Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product.

The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more.

The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it.

We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios.
