Metered Licensing Management

1 Introduction

Metered Enterprise Licensing Agreement (MELA) offers enterprises and service providers a flexible way to license their application delivery resources. MELA meets the demands for flexible application capacity and the requirements of environments such as cloud for multiple Application Delivery Controller (ADC) instances. By using this model, an organization subscribes to a defined monthly capacity that can be distributed across unlimited on-demand ADC instances deployed between multiple cloud and on-premises environments. MELA is a subscription service and enables organizations to pay-as-you-grow with an application delivery infrastructure that is flexible, cost-effective, scalable and always right-sized.

By using the KEMP 360 Central Activation Server functionality, you can quickly and easily activate KEMP LoadMaster Virtual Appliances using MELA. This licensing method enables flexible operational and deployment models to be supported instead of the standard single LoadMaster licensing model.

1.1 Document Purpose

The aim of this document is to walk you through a successful deployment of MELA from purchasing a MELA contract from KEMP to activating the LoadMaster using KEMP 360 Central.

1.2 Intended Audience

This document is intended for MELA customers who want to find out how to deploy their KEMP 360 Central and LoadMaster instances.

When we refer to KEMP 360 Central and LoadMasters throughout this document, we are referring to the MELA image.

2 Register for a KEMP ID

A KEMP ID is required for licensing. The first stage in doing a successful deployment of MELA is to register for a KEMP ID (if you do not already have one). To register for a KEMP ID, perform the following steps:

1. Go to the KEMP registration page at https://kemptechnologies.com/kemp-id-registration/

2. Complete the form as required.

Ensure you enter a valid email address. The validation email and license information is sent to this email address.

3. Make note of your password because it is required to activate the account.

4. Click Create a KEMP ID. An email is sent from KEMP to the address specified in the form.

5. Open the email and click Confirm to open the validation screen.

If you do not activate the account within 24 hours of registering, the record is deleted and you must register again.

6. Enter the password that you specified on the registration form.

7. Click Activate Now. You then receive a further confirmation email to inform you that your KEMP ID is now active.

8. Contact KEMP to convert your KEMP ID to a MELA KEMP ID.

This KEMP account can now be used to activate products.

2.1 Purchase a MELA Contract from KEMP

Contact your KEMP representative directly to purchase a MELA contract.

This is important because you must have a MELA contract before you can use MELA licensing and functionality.

After you do this, KEMP sends you a contract ID.

2.2 Reset your KEMP ID Password

If you do not know the password for your KEMP ID account, you can reset it. To reset the KEMP ID password, follow the steps below:

1. Go to the reset password page: http://kemptechnologies.com/support/reset-password

2. Enter your KEMP ID.

3. Click the Submit button. An email is sent to the address specified.

4. Click the link in the email.

5. Enter the new password in both the Password and Retype Password fields.

6. Click Reset. A message appears informing you that the password is successfully changed.

2.3 Changing your KEMP ID Email Address

4.4 Licensing Complete

Having successfully licensed your KEMP 360 MELA, the initial configuration is now complete. For further information, including instructions on how to add a network to KEMP 360 Central, refer to the KEMP 360 Central Feature Description

5 Deploy a MELA LoadMaster

Refer to the relevant LoadMaster installation guide depending on your environment. You can find all documents at https://kemptechnologies.com/loadmaster-documentation/.

When you get to the steps for licensing your LoadMaster, refer back to this document because the licensing steps differ when using MELA.

6 License a LoadMaster Using KEMP 360 Central Activation Server

image2.png

When an Activation Server LoadMaster is initially deployed, a screen appears asking if you want to use online licensing or local activation.

image3.png

When Local Activation is selected, a screen (similar to the one above) appears. If this screen does not appear, you are not using the correct version of the LoadMaster. Please contact a KEMP representative if this is the case.

The KEMP 360 Central (with Activation Server enabled) details must be configured in the LoadMaster web User Interface (UI) so the LoadMaster can contact KEMP 360 Central. Follow the steps below to activate the LoadMaster:

1. Type the IP address of KEMP 360 Central in the IP address text box and click Set Address.

2. Type the Port to access KEMP 360 Central on and click Set Port.

3. Alternatively, you can type the Hostname of KEMP 360 Central and click Set Hostname.

If using Azure - the internal IP address and host name are found in the Dashboard screen of the KEMP 360 Central instance. The hostname is based on the instance name, which is specified when originally creating the instance. If you are not using Azure, the default hostname is K360Central.

4. Click Activate. The available license types are displayed.

5. Select the relevant license type and click Continue.

6. The LoadMaster is now licensed against the Activation Server on KEMP 360 Central.

7 Activate the LoadMaster in MELA KEMP 360 Central

The LoadMaster must be activated within MELA KEMP 360 Central. To do this, complete the following steps in KEMP 360 Central:

image4.png

1. Click the cloud icon on the left then click All Networks.

image5.png

2. Select the relevant LoadMaster.

image29.png

3. Click the Edit icon in the bottom-left.

image7.png

4. Enter the Public Access Address for KEMP 360 Central.

5. Enter the Port used to communicate with the LoadMaster.

6. Type a nickname in the Nickname field (if required).

7. Enter the Username and Password used to access the LoadMaster.

8. Type an Alternative WUI Access address in the field provided (this is optional).

9. Click Apply.

image8.png

LoadMasters with a blue icon indicate that the MELA LoadMaster was licensed using the Activation Server functionality.

image9.png

KEMP 360 Central keeps track of the activated systems by maintaining a list of activated VLMs and MAC addresses. This list can be accessed by clicking the cog icon and selecting Metered Licensing Management. Ensure the MAC addresses of the VLMs are unique by checking the VLM hardware options through a hypervisor. This enables proper tracking of the VLMs. If the license limit of VLMs is reached, KEMP 360 Central will not activate any more VLMs. If the limit is reached, a warning message appears on screen and an existing active VLM instance must be unlicensed (deregistered) before a new VLM can be licensed.

