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."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"People should know that it is simple and advanced."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"I use it for monitoring infrastructure and it was very good for that issue."
"I like the ability to amend and adjust things really easily, which is useful in a case where you could make it auto-discover and then set a template to say all of these applications or servers under this template have an automatic threshold set that you’d set up manually."
"The best thing about the solution is how it highlights errors, the issues, and what needs my attention. The solution directs me to areas that I should look for first."
"It has made our infrastructure more reliable."
"It will take care of all your monitoring needs, pretty much, but just be conscious of scale."
"Our users perceive it as our being able to provide a very high level of service because we're avoiding situations where they suffer downtime."
"The solution has excellent redundant features."
"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 and can write a customized script for a sensor to detect specific things."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
"Every monitoring session features similar capabilities."
"The network visualization helps us to drill down deeper."
 

Cons

"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"The user interface should be improved."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"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."
"We have found some problems with Nagios, and support isn't very responsive."
"Sometimes, it is very hard to keep an overview of what's happening."
"The connection between Icinga and Icinga Web."
"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."
"Technical support is an area with concerns in PRTG Network Monitor, where improvements are required."
"Other monitoring tools that I have used are easier to use."
"If they are looking for complex reports, I will say stay away from this product."
"PRTG could use reporting tools and mobile alert tools. It should be easier to diagnose and respond to problems from a mobile device on the go."
"The product could be improved by being cross-platform friendly."
"There seems to be a big jump from the basic scan to the really thorough scan."
"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."
"The reporting features look very technical and that can be improved."
 

Pricing and Cost Advice

"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
"PRTG Network Monitor is not that expensive, so I like it cost-wise. There's no additional cost apart from the standard licensing fees. On a scale of one to five, with one being the cheapest and five being the most expensive, I would rate the cost of PRTG Network Monitor a two."
"On a yearly basis, I believe it's between £1,200 and £1,500."
"Because we are only on the free version, we have a limited number of sensors. Therefore, we are not monitoring as much as we want to be to obtain historical information."
"PRTG Network Monitor is cheap."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"

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…
