Featured Reviews

Faiz Fortune - PeerSpot reviewer
Project Engineer at Moksh Tech
Automated monitoring has streamlined time tracking and project management across all clients
I think the most valuable feature of ConnectWise RMM is scheduling my time with clients and capturing my times with them. Time management is key for my workflow. It helps with keeping track of all our clients and all the devices, so ConnectWise RMM has been quite helpful in managing my IT environment overall. Automated patch management in ConnectWise RMM has made everything streamlined, allowing me to concentrate on more important tasks. I can run my automations and ensure that they go through every server, every cloud infrastructure, and every client. I've observed that with ConnectWise RMM, capturing my times used to be quite an issue when working with overseas countries, but now it's much easier, and I can monitor everything I'm doing in real-time.

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.
