler MAS then deletes these images from the /var/mps/mps_images after the upgrade is successful. In addition, images copied to a NetScaler instance's /var/nsinstall directory in NetScaler MAS when the instance is upgraded are removed after the upgrade is successful.
    To select this option in NetScaler MAS:
    1. Navigate to System > System Administration, and click Upgrade NetScaler MAS.
    2. On the Upgrade NetScaler MAS page, select the "Clean software image on successful upgrade" option.
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/upgrade.html.
    [# 684236]
  • Saving variable definition and details while saving a config job
    The values that you specify for the variables when you create config jobs are now retained by NetScaler MAS when you save the job and exit, or when you schedule a job to be run at a later time.
    [# 637830]
  • Support for customized SSH port for NetScaler instances in NetScaler MAS
    You can now customize the SSH port used for communication between the NetScaler MAS and NetScaler instances.
    To set the SSH port for the Device Profiles
    1. Log on to NetScaler MAS using a supported web browser.
    2. Navigate to Networks, and select the device type of the NetScaler Instance you want to discover in NetScaler MAS.
    3. Click Profiles.
    4. In the Admin Profiles page, click Add.
    5. In the SSH Port field, enter the configured custom SSH port number for NetScaler Instances to communicate with NetScaler MAS.
    6. Click Ok.
    [# 689369, 686738]
  • Built in report of all Device > Partition > VIP > Service Group/Service bindings
    You can now export a report of all the load balancing entities configured on the managed NetScaler instances. The report provides a high-level mapping of all NetScaler instances, partitions, virtual servers, services and service groups. You can download the report instantly in csv format, or schedule the reports to be sent as a mail attachment daily, weekly and monthly.
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/network-functions/how-to-generate-reports-for-load-balancing-entities.html
    [# 663174]
  • Syslog suppress filters
    When configured as a syslog server, NetScaler MAS receives all syslog messages sent to it by the configured NetScaler instances. There might be a large number of messages that you might not want to see. For example, you might not be interested in seeing all informational level messages. You can now discard some of the syslog messages that you are not interested in. You can suppress some of the syslog messages coming into NetScaler MAS by setting up some filters. NetScaler MAS drops all messages that matches with the criteria. These dropped messages do not appear on the NetScaler MAS GUI and these messages are also not stored in the customer's NetScaler MAS database.
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/event-management/how-to-suppress-syslog-messages.html
    [# 679274]
  • Support for NetScaler SD-WAN SE in NetScaler MAS.
    You can now add the NetScaler MAS server as an AppFlow collector in the NetScaler SD-WAN SE/EE appliance or using the NetScaler SD-WAN Center. The NetScaler SD-WAN SE/EE appliance sets up a profile and registers itself as a managed device in NetScaler MAS. You can then view TCP for HDX data of these instances in NetScaler MAS.
    [# 657222]

System

  • Ability to add static routes
    You can configure a route in NetScaler MAS to establish a connection between NetScaler MAS and the NetScaler VPX instances deployed in the cloud.
    [# 689126]

