A stable, scalable and cost-effective solution that helps with inbuilt scripts for easy modification
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.

Alerting precision has reduced incident response times and improved department-level network visibility
The auto-pause sensor during the maintenance window is good without any false alerts, and it prevents me from getting flooded with alerts during planned maintenance, helping department heads understand their own network usage better. It has reduced incident response time by giving clearer ownership of each alert, ensuring alerts go to the proper recipient. SNMP testers and auto-pause are among the best features of PRTG Network Monitor, which is particularly useful for different departments such as HR and finance, where alerts can be filtered accordingly. The alerting features and dashboard of PRTG Network Monitor are very helpful, especially in our industry. However, the dashboard can look cluttered on smaller screens, which is one negative aspect. PRTG Network Monitor has impacted us positively; we have stopped getting flooded with alerts during planned maintenance or unplanned outages. Compared to others, this gives specific alerts very quickly and helps department heads understand their own network usage better, thus reducing incident response time so that each alert has clear ownership.

Quotes from Members

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

Pros

"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."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"We have found the solution to be stable."
"Icinga has multiple automation and integration features. There is an API for everything and a web UI for configurations. The APIs enable you to automate tasks in Icinga. We can also use plugins to talk to the API. The Icinga Director talks to a database in the background, and you can import settings from the CMDB to all systems in Icinga."
"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."
"The most valuable feature is one that not many are even aware of, as Icinga has a self-healing event handler where if the service is down, it is automatically restarted, and you can configure the handler to take action after the critical alarm without human interaction."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"Icinga does the job and is fairly stable."
"I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server."
"We have been extremely satisfied with PRTG's capabilities overall."
"The support is fantastic."
"The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely."
"The bandwidth monitoring is a very attractive feature, it can tell you the bandwidth utilization while it is attempting to connect to the host for feedback."
"The reliability of the solution means we are doing less work trying to figure out issues and optimize systems, as it is already supplying us with the information that we need."
"PRTG gives us true visibility of the downtime of particular circuit functions. So if a circuit is up but not routing traffic, I will know with this tool. I can write a customized script for a sensor to detect specific things."
"PRTG Network Monitor is a scalable product even though there are currently restrictions in our country."
 

Cons

"We have found some problems with Nagios, and support isn't very responsive."
"At this time, the layout of the website is a bit difficult. It should be more user-friendly for changing the background and logos."
"The installation and configuration are very complex."
"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."
"In general, the product does not look good. However, it does what it is supposed to do. So, the improvements should focus on usability and UI."
"The user interface should be improved."
"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."
"I would like to see Office 365 monitoring. Essentially, it doesn't do it. I assumed not at all, but apparently it does it slightly. However, due to issues with APIs, they currently don't provide full monitoring for O365."
"There's always room for improvement. The high availability feature is good, but it's an area that PRTG could marginally improve."
"For smaller networks, I would recommend this solution. That said, if the network is complex, I would recommend a company evaluates another product instead."
"The dashboarding definitely needs improvement."
"PRTG Network Monitor could improve by having descriptions for the tab usages. The dashboards or interface could be easier to understand."
"There seems to be a big jump from the basic scan to the really thorough scan."
"PRTG would be improved if it required less memory to run."
"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."
 

Pricing and Cost Advice

"The solution is free to use."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"This is an open-source solution with paid support."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"It's an open-source solution."
"We're using the free version of Icinga."
"The product is inexpensive compared to other DBM products."
"The solution is cheap."
"All monitoring system is close to the same pricing scheme."
"The price was pretty good, very competitive."
"PRTG Network Monitor's price is a little high."
"I rate the licensing for PRTG Network Monitor an eight out of ten."
"PRTG Network Monitor is very expensive."
"We used a product called SolarWinds in the past, and its cost was high. Whereas, PRTG came in at a third of SolarWind's cost."
"If you're looking for a cost effective software I’d suggest this product."
"The price is pretty comparable."

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…
