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

"Icinga2 was designed to delegate, distribute and balance tasks between several nodes."
"I use it for monitoring infrastructure and it was very good for that issue."
"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."
"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."
"People should know that it is simple and advanced."
"Macros and the ability to connect it to Google Maps are valuable features."
"Icinga does the job and is fairly stable."
"The most valuable feature of PRTG Network Monitor is real-time monitoring."
"The remote probes are very useful. They allow us to provide a reference across different areas in the network. In trying to localize issues, that's very useful."
"The solution has definitely saved us time and money."
"PRTG Network Monitor is easy to set up."
"The tool is integrated with our email for the alerts."
"PRTG Network Monitor is a very stable product."
"The scalability is good, you can improve a remote host or the clustering, giving you the flexibility to monitor another infrastructure remotely."
"We can see trends for a lot of different things, such as hard drive space and bandwidth usage. We can see and plan for the future by knowing, "We're sort of at 75% capacity now. In three months time, we know we're going to be up to 90%,so we need to plan ahead for it, getting upgrades booked in place." Since things like this take time and effort, it's handy to see trends into the future of where our company is going."
 

Cons

"The solution lacks many features important to higher-level IT management and network support."
"Icinga’s automation could be improved."
"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."
"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 user interface should be improved."
"The installation and configuration are very complex."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"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."
"There's always room for improvement. The high availability feature is good, but it's an area that PRTG could marginally improve. For example, in PRTG, both servers have a different IP, but it would make things a lot easier if they were bound by a single IP."
"When it comes to third-party integration, one of the things we were looking at was putting some sensors onto our firewall, for instance. If there were a little bit more documentation and some step-by-step guides around that, that would be useful for us."
"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."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"PRTG Network Monitor needs to enhance network performance monitoring. Moving towards observability, similar to what Datadog offers, could be beneficial."
"PRTG Network Monitor is okay to use, but you need some time to analyze the data, so this could be an area for improvement."
"The desktop app is the one area where it do with some improvement. From a user's perspective, I would like to be able to get more out of the desktop app as opposed to where we are now with it."

"The product is inexpensive compared to other DBM products."
"This is an open-source solution with paid support."