    [# 684924]
  • While creating a new configuration job, selecting the "Save as Configuration" does not give any error.
    [# 686385]
  • Networks dashboard in NetScaler MAS might display wrong count of NetScaler instances.
    [# 688491]
  • In NetScaler MAS, the Hamburger icon (menu icon on the right corner) changes to Close icon (X) when clicked to open the Navigation Menu. With this fix, if we open any configuration page for example, Add Instance, Configure Insight and others, the navigation menu panel is hidden, and the "X" icon is disabled.
    [# 687203]
  • In NetScaler MAS, if you try to delete the default certificates of any discovered NetScaler instances, an error message is displayed. Now once you select the default certificates, "Delete" button is disabled.
    [# 687610]
  • An unexpected single space is added in the command after you replace the variable with a user-defined value.
    For example, in the following command, the variable $env$ is replaced with the value of "qa" and an unexpected space is appended by NetScaler MAS, which results in failure of the command.
    Command:
    chmod 555 /var/custom/config-* && /var/custom/config-$env$.sh
    Replaced Command:
    chmod 555 /var/custom/config-* && /var/custom/config-qa .sh
    [# 688154]
  • When you create a group using the NetScaler MAS Group UI wizard, the success message that describes that the group is created is displayed before the wizard is finished.
    [# 684944]
  • When you create a new configuration job, NetScaler MAS verifies the existence of a job with the same name. If there is a job with the same name, NetScaler MAS displays an error saying that a configuration job already exists with the same name for the same tenant when you click "Next" on the "Select Configuration" screen.
    [# 686883]
  • In NetScaler MAS, when you are running a configuration job using a Master Config template created by using C# API, jobs in pending state show Zero percent as progress and it is not possible to abort them.
    This issue was seen in customer environment when category was not set for Master Config templates created by using C# API, as setCategory method is not available in the API. As set category issue is fixed as part of #687591, this issue cannot be reproduced.
    [# 686878]
  • In NetScaler MAS, when you are creating a configuration job, the list of templates is not updated when the type of the configuration source is changed.
    [# 686880]
  • If entity polling by NetScaler MAS discovers a very high number of NetScaler instances, the NetScaler MAS GUI might become unresponsive.
    [# 692617]

Orchestration

  • You can now view load balancer statistics from OpenStack by using a Neutron CLI command: neutron lbaas-loadbalancer-stat. This command fetches cumulative statistics of all listeners corresponding to the OpenStack load balancer from NetScaler MAS and displays them on the OpenStack console. Make sure that you have installed the latest driver, which is part of the current NetScaler MAS build.
    [# 692245]

Settings

  • In NetScaler MAS, while using Nitro SDKs, setters for "Category" property is not available in Configuration Templates resource.

    You can now integrate NetScaler Secure Web Gateway (SWG) log data into the NetScaler Management and Analytic System (MAS). The NetScaler SWG appliance exports its logged user activity and the subsequent records to NetScaler MAS by using logstream. NetScaler MAS then collates and presents information about the activities of users (for example, websites visited and time spent on line). It also reports bandwidth use and detected threats, such as malware and phishing sites. You can use these key metrics to monitor your network and take corrective actions with the NetScaler SWG appliance.
    [From Build 51.24] [# 606272]

Application Analytics and Management

  • Application Health Dashboard
    Note: This feature is currently available in Beta.
    The health score is the product of a scoring system that defines how well an application is performing. It shows whether the application is performing well in terms of responsiveness, is not vulnerable to threats, and has all systems up and running. Health Score is displayed at the application level. Calculation of the score is based on the following three key components, which defines Health Score:
    - APP Performance (APDEX score of the application)
    Derived from the response time variation of the application.
    - App Server Resource
    This value is derived from three more components:
    > Average CPU Usage
    > Memory Usage
    > NIC Card Saturation
    - NetScaler System Resource
    This value is derived from two more components:
    > Percentage of Active Services
    > Surge Queue Requests
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/application-analytics-and-management/application-security-analytics.html.

  • Audit Templates created in Configuration Audit module are now available in Configuration Jobs module
    You can create audit templates in Configuration Audit module in NetScaler MAS to make sure that certain configurations exist on your NetScaler instances and to check the instances regularly for any deviation. NetScaler MAS allows you to save this template in the system so that the audit template is available in Configuration Jobs module also. Now the audit templates can be used to create configuration jobs. This allows the audit templates to be used interchangeably between configuration jobs and configuration audits.
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/configuration-management/how-to-reuse-configuration-audit-templates-in-configuration-jobs.html
    [From Build 51.24] [# 664123]

