Room For Improvement

Featured Reviews

Charles A - PeerSpot reviewer
Deputy Director at Access Healthcare Services Pvt Ltd
Reporting features improve operational efficiency while weekend support needs enhancement
Support is moderate and needs improvement, especially during weekends when technicians perform upgrades. During weekends, they need to provide more support to ensure a smooth transition. There is a call for ManageEngine OpManager to scale better in automation and AI functionality. Although the product stability is good, support enhancement is necessary to enable better planning for upgrades and maintenance activities.

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.