The LoadMaster periodically checks for the presence of the Activation Server (KEMP 360 Central). If the Activation Server cannot be found, or there are any errors, an error message is displayed and the VLM stops working after a predetermined length of time based on your agreement with KEMP. If an activation check fails, an error message appears on the LoadMaster home screen indicating that activation failed.

8 Metered Licensing Management

There are three tabs in the Metered Licensing Management section: Activations, Metered Enterprise Licensing Agreement (MELA) Report, and Licenses.

 

8.1 Activations

The Activations tab opens when you click Metered Licensing Management.

image10.png

The chart displays the number of current active ASL activations. Below the chart you can view the maximum number of ASL licenses available (50 in this case).

The last two columns show: the license type that KEMP 360 Central provided and was installed on the LoadMaster; and the platform on which it is running. Unlike previous releases of KEMP 360 Central, since Version 1.18, you can license LoadMasters running on any hypervisor platform, not just the one on which KEMP 360 Central is running.

Any changes you make to the license in the LoadMaster are reflected on this screen.

When using LoadMaster HA pairs, the shared IP address is not counted as an activation in MELA and is not reported on.

8.2 MELA Report

In this section, you can view a report displaying the number of active ASL instances. This report can be filtered by using a date range. To access the Metered Enterprise Licensing Agreement (MELA) report section, click the Settings and Configuration icon, click Metered Licensing Management, and click MELA Report. To view a graphical representation of the report, click View.

Reports can also be downloaded in zip format by selecting the Download Summary checkbox and clicking Download. The Download Summary checkbox determines the behavior of the Download button. When checked, a zip file is downloaded containing several data files, including the peak statistics values for each day. When unchecked, a single file is downloaded containing minute-by-minute statistics. The downloaded zip file contains three CSV files:

  • asl: An event report that displays events and the number of active ASL instances at the time of the event. The events recorded are as follows:
    • Activation: An ASL LoadMaster has been activated using this KEMP 360 Central instance
    • Deactivation: An ASL LoadMaster on this KEMP 360 Central instance has been deactivated
    • Sync (Discrepancy): KEMP 360 Central has detected a discrepancy between the previously recorded instance count and the actual instance count, and has corrected the error
    • Sync (No Discrepancy): No discrepancy has been detected. In the absence of other ASL events, this serves as the instance count for any given day. The sync task is performed in the following circumstances:
      • If KEMP 360 Central is upgraded to version 1.6 or later
      • Daily at 12 pm
  • devices: A report displaying the currently active devices on KEMP 360 Central including the ID, device nickname, and device IP address.
  • ssl_tps: An SSL Transactions Per Second (TPS) report.
  • vs_bytes: A report displaying the number of Virtual Service bytes transferred.

These reports include minute-by-minute data from 00.00 hours of the start date selected up to the minute the report is run. To get a full report, leave the Download Summary check box cleared. To get a summarized report, select the Download Summary check box. This report produces an archive containing three files:

  • Daily peak TPS per ASL LoadMaster per day
  • Daily peak throughput (bytes per second) per ASL LoadMaster per day
  • All ASL activations or deactivations (and the number of active ASL instances at the time)

To view a MELA Report for a specific date range, select the date range then click View.

This report provides you with a graphical representation of the information such as the maximum number of ASL instances that were recorded during the report period, the peak number (top five devices) of SSL transactions, and the peak throughput (top five devices). The report displays usage data, which enables you to examine and validate the periodic billing statements you receive from KEMP for metered licensing.

If you select the Upload usage report to KEMP checkbox, a report is also sent to KEMP with the same data but different time profiles. If the automatic reporting fails, you can click Retry Upload.

image11.png

image12.png

image13.png

image14.png

image15.png

image16.png

There is also a table under the graph that displays the information in tabular format. You can also view detailed individual graphs on the peak SSL transactions per second and peak throughput of all devices.

You can also view what license is assigned in the Event Type column in the ASL Instances table as shown in the image below.

image17.png

 

8.3 Licenses

This tab displays the different license types that are available, including the supported VLM types.

image18.png

From the figure, you can see that there are four columns: License Type, Supported VLM Types, Max Activations, and Activations.

The Max Activations column indicates the total number of activations allowed across all license types, which is 50 in this case. Because two are already activated, it means there are 48 licenses left.

 

When you change a license on the LoadMaster using ASL, the LoadMaster is not automatically rebooted. It must be rebooted manually to refresh the license.

To kill an ASL license from KEMP 360 Central, click the Network and Device Administration icon, select the device in the left frame and click the delete (minus) icon at the bottom of the left tree. A ‘Kill ASL Instance’ popup appears asking for confirmation. This both removes the device from KEMP 360 Central and deallocates the activated license that was used by the unit.

9 Troubleshooting

If you try to license and there are issues, a number of checks are performed automatically and the results and associated error message are displayed.

image19.png

These checks perform the following tasks:

  • Ping Default Gateway
  • Ping DNS Servers
  • Ping Licensing Server
  • Ping Activation Server

You can also manually check the KEMP 360 Central debug log. If there are no entries relating to Activation Server, it means the connection to the Activation Server has failed.
