NetFlow monitoring has improved operations but needs better configurations
For the implementation part, I am facing issues when configuring the business view. When I create the business view, I experience problems with the port interface. When I add the interface, I am confused about which interface is connected to which endpoint. If identifying the interface was easier, it would take less time to configure. Another issue is with threshold values; sometimes, it shows kilobytes (kB) while our threshold is set to gigabytes. This can be confusing. Improving this aspect would be beneficial. In URL monitoring, there is room for enhancement.

Effective alerting enhances network monitoring experience with an easy setup
We love Nagios XI due to the fact that JPS Web is very useful. JPS monitors the modem and performs switching, monitoring the computer, and performing switching. We implement some applications and traffic monitoring. The alerting system is very effective. For instance, if we have an alarm on some RAM storage if the traffic is cut or dropped.
ASM Naushad Alam - PeerSpot reviewer
Allows any number of customizations but lacks functionality for finding root causes
We have not yet purchased the commercial version so have a lack of technical ability. We do not yet fully know the key points or key features of the solution. We just use what we use along with WhatsUp Gold. Based on our use only, stability is rated a seven out of ten.

Quotes from Members

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

Pros

"It helps us a lot for monitoring our servers in one console, instead of going to individual servers."
"The solution gives pretty good network visibility. I am also impressed with it's monitoring."
"The most valuable feature is the network-related reporting."
"Monitoring is the most valuable feature of this solution."
"I liked Network Configuration Manager. They had some pretty decent features there, and they also had pretty good monitoring and alerts."
"The dashboard, versatility and larger horizon are valuable."
"I like being able to push configurations to multiple devices. If you have the same configurations for all the branches, it's easier to use ManageEngine OpManager and push configurations at once rather than individually pushing them to each device."
"The integration with the firewall monitoring, the security monitoring, is great."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"I can monitor a software made in-house to software of bigger companies."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The dashboard allows you to see what's going on in the overall system."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"An excellent solution that is easy and intuitive to implement."
"Every new asset placed in the environment can be automatically detected, predicting human failures."
"The features I found most valuable are the user interface and a wide range of network devices that are easy to configure."
"Zabbix is a cost-effective solution. We're a small organization with a few dozen devices to monitor, and it was available for free. We can see what we need. We haven't done an in-depth analysis on it, but we're currently okay with the product."
"Simple network monitoring that is easy to install and manage."
"It meets my organizational needs. It's pretty easy to use."
"We like the user-interface for this solution, which makes it an easy to use tool."
"There is a problems page that shows us every warning or problem that occurs on our VMs globally. The map screen is also really useful because this is something that was missing. I don't know every other tool in the market. So, I don't know if this is a good point of only Zabbix, or other tools are also doing it, but from my point of view, this is the most useful page that I use, along with the problems page that efficiently lists the problem, recovery time, ending hours, starting hours, and so on."
"Templates are good. We download them from the official Zabbix site or the community. If the information we need isn't available, we create custom templates based on client requirements."
 

Cons

"We would like the solution's customize and build functionality to be more user-friendly."
"OpManager is slow but that just might be the server we have it on. I don't think that's the problem but I don't do the server. But it is slow. When you're interacting with it, it could be more nimble and could be faster."
"The pricing of the solution is high. They should work to adjust the pricing model to see if they can help reduce costs."
"It is sometimes difficult to manage the user interface. It can get very complicated."
"The dashboard has some limitations and should be more user-friendly."
"We would like link monitoring included. At times we need to monitor those specific links closely."
"We get a lot of false alerts."
"The licensing for this solution is not straightforward and should be improved."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"The product does not have SAP monitoring."
"We'd like to see more integration capabilities."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"The reporting structure could be more streamlined."
"The installation and monitoring need improvement."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"The reporting features need improvement, especially detailed inventory reporting. Since it's freeware, reporting may not be a major focus."
"When we have a problem, we have to do a lot of research to solve it."
"If Zabbix had a better dashboard then it would be nice."
"We would like to see the addition of automatic push functionality to this product. This would save time when monitoring our servers and networks as, at present, we have to manually install the Zabbix agent on any hardware to be monitored."
"The dashboard and the graph section could be a little bit more professional."
"The initial setup could be complex if you don't have templates. If creating templates from scratch, it's quite difficult, but if you are using already pre-created templates and setups for your needs, it looks very good."
"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."
"Its UI should be improved. They did some improvements in version 5, but it could benefit from some more work. Its integrations should also be improved. They've been active for one year, and they seem to have noticed that. It has new integrations, but it could benefit from more integrations. As far as I know, there is no model to push statistics, metrics, or events towards Zabbix. This type of API isn't yet there, whereas some other tools provide an API for this."

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…
