SI
A suitable choice for unified and efficient infrastructure monitoring across diverse environments providing user-friendly GUI, cost-effectiveness, and versatility
We use it for this specific client, they've deployed multiple instances of it across various locations to facilitate monitoring. To effectively monitor their infrastructure, it seems necessary to implement additional monitoring solutions for all three types of devices they have Nagios Fusion…
B Ahmed - PeerSpot reviewer
Enables seamless global client monitoring with reliable remote connectivity
I use the solution to provide a perfect environment for remote connectivity with my clients. Many tools that I require for system maintenance are included. I can easily monitor all of my clients throughout the world I did not give much thought to it, however, improvements could be made to Zabbix.…

Quotes from Members

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

Pros

"It is easier for client installation, and the configurations are doable even for a newcomer in the field."
"Nagios Fusion version 12.8 excels in user-friendly GUI design, cost-effectiveness, and ease of deployment."
"Being open source lets us customize it for our monitoring needs, saving us money."
"It's very easy to manage and monitor it."
"It is a great product. The SNMP protocol tracking feature is good. I really like how it tracks SNMP. The alerts are also great."
"Simple network monitoring that is easy to install and manage."
"It can send messages to our ticketing system."
"I use the solution to provide a perfect environment for remote connectivity with my clients."
"The template system in Zabbix is very beneficial as it saves time in configuration."
"Dashboard and the customization of the items and triggers are the most valuable features."
"The most valuable features in Zabbix are those that help us overcome bottlenecks in CPU usage, as well as reduce memory delay. I know that we have only reached the tip of the iceberg of what Zabbix's features can do for us, and we have not used all of them yet."
"Zabbix is very easy to implement."
 

Cons

"Adding application performance monitoring to the product alongside infrastructure monitoring would make it a more complete and useful solution."
"In future iterations of this solution, there is a desire for more seamless integration with other monitoring software."
"There are some bugs, although not that many. There are some situations where the solution is not stable but the number of problems is not very high."
"Nagios Fusion should include a 'remember me' option when logging in, so we don't need to enter a username and password every time."
"There's a small module of APM, however, it is not an enhanced version. People usually ask for a full-fledged APM solution."
"I think the reporting part of Zabbix can be improved in terms of more user-friendly graphics to display the collected data. Many simple users who don't know how to use Zabbix properly might get confused by the reporting, although at the same time it is very versatile for my company."
"The documentation gets a bit messy between versions and is not too detailed, which is a bit painful for first-timers, especially when they run into issues."
"Its UI needs to be improved a little bit more so that an end-user is also able to handle it. I can handle it, but others should also be able to handle it in a better way. It becomes complex when we are growing and need to add proxies. We need more scalability features and documentation for different use cases. A lot of articles are available, but they need to be in proper documentation. For example, when you have thousands of servers that have to be monitored in different regions of the world, there should be some kind of documentation to describe how you can create proxies and add them. Sometimes, when you are using the database, it can get overloaded. When the network is growing, the number of transactions becomes very high, and the database gets overloaded. There should be information about how to reduce the load on the MySQL database, which is what Zabbix is using. The market is growing a lot, and it should be enhanced for a lot more things. We are currently bringing enhancements at our end for different use cases. For example, when dockerization is going on, how can we check the logs inside the Dockers. We should also be able to monitor and check the number of logins and add features such as SSO login and two-factor authentication as a protocol. These are the security features and concerns that we have to deal with. Currently, we are developing modules to add features to Zabbix, but they should also work on these features."
"One of the things we don't like is that Zabbix has a license structure with a price that is high compared to the competition. It's very high, for example, compared to something like Microsoft Teams."
"There are a lot of areas for improvement, specifically in the dashboards and reports functionalities."
"Sometimes, the documentation is a little bit written in Estonia – a country in Europe. The language barrier and translation to English can sometimes make it difficult to understand what they're trying to get at. It's just a language thing."
"Implementing Zabbix is difficult. I've deployed many solutions over the years, and Zabbix is the hardest to implement. You have to do some development to get it to work with IBM, Micro Focus, or HP products."
 

Pricing and Cost Advice

"The pricing is quite reasonable, especially when compared to the broader market."
"This is an open-source solution that can be used free of charge."
"This is an open-source solution that can be used free of charge."
"We pay the subscription for support by year."
"If you have 20,000 hosts, the support costs around €95,000 for a year."
"It's free software released under the GNU/GPL license."
"It is free, which allows us to reduce costs."
"Zabbix is free but if you use it in production then you have to pay for it."
"The solution is free to use but they offer support as a paid service. If you can go read the manuals and do the fine-tuning based on your needs, you do not need to pay anything and you will have a full solution."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
