KEMP 360 Release Notes

1Installing and Upgrading KEMP 360 Central

First-time installation of KEMP 360 Central is supported on a number of platforms. In addition to reading these Release Notes, please also read and follow the Installation Guide for your platform, available from the KEMP Documentation Library. Expand the KEMP 360 link at the top left of the library contents and then click on the installation guide for your platform.

Upgrading directly to the latest version of KEMP 360 Central is supported from Version 1.9 or a later release only. For details on the upgrade path to the current release, please see the section Upgrade Path to the Latest Release on page 22.

If you are running a release of KEMP 360 Central earlier than Version 1.9, please contact KEMP support to upgrade to Version 1.9 before attempting to upgrade to the latest release:

http://kemptechnologies.com/load-balancing-support/kemp-support

To update KEMP 360 Central to the latest firmware version, click the Settings and Configuration icon (the gear icon) at the bottom-left corner of the UI and then click Firmware Management.

1.1Before You Begin

The following are requirements and recommendations for installing and using KEMP 360 Central:

  • Before attempting to add a LoadMaster to KEMP 360 Central, ensure that the LoadMaster is running Version 7.1.34 of the LMOS software, or a later release.
  • Any device that you want to add to KEMP 360 Central must be located on a network that can be reached from the KEMP 360 Central instance.
  • The person performing a fresh install or upgrade of KEMP 360 Central should be familiar with network administration best practices within their organization and possess an intermediate level of general network and system administration knowledge.
  • For the best user experience, KEMP recommends using Google Chrome to access the KEMP 360 Central UI. Other browsers -- Firefox, Safari, Edge, and Internet Explorer -- are also supported.
  • If any of the LoadMasters you are adding to KEMP 360 are configured into a High Availability (HA) configuration, please see the additional configuration notes in the section Monitoring LoadMaster HA from KEMP 360 on page 5.
  • Please read the following section below before installing or upgrading:

This document applies to KEMP 360 Central. For documentation on configuring LoadMaster, LMOS release notes, information on LMOS backup archive content, or other LoadMaster-specific issues, please refer to the LoadMaster documentation from the KEMP Documentation Library.

1.2Monitoring LoadMaster HA from KEMP 360

When adding LoadMaster devices that are configured into a High Availability (HA) configuration to KEMP 360, please observe the following guidelines:

  1. Add only one device for the HA pair, using the Shared IP address. This will allow you to monitor and manage Virtual Services and other load balancing resources as well as the common configuration settings between the two HA LoadMasters.
  2. Do not add additional devices to KEMP 360 using the local IP addresses of the two LoadMasters in the HA pair. This causes duplicate logs to be synchronized to KEMP 360 and will have a negative impact on KEMP 360 performance, while providing no additional visibility into the configuration nor any additional settings that are not presented and kept in sync by the two LoadMasters via the HA Shared IP address.
  3. To ensure that you are getting email alerts for both HA units (regardless of which is the current master), configure email alerts on both LoadMasters.
  4. To edit settings that are local to each LoadMaster (e.g., interface settings, licensing), log into the LoadMaster units using the IP address of each LoadMaster in the HA pair.

In future releases, a more seamless interface between KEMP 360 and HA LoadMasters will be provided.

1.3Getting Help

If you experience issues when installing or upgrading to this release of KEMP 360 Central that can’t be resolved by consulting this document or the installation guides available from the Documentation Library, please visit the Support Web Portal to look for help from our user community, access KEMP’s Knowledge Base, or submit a support request.

To submit a support request via the Support Portal, please have your KEMP ID and password handy. After you file a request, a KEMP Support Engineer will get in touch with you promptly.

2Version 1.14

Version 1.14 of KEMP 360 Central was released in March 2017 and contains the new features, resolved issues, and known issues described in the following subsections.

