Good end-to-end voice quality monitoring and offers valuable features
The solution should have automatic baseline detection. On the per hour, per base, per week. That's usually the best. And on a per individual CI level. I know that they're working on it and when that's available then we will definitely implement it because it will reduce the effort we need to maintain all the products. Right now we have to set thresholds for every location, and it needs to be actually dynamic so if we have better thresholding, we'll have faster alarms across all our locations. We won't have to expend effort on it by resetting or checking them on a regular basis.

Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.
