KL
A user-friendly solution that is easy to install and improves visibility
I would like to see improvements made to the user guide. From my personal experience, it is helpful to see a list of steps describing what to do next in different situations. An example is what to do and what to back up in the case of certain types of failure. There are also cases where a customer can't understand specific features. Enhancements to the user guide would be helpful for this. More features for network fragmentation would be helpful.

Quotes from Members

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

Pros

"One of the valuable features is the packet decoding."
"vSTREAM gives us better visibility and reporting about our network infrastructure, allowing for cost-optimization."
"The template system in Zabbix is very beneficial as it saves time in configuration."
"Simple network monitoring that is easy to install and manage."
"The solution is open-source, easy to manage, and user-friendly making it easy for anyone to use."
"The solution allows for good integration with other products."
"The initial setup, while not simple, is easier than other products."
"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."
"The most valuable feature is the monitoring of virtual machines."
"It has good graphs of what is going on within the operating system.​"
 

Cons

"I would like to see improvements made to the user guide."
"I would like for it to have a smaller footprint of the virtual appliance and better performance."
"Room for improvement exists in filtering in the packet decode."
"The only issue I can note is that it's Linux-based, and Linux documentation is not the best."
"The product delivers false positives during reporting because of flapping. Other reasonably priced alternatives may have better performance."
"I am having difficulties connecting it to Grafana, as well as some of the other plugins like Kibana."
"The user interface could be a bit better. They could update it a bit."
"An area for improvement would be the ease of doing aggregation from the value or different devices."
"The user interface could be better."
"In terms of user-friendliness, large maps could be more interactive. We should be able to click on some areas and move some objects. It would make it simpler to see things while analyzing some dedicated parameters."
"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."
 

Pricing and Cost Advice

"Licensing is quite expensive."
"My manager is very happy because it doesn't cost anything."
"I use the tool's free version."
"Zabbix is an open-source tool, and it's free to use."
"We’re using the free version, which covers all our current needs."
"The tool's licensing is good."
"There is no license but we need to pay for support."
"Zabbix and Grafana are both open source products, we only needed to go to their website and download the application and we began to use them. The solutions are free."
"Zabbix is free but if you use it in production then you have to pay for it."
