Hello Mark and Joe,

Thank you very much for your replies. This explains the behaviour we have been seeing.

The hint to look for the Operate palette instead of the top right corner made the difference

Best regards,

Hi Panos,

You are correct in that Controller Services that are created in the top-right corner will
not be available
to Processors. These are "controller-level" services and are available only to Reporting Tasks
and other
Controller Services.

If you want to use a Controller Service for Processors, then you need to create the service
at the Process Group
level (in the Operate palette). A Controller Service that is created here is available to
any Processor in this group
and any child group. So if you want a Controller Service to be available to all Processors,
you can simply create
the Controller Service at the Root Process Group, and all child groups will then have access
to it.

Hello all,

We are using NiFi 1.0 over http without any authentication, so all our users are coming to
NiFi as anonymous.

The problem we are having is of controller services visibility. So if we create a controller
service (say database connection) from the top right option of the canvas, this is not visible
within a group of processors. Also the contrary is also true, if we create a controller service
for a group of processors, this is not visible to the rest of the canvas.

Is there a way to assign visibility for a controller service, e.g. set global visibility for
a service, so that we don’t have to recreate it in all the groups of processors that need

As a side note, we didn't have this problem with NiFi versions before 1.0.

Many thanks,
