Monitors well with Citrix, stable, and the support is very responsive
It looks like it is easy to scale, but I don't know how far it can go out. We are only a 300, or 400 person company. We are not terribly large. It looks like it should be able to scale up until 10,000 at least. There are two users in the company who use this solution, I use it, and the helpdesk.

Monitoring solution provides comprehensive visibility across IT infrastructure
The good thing about Nagios Core is it covers everything. Everything in the IT domain, you can monitor anything. You can even monitor printers, the ports of printers, Core workstations, and storage. You can monitor the workflow Core and the utilization of computes. If you want to grasp everything of your IT equipment on a single interface, you can use Nagios. It's the best one. It provides dashboards, and you can also configure your emails and alerts with it. If something is critical, you can configure it to notify via emails. It has a very handy dashboard, providing live alerts and visibility for everything.