Orchestration

  • Creating basic load balancing configuration from VMware NSX Manager GUI
    The VMware NSX Manager GUI now supports StyleBooks. With this enhancement, you can create the complete load balancing configuration from this GUI. NetScaler MAS uses built-in stylebooks to deploy the load balancing configuration. Previously, you had to deploy StyleBooks in NetScaler MAS in order to deploy load balancing configurations or applications on NetScaler.
    Do the following to enable configuration of load balancing from the VMware NSX Manager GUI:
    1. Open the /mps/stylebooks/scripts/shipped_stylebooks_list.sh file in NetScaler MAS.
    2. Edit the file.
    3. Add the following two StyleBooks to the end of the StyleBooks list in shipped_stylebooks_list.sh.
    a. nsx-root-params
    b. nsx-lb-mon
    4. Restart NetScaler MAS services by entering the masd restart command.
    [From Build 51.24] [# 687279]

StyleBooks

  • Prompt users for instance credentials when creating configpacks
    A new option has been added to NetScaler MAS that when enabled, requires you to provide your credentials that you use to login to the NetScaler instances during the creation or update of a configpack. If this option is not enabled, NetScaler MAS would always use the user credentials stored in the device profile when connecting to the NetScaler for creating or updating a configpack.
    [From Build 51.24] [# 681706]

System

  • Instance Backup Settings
    You can now configure NetScaler MAS to create automatic backup files of NetScaler instances in the network at a specific time (hour and minute). This is in addition to the backups created at a specified interval. Additional updates to instance backup settings are the following:
    . You now have the option to disable the creation of device backups by NetScaler MAS. #683315
    . Because of the large size of Geo database files, you now have the option to selectively include or exclude them in the backup files. # 683833
    . You can now transfer the NetScaler instance backup files to an external location by specifying the IP address of the external storage device. # 680907
    . NetScaler MAS can now reexecute the task of backing up an instance once every 30 seconds. # 680795
    . NetScaler MAS can now send an SNMP trap or a Syslog notification when it is unable to create a backup file for the selected NetScaler instance. # 683832
    . NetScaler MAS can now create a backup file whenever a NetScaler instance sends a NetScalerConfigSave trap to NetScaler MAS. # 678285
    . You can retain up to 50 backup files of the current state of a NetScaler instance. The default is three backup files. # 672123
    For more information, see http://docs.citrix.com/en-us/netscaler-mas/12/instance-management/how-to-backup-and-restore-using-mas.html
    [From Build 51.24] [# 675654]
  • NetScaler MAS High Availability Active-Passive deployment
    A high availability deployment (HA) of NetScaler MAS servers now deploys two servers in an active-passive HA mode. One NetScaler MAS server is deployed as the active node and the other as the passive node. Both servers have the same configuration. If, for any reason, the active node goes down, the passive node takes over (a process called failover). This deployment type is ideal for disaster recovery.
    If you are upgrading your NetScaler MAS HA setup from a previous build to this build, make a note of the following before you begin upgrading your setup:
    * The NetScaler MAS active-passive HA deployment mode is supported from NetScaler MAS version 12.0 build 51.24.
    * The upgrade process changes the active-active HA setup to an active-passive HA setup.
    * As part of the upgrade process, all configurations are updated such that all NetScaler instances are now managed by the active node. This is applicable to all configurations such as SNMP, Syslog, Analytics, and so on.
    * After you upgrade the NetScaler MAS to active-passive mode, some NetScaler instances will still continue to send traffic to the passive node for approximately 5 minutes. As a result, the incoming traffic will be lost for that duration.
    * If you had configured a load balancing virtual server for unified management access of your NetScaler MAS servers, after you upgrade the NetScaler MAS HA pair to active-passive mode you have to run the following command on the NetScaler appliance to update the load balancing configuration:
    add lb monitor MAS_Monitor TCP-ECV -send "GET /mas_health HTTP/1.1\r\nAccept-Encoding: identity\r\nUser-Agent:NetScaler-Monitor\r\nConnection: close\r\n\r\n"" -recv "{"statuscode":0,"is_passive":0}" -LRTM DISABLED