2.1LMOS Version Support

With Version 1.14, KEMP360 Central is officially supports managing LoadMasters running LMOS Version 7.1.34, or a later release. Earlier releases can still be managed with KEMP360 Central, but for full support you should upgrade to at least Version 7.1.34. Note that older LMOS releases will experience the following operational limitations:

  • LMOS releases prior to 7.1.34 do not report network interface information & statistics. Because of these and other limitations present in LMOS, KEMP360 Central will perform optimally in a configuration of 50 devices or fewer running releases prior to 7.1.34.
  • In addition, LMOS releases prior to 7.1.30b report fewer overall statistics.

2.2System Sizing Limitations

In general, KEMP360 Central version 1.14 will work optimally with a configuration of up to 75 managed devices (whether they are LoadMaster or third-party ADCs, or a mix). The maximum number of managed devices that can be monitored with good UI performance also depends on the number of underlying resources (Virtual Services, SubVSs, and Real Servers) being monitored on each ADC, which is limited in this release to up to 1425 resources total across all managed devices. If concurrent users log in to KEMP360 Central, system performance will be affected and users will see increased rendering times in the UI. System scalability will be improved in subsequent releases.

The above limitations assume that all LoadMasters are running version 7.1.34 of the LMOS software, or a later version. See the section LMOS Version Support, above.

2.3New Features

KEMP 360 Central High Availability

Version 1.14 contains a beta release of High Availability (HA) for KEMP 360 Central. With this release, the following functionality is provided:

  • Two instances of KEMP 360 Central can be configured into an HA pair, using the controls located under Settings and Configuration > HA Configuration in the user interface.
  • With respect to failover, the two KEMP360 Central HA instances participate in a Master/Slave relationship:
    • One system is designated the Preferred Master unit, and this unit should be configured first. Whatever configuration exists on this unit when it is configured into HA mode will be propagated to the other unit (the Preferred Slave).
    • If the Preferred Master unit becomes unavailable, the Slave unit assumes the Master role.
    • Once the Preferred Master is available again, it will automatically re-assume the Master role (i.e., fail-back to the Master role, and the other unit will assume the Slave role again).
  • With respect to the data managed by KEMP360 central, the two units cooperate as follows:
    • Configuration changes made on either KEMP360 Central instance are reflected in the configuration and communicated to the other host.
    • Both of the KEMP360 HA instances collect system logs from managed devices. Therefore, each LoadMaster in the configuration will have both KEMP360 Central HA units as syslog targets.
    • Only the Master unit collects and generates statistics; the Master unit periodically forwards statistics to the Slave unit.

Please note that when configuring two KEMP360 Central instances into HA mode in this release, both units need to have at least one network defined for the initial synchronization to complete successfully.

Remember: Once the two units are initialized into HA mode, the configuration of the Preferred Master will be propagated to the Preferred Slave, and the Preferred Slave’s configuration will be overwritten. After initial synchronization has completed changes will be propagated in both directions.

Also see the Known Issues section on page 9.

LoadMaster Licensing & Tiered Subscriptions Summary

KEMP360 Central has been updated to provide a summary of LoadMaster traditional and tiered subscription licensing, so that KEMP360 Central administrators can quickly identify LoadMasters that are approaching or have passed a license-related expiration date.

A new Global Dashboard application, Non-Local Licenses and Subscriptions, reports the number of LoadMasters that have licenses or subscriptions that have expired or that are about to expire in 7, 30, or 60 days. These LoadMasters have been licensed using either legacy licenses or the latest tiered subscription based licenses. [Note: licenses activated via the KEMP360 Central Activation Server Local (ASL) feature are reported in a separate Local Licensing dashboard application.]

Clicking on Non-Local Licenses and Subscriptions opens a new Licensing table on the All Networks > System Configuration page. This table lists the IP Address, Name, License or Subscription, and Expiration date for all managed LoadMasters. If a license or subscription is expired, it is displayed in red text.

LoadMasters with legacy licenses will have one entry in the table. LoadMasters licensed with tiered subscription based licenses will have one entry for the license type (Standard, Enterprise, or Enterprise +) and additional entries for each subscription.

3Version 1.12

Version 1.12 of KEMP 360 Central was released in January 2017 and contains the new features, resolved issues, and known issues described in the following subsections.

