Emmanuel Appiah Boateng - PeerSpot reviewer
Network and Security Engineer at a educational organization with 1,001-5,000 employees
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.
KamranBhatti - PeerSpot reviewer
Network Engineer at a computer software company with 11-50 employees
Helps reduce response time but has room to improve customization complexity
We are not working on simple standalone solutions like Kaspersky DDoS Protection or Hybrid Cloud Security. Once you understand Zabbix, then it is easy to customize those web pages and graphs for our customer use. It is fully automated to your requirements. Zabbix is working fine with no issues, and I am satisfied with it. We have combined Zabbix and SolarWinds. The integration works fine, and it is easy to integrate Zabbix with the IT environment. We were trying to purchase MDR (Managed Detection and Response), but we are not working on that. I don't have real experience with MDR. We are using Falcon software for that. We are working with Falcon Complete, not with Sandbox. We are not using Kaspersky for business or cloud protection. For that, we are using Zabbix CrowdStrike Falcon Complete solution. I have given this review an overall rating of 8.

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…

I think that your best bet of the two is Nagios. I would also take a look a CA Nimsoft Monitor Freemium. This will have more OOTB functionality for you sir.

ZABBIX ... of course :) We have been working with this wonderful monitoring tool since 2007 (before we had used Nagios, Openview, Whatsup, Hobbitmon, etc) and until now we haven't seen any limitations in our projects. If you need to learn a little bit more about 'how to customize ZABBIX' you can search about: - ZABBIX UserParameters; - ZABBIX pluggable modules; - ZABBIX LLD; - ZABBIX API; I think this things will help a lot to know how to extend/customize ZABBIX.
