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

"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"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."
"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."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"There's a module called Icinga Director, which helps us configure the product using an intuitive interface through clicks instead of creating a text configuration. It's very helpful for us."
"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"Stability-wise, I rate the solution a ten out of ten."
"The network visualization helps us to drill down deeper."
"PRTG is relatively intuitive and fairly straightforward. It has net flow monitoring and that works all right. I would describe it as a decent middle-of-the-road solution."
"It is a very stable solution. There are no bugs, glitches and we have not experienced any crashing."
"The initial setup is very simple."
"The real-time monitoring feature in PRTG is invaluable to me"
"PRTG Network Monitor is easy to set up. Within a few minutes, it is operational."
"This solution provides us with the needed feedback on our IT infrastructure. It allows us to grab all the information from a single point of view."
 

Cons

"One of the areas that are frustrating is remote monitoring for more than one machine."
"The tool currently fails to provide notifications to users."
"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."
"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."
"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."
"The installation and configuration are very complex."
"We have found some problems with Nagios, and support isn't very responsive."
"The user interface should be improved."
"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."
"Mostly, this software has sensors for devices to monitor specs and you can build or develop or modify various sensors, according to your company's needs. But you may need to do that with coding or plugins or with the support of Paessler AG, the manufacturer."
"I would like to see network mapping."
"They should work on syncing the solution with Gmail."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
"Sometimes, it is difficult to drill down further to get information, e.g., if we saw spike in traffic, then we would want to drill down and find out what is causing that spike in traffic."
"Technical support is an area with concerns in PRTG Network Monitor, where improvements are required."
"The operations dashboard is only available in PRTG's enterprise version, but I wish it could be accessed in the standard licensing. It would also be nice if PRTG had templates for dashboard monitoring, software monitoring, etc. It can help me set up a dashboard because now we don't have a template from PRTG, so we need to create one from scratch."
 

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."
"This is an open-source solution with paid support."
"It's an open-source solution."
"It is cost-effective, and the return on investment can be very interesting because the price is low."
"We're using the free version of Icinga."
"The product is inexpensive compared to other DBM products."
"The solution is free to use."
"The solution is cheap."
"When you have a lot of devices, PRTG Network Monitor can be costly."

"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"Sensors on free version can run out quick."
"We pay nothing for it. Its 100 sensors have allowed us to put a magnifying glass on some systems, providing an extra layer of detail. Therefore, our outgoing is nothing and our incoming is a lot of useful data that we can react to proactively."
"We are licensed for 2500 endpoints."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"PRTG Network Monitor's price is a little high."
