Harrison Bulley - PeerSpot reviewer
Senior Infrastructure Engineer at Net Consulting
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

"Macros and the ability to connect it to Google Maps are valuable features."
"People should know that it is simple and advanced."
"The drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"The apply rules feature saves a lot of time."
"We monitor all, starting from UPS to international mail chains."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"We have found the solution to be stable."
"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 product is simple and easy to implement."
"The initial setup is pretty easy."
"The best feature is that it lets me know what is going on. I need to know if something has gone down, I need to know if something is running very slowly. PRTG tells me that."
"It's very easy to manage when you've got time to do some work on it: things like adding devices, adding groups, adding sensor clusters, and being able to clone and move stuff around."
"I would recommend this solution because it's great for monitoring network traffic and producing reports."
"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."
"Stability-wise, I rate the solution a ten out of ten."
"I would boldly say that this is the most scalable network monitoring tool that I know of"
 

Cons

"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."
"We have found some problems with Nagios, and support isn't very responsive."
"Icinga’s automation could be improved."
"Sometimes, it is very hard to keep an overview of what's happening."
"The solution lacks many features important to higher-level IT management and network support."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"Scalability is problematic. If you have a stable environment it's good, but if the environment is growing, I had some problems with Icinga."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"PRTG would be improved if it required less memory to run."
"I posed this question to PRTG and they were unresponsive, so it seems like not enough customers are complaining about it or would be potentially using it."
"The technical support needs some improvement. The response time is slow, we normally get a response the next business day for urgent issues which is long time."
"The only sort of limitation is the actual probes. So, if you don't have enough probes on there, you can over flip them and cause the WMI sensors and SNMP sensors to sort of overload. Sometimes, they might timeout for a minute, but they do come back."
"PRTG Network Monitor could improve by having a feature to allow uploading of preset standard network switch configurations and the ability to monitor the SLA configuration, such as uptime for the switches or internet connectivity. This would be very useful."
"PRTG Network Monitor should provide syslog monitoring since it is not available at this time. There are very limited features as compared to other solutions."
"PRTG Network Monitor can improve the reports."
"There is not much not to love in this software but one item on my wishlist that has yet to be addressed in an intuitive way is the ability to use and manage templates."
 

Pricing and Cost Advice

"This is an open-source solution with paid support."
"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."
"It's an open-source solution."
"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 price of PRTG Network Monitor is reasonable for the features that the solution provides. They charge you per monitoring, not per node, it is per port that you need for a device."
"We've got 1,000 nodes and I believe it's a few hundred quid a month."
"The price of PRTG Network Monitor is more expensive than other solutions, such as OP Network Manager."
"The pricing is very low compared to other solutions."
"It is expensive."
"The pricing is comparable."
"One thing I like is that when you buy sensors, it's a perpetual license, so once you buy 2,000 sensors, you've got 2,000 sensors; it's not a recurring cost."
"I rate the price of PRTG Network Monitor an eight on a scale of one to ten, where one is a high price, and ten is a low price."
