Easy to use, and it's possible to customize the product as per the needs we may have but average multi-tenancy aspect
It's supported by the community. We use Icinga, which is not part of the Open-Source platform but is wrapped into a commercial solution from another provider, a local provider in Italy. Icinga is an open-source platform, so it is supported by the community. It's quite easy to use, and it's possible to customize the product as per the needs we may have. So it's not expensive, and it's quite a general purpose. We can easily monitor any kind of infrastructure we encounter. The ability to customize scripts and build your own queries to request information from the infrastructure elements you want to monitor. This level of personalization and customization is highly appreciated. The alerting is the same as any other monitoring platform. It's not a "wow" feature that has changed our lives, but it's perfectly adequate.

Has reduced troubleshooting time and improved issue detection through sensor alerts and team collaboration
PRTG Network Monitor can be improved because the dashboard themes feel outdated. It should be updated to a newer version for the new Gen Z customers. The notification sound options are limited unless customized. Restarting probes after Windows updates is necessary, and there should be some kind of automatic restart. The initial auto-discovery added too many unnecessary sensors, so auto-discovery should only take the necessary sensors into consideration.

Quotes from Members

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

Pros

"We have found the solution to be stable."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"Icinga does the job and is fairly stable."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"If you have a small infrastructure or a small number of devices that you want to monitor, then I think it's a good solution."
"People should know that it is simple and advanced."
"An affordable solution for small organizations to do basic network monitoring."
"I would recommend Icinga; it's an open-source solution, it's quite easy and simple to use, and checks can be run with Python code and Shell Script code."
"Network monitoring - it's able to collect lots of detailed information on network devices and network traffic."
"The real-time monitoring and alerting are its most valuable features."
"The solution is easy to manage and the reports are very accurate."
"We are using the basic PRTG that we can download for free, and PRTG is much cheaper than SolarWinds."
"I would recommend this solution because it's great for monitoring network traffic and producing reports."
"The solution has definitely saved us time and money."
"The auto-pause for sensors during maintenance windows is awesome, as there are no false alerts till now and the built-in SNMP tester tool has saved me multiple times during setups, making PRTG Network Monitor a one-stop monitoring solution for my industry."
"I like the mobility of the PRTG Network Monitor and ITOps Dashboard."
 

Cons

"The solution lacks many features important to higher-level IT management and network support."
"It is not really adequate for our current needs. It causes additional issues which we have to work around and takes us time that a better solution would not."
"It needs Trap SNMP. I saw the documentation for Zabbix, that it has its own built-in product which handles SNMP traps, and there's nothing similar in Icinga or Nagios. I think this feature is most important for me."
"Icinga’s automation could be improved."
"I think the software is quite good, but we have had problems with getting it to recognize certain areas and amend certain checks, where we needed so we would have to create backend scripts for those checks. Though, being open source, it has the support to create backend scripts, it would be better to have these scripts in-built."
"Sometimes, it is very hard to keep an overview of what's happening."
"Icinga is a complex solution that's hard to learn. It's a powerful product for monitoring, but new users will have a hard time figuring out what to do."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"Having a Unix implementation or Unix installation could be an improvement. Right now, it's based just on Windows, and that's a problem for some customers."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."
"Technical support is an area with concerns in PRTG Network Monitor, where improvements are required."
"I would like to see more updates available in this solution."
"PRTG's documentation could be improved."
"The most significant disadvantage of PRTG Network Monitor is that the dashboard for NetFlow is not user-friendly at all."
"The technical support could respond a little bit quicker."
 

Pricing and Cost Advice

"The solution is free to use."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The solution is cheap."
"It's an open-source solution."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"We're using the free version of Icinga."
"This is an open-source solution with paid support."
"The product is inexpensive compared to other DBM products."
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
"We bought a license for 4000 sensors."
"The pricing is reasonable for the features provided."
"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"If you're looking for a cost effective software I’d suggest this product."
"We are satisfied with the price."
"The price of PRTG Network Monitor is reasonable."

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…
