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

"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."
"Macros and the ability to connect it to Google Maps are valuable features."
"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."
"People should know that it is simple and advanced."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"The apply rules feature saves a lot of time."
"We monitor all, starting from UPS to international mail chains."
"Icinga does the job and is fairly stable."
"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."
"The solution has benefited our organization by showing us when devices are up and when you are down, and we can do an analysis on the availability of the resources."
"The initial setup was surprisingly easy, the way the menus are all laid out."
"PRTG Network Monitor is perhaps the most accurate tool we have used to monitor the capacity of the WAN connection."
"PRTG is simple to manage. First, you can create a template for a device, then apply it to hundreds of similar devices. That's a great advantage."
"Stable solution for monitoring networks and bandwidth, with multiple functions and features such as NetFlow Collector, graphical monitoring, etc."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"This solution makes it easy to group devices, and it is easy when it comes to dependencies of devices, so if your router goes down, the three or four switches behind it will automatically be paused so that you don't get multiple alerts."
 

Cons

"The installation and configuration are very complex."
"We have found some problems with Nagios, and support isn't very responsive."
"The tool currently fails to provide notifications to users."
"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."
"Network Discovery capabilities would be extremely helpful."
"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."
"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."
"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."
"If PRTG could help me see the bandwidth for each host I have on my network, either for a wireless or a wired network, that would be very helpful."
"In a very few cases, customers want more detailed reports, which we cannot meet."
"PRTG Network Monitor could improve the price."
"We have had a few issues with the web elements, as far as the dashboard. With the dashboard, it has to be manually refreshed. Occasionally, we reboot the server, or at least web services, due to the web aspect."
"When using PRTG Network Monitor it is beneficial if you have prior experience with it, the user interface could improve."
"I am not sure the solution is giving me all the needed feedback that we need."
"In the next release, PRTG Network Monitor should add a backup solution."
 

Pricing and Cost Advice

"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."
"The solution is cheap."
"The product is inexpensive compared to other DBM products."
"The solution is free to use."
"It's an open-source solution."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"This is an open-source solution with paid support."
"At the moment I'm only using 500 sensors. I pay yearly, so it's a cost that's easily swallowed."
"The pricing is okay and it is cheaper than some competing products."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"We pay for a perpetual license and we have a support fee."
"PRTG is now available as PRTG Enterprise Monitor, and the price varies depending on the total number of sensors the customer buys"
"PRTG Network Monitor's price is a little high."
"The pricing is comparable."
"We've got 1,000 nodes and I believe it's a few hundred quid a month."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
