FAQ

Yes, you can install as many discovery servers as you want as long as the total number of devices does not exceed the total number of devices purchased.

We are pleased to generate a demo license for more than 25 devices for a fixed period for free! This allows you to test our software intensely in your network.

First, generate a license request file by opening the licensing dialog from the Help > License Info menu. Click on the “Request License” button and save the license request file on your hard drive. After having ordered the software, send this file to our Sales (sales@jdisc.com).

You have free support during the evaluation phase. So feel free to submit your questions to our support ticketing system. On request, we will also review your configuration and data during a short online session (usually 30 minutes to one hour) at no cost..

Please let us know in this email how many devices per operating system you do have in your network. This does not need to be a concrete number. A rough estimation is absolutely sufficient:

1. Number of Unix systems (HP-UX, AIX, Solaris)
2. Number of computers with Linux, VMWare, MAC OS X
3. Number of switches and routers and of computers with a Windows operating system
4. Number of any other devices (such as network printers, scanners, …)

We will sign the license and return it to you. Save the license.txt file in the installation directory, overwriting the existing file.

Restart the JDisc Discovery Windows service in order to reload the license.

Finally, check the license status from Help > License Info.

Many organizations face the same challenge: IT environments grow over time, new systems are added, old ones are retired, and the exact number of devices is often unknown. That is why JDisc Discovery uses a flexible credit-based licensing model instead of rigid per-device licensing.

How the Credit System Works

JDisc Discovery is licensed using credits. Each discovered device consumes a certain number of credits based on its device type or operating system. Whether a system is a physical machine or a virtual machine does not matter.

Devices without an IP address do not require any credits. This includes monitors, webcams, and similar peripherals. Docker containers and other container technologies also do not consume credits.

Maximum Flexibility for Your Organization

A license includes a defined number of credits. These credits can be used for any supported devices within your network. If devices are removed from the JDisc database, the associated credits become available again and can be assigned to other systems.

This allows your license to adapt to changes in your IT environment. Whether you add new systems, replace existing hardware, or restructure parts of your organization, your credits remain flexible and reusable.

Easily Scalable Licensing

Your licensing requirements may change over time. For this reason, JDisc licenses can be expanded at any time by adding additional credits.

If your long-term requirements decrease, the license can also be reduced at the next renewal period. This can be particularly useful after organizational changes, such as the sale of business units or subsidiaries.

Not Sure How Many Credits You Need?

This is a very common situation. Many organizations do not have a complete overview of their IT assets before performing their first inventory. As a result, determining the appropriate license size can be difficult.

To solve this challenge, we offer an extended evaluation license that allows you to scan your entire network.

This provides two important benefits:

1. You can verify that JDisc Discovery meets your technical and operational requirements.
2. You can accurately determine your licensing needs because all devices in your environment have been discovered and classified.

This gives you a complete overview of your IT infrastructure and provides a reliable basis for sizing your future license.

Transparent Licensing Without Surprises

The JDisc credit system allows you to license exactly the systems you need to manage. The allocation of credits is transparent, easy to understand, and highly flexible. This creates a fair and predictable licensing model that grows with your organization.

Rules for the licenses:

• Every device with an IP address (including virtual machines) counts as one device
• Devices with multiple IP addresses (e.g. routers) count as one device
• Management boards for servers count as separate devices
• For virtual machines the respective OS counts

However, there are some exceptions to those rules:

• Devices that are not identified do not count for the license (Unidentified devices, unknown SNMP devices)
• Devices without an IP address (local printers, monitors, etc.)

JDisc Discovery’s device type filter can already exclude those devices that are not relevant for the licensing at the start. This saves you license cost, discovery time and network bandwidth!

We offer different license models serving your purpose best:

1. Perpetual license
   A perpetual license can be purchased once and has no time limit. Our optional support contract allows you to keep the software up-to-date. This license model is useful for IT organizations that plan to use our software on an ongoing basis.
2. Project license
   A project license is useful for IT service providers or IT organizations, if the software is used only for the duration of a single project. Project licenses can be purchased on a monthly basis and are a cost-effective alternative to the perpetual license or annual subscription.
3. Annual subscription
   In case the purchasing costs exceed your budget or you prefer a yearly fee, our annual subscription might be right choice for you!
