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.

The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."

"The ROI is very good."
"Nagios XI helped me to draw the network and check for system failures."
"The alerting system is very effective."
"This solution has improved our ability to determine the source of a connection failure in our network, and now we are able to monitor the service provider's router and make that determination."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."

Cons

"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"We'd like to see more integration capabilities."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."

"Reporting items needs more improvement and need to be more flexible based on customer needs."
"There's no convenient way to manage notes as the only way is to manage them through the database."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
"The price for Pandora FMS is expensive."
"An update to the Android app would be appreciated."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
