CTO at Oic
Zabbix has high scalability.
CTO at Four Nine Agency
I would rate its scalability ten out of ten.

Room For Improvement

Nagios XI's interface is outdated, lacks scalability, needs better cloud integration, APIs, automation, and improved documentation.
SCOM needs better dashboards, lower licensing costs, easier integration, improved reporting, enhanced support, and efficient alert management.
Zabbix needs user interface, reporting, and dashboard improvements, plus better configuration, automation, documentation, scalability, and advanced monitoring features.
Many tools have poor user interfaces, making them hard to manage and navigate.
Network and Security Engineer at a educational organization with 1,001-5,000 employees
The GUI could be improved. It's a bit too basic.
Site Duty Manager at Assw
I would like to see a software-as-a-service version in Azure to eliminate the need for on-premise infrastructure.
ICT System Administrator at College of Europe
SCOM is likely to be phased out in favor of more compatible tools like Icinga for application monitoring or when moving to cloud solutions like CloudWatch and Azure.
Network Operations Center at Student Loans Company
It would be beneficial to have a summary on one single dashboard, as there are many more possibilities available.
Assistant Manager at SMS group GmbH
The only issue I can note is that it's Linux-based, and Linux documentation is not the best.
CTO at Oic
The potential and customization is a little difficult because you have to learn scripts.
Network Engineer at a computer software company with 11-50 employees

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.
AK
Assistant Manager at SMS group GmbH
Have integrated effective monitoring and seamless alerting with improved visualization capabilities
The most valuable feature of SCOM is its monitoring capability, and we have integrated SCOM with Grafana, which is a dashboarding tool. We have implemented and integrated this to create dashboarding of the SCOM monitoring system for the database, SQL, and the Linux servers we have configured in SCOM. We have created separate dashboarding for it, and the monitoring and creating rules and monitors in the management servers and management packs that SCOM provides are very useful for us. The alerting mechanism of SCOM has benefited our operations because we have modified the thresholds as per our internal requirements. We have configured threshold modifications for the CPU, memory, and especially for disk space. For routine disk space usage on the system, we have provided a separate threshold configuration.

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…
