Frequently Asked Questions

I have a question about iTop, where can I find more information?

All the information you need can be found on Combodo’s website: . You will find some general information along with the online demo and professional services details.

What is the minimum iTop version for using the Hub?

What is an extension?

An extension is a module adding functionalities to your iTop. iTop is a standalone application and work perfectly on its own whereas extensions are only meant to be used with iTop.

How do I register my instance in the Hub?

You can only register instances running 2.4.1 or above. From those versions a new menu iTop Hub / Connect to iTop Hub allow you to visualize and deploy automatically extensions on your instance. and detect already installed extensions, those acquired through the Hub and the others.

It's a good practice to connect to iTop Hub from your instance after iTop upgrade and extension manual installation, in order to actualize installed extensions information and recompute extensions compatibility

How many instances of iTop can I manage with the hub?

You can manage as many instances as you like. However, iTop Hub is not meant to be used for multiples clients and instances. If you want to benefit from an optimized user experience, you shouldn’t register more than 3 instances. A higher number would deteriorate your experience.

What is the license for the extensions?

  • you have several iTop instances pointing to the same database (if you run a cluster of servers)

How do I remove an extension?

iTop does not provide a way to remove an extension once this extension has been installed. This is why it is recommended to always test new extensions on a test/staging environment.

The simpler way to remove an extension is to restore a backup made before the installation of the extension.

If you cannot restore such a backup, you can still manually remove an extension by:

  1. Removing the corresponding folder from the data/production-modules folder of iTop,
  2. Launching again the setup program (make sure that the configuration file is not read-only, then point your browser to /setup),
  3. Cleaning the database (schema and data) from the alterations provided by the removed extension.