3.1New Features

Log Viewer Enhancements

Click the Global Repository icon at the bottom-left corner of the UI to display the Logging page. From this page, you can search all the logs collected from all the devices that are managed by KEMP 360 and have been configured to send logs to KEMP 360. [LoadMaster, F5, NGINX, and HAProxy devices all support remote syslog; LoadMaster is configured automatically from KEMP 360 while the other devices must be configured manually.]

On the left, the time period for the log search can be set. Controls at right allow you to filter the logs for the selected time period by several new criteria:

  • Text: Type in a simple text string (this was the only criteria supported in the previous release).
  • Log Severity: Use the slider control to range of log message severities that you want to see in the search results.
  • Device IP: To filter for a single IP address, select from a list of IP addresses for all devices managed by KEMP 360. The IP addresses are organized by device type (LoadMaster, F5, NGINX, HAProxy) then by IP address. If you select a device type, then only entries from all devices of that type will be searched (e.g., all LoadMasters or all F5 devices).
  • Virtual Service IP: Select from a list of IP addresses for all virtual services managed by KEMP 360.
  • Real Server IP: Select from a list of IP addresses for all real servers managed by KEMP 360.

Global Dashboard

A new global dashboard is added that displays key information such as device, infrastructure and application health in separate panes with clear indicators. The data presented includes:

  • Device Health
  • Top 3 utilization
  • Local License Allocation
  • Log Summary
  • Virtual Service Status
  • Real Server Status
  • Administratively Disabled Services and Servers
  • WAF Statistics Summary
  • Active Connections Summary

First Time User Login Experience Improvements

When logging into a newly deployed KEMP 360, the system now prompts you automatically to add your first LoadMaster device. You can add one or more LoadMasters, optionally populating the KEMP 360 Central SMTP (email) parameters from the LoadMaster being added.

Add Device Workflow and Network Tree Organization

The workflow for adding any device (LoadMasters and 3rd-party devices) now locates your device by default in the network with the smallest address space that contains the IP address you specified for the device. If the device cannot be successfully contacted upon adding it to KEMP 360, the device is located at the bottom of the network tree, and will be moved to its appropriate location in the tree once the unit has been contacted and its configuration read by KEMP 360.

After the device is added, the default device location in the network hierarchy can be changed by the administrator by editing the device configuration. The device will remain in that location until the administrator specifically modifies it.

KEMP 360 Backup and Restore

Click the Settings and Configuration icon at the bottom-left corner of the UI and then click Backup & Restore to display the Backup and Restore control panes. The backup archive created contains a complete copy of the current running configuration, including all managed devices, services, networks, and KEMP 360 settings. The backup archive is encrypted and password-protected, and is saved locally to the system from which you launched the KEMP 360 Central user interface.

Similarly, the restore facility allows you to upload a previously created KEMP 360 backup archive from your local system and overwrite the current KEMP 360 configuration using the information in the archive.

The backup and restore facility is intended for disaster recovery – the device on which a backup archive is restored is expected to be equivalent to the device on which the archive was created with respect to network configuration and licensing. Other restrictions apply to restore operations when:

  • Restoring an archive created on a unit other than the one on which the archive was created.
  • Restoring an archive to a newly provisioned device while the device on which the archive was created is still active.
  • Restoring an archive that employs local licensing from a KEMP 360 ASL Activation Server.

For more information, see the backup and restore documentation in the KEMP 360 Central Feature Description.

KTS-2383

Fixed a problem with VS motion where the user is unable to edit the VS alternate address before copying the VS, possibly resulting in duplicate IP addresses on the target unit.

KTS-2229

Several issues related to wildcard ports on Virtual Services were present in previous releases:

  • A wildcard port specified when adding or modifying a VS returned an error.
  • An existing VS on a LoadMaster added to KEMP 360 would not be instantiated on KEMP 360.

These issues have been fixed.

KTS-2004

Andreas,

Just tested this in my lab and I was able to reproduce the issue. If you do not extract the zip file it will throw the error you are seeing.

When I extracted the zip file and just selected the PATCH, I was able to update central without a problem. If you have further issues with this please open up a support case and we can troubleshoot this further.
