Harrison Bulley - PeerSpot reviewer
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

"This solution has a self-healing handler where if the service is down, it is automatically restarted."
"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 drafts are easy but what I like about Icinga is that there are many add-ons that you can download."
"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."
"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."
"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"Icinga does the job and is fairly stable."
"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 was only one feature I liked about PRTG Network Monitor a lot, and that was bandwidth monitoring, though, in the newer versions of the tool, that feature is now a bit lacking. Pricing for PRTG Network Monitor is also not as expensive. It's a good tool, even for beginners."
"Speed of deployment is one of the most valuable features."
"It is pretty simple to use, which is always a good thing. It's been very reliable in updating us if any issues crop up."
"It is user-friendly. It is easy to set up health checks within PRTG and use scans. It is like a self-service tool, and anyone can configure their own settings within PRTG."
"The authentication links into our standard Active Directory authentication, which is very good."
"The most valuable feature is the dashboard interface. It's very clean, it's very simple to use."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"Stable and scalable network monitoring tool. Installation is simple and straightforward."
 

Cons

"The solution lacks many features important to higher-level IT management and network support."
"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 tool currently fails to provide notifications to users."
"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."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"We have found some problems with Nagios, and support isn't very responsive."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"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."
"They could improve the process of updating the license."
"I would like to see Office 365 monitoring. Essentially, it doesn't do it. I assumed not at all, but apparently it does it slightly. However, due to issues with APIs, they currently don't provide full monitoring for O365."
"I would like to see more updates available in this solution."
"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."
"In the next release, PRTG Network Monitor should add a backup solution."
"The scalability of this solution could improve as well as the automated provisioning of the infrastructure."
"I would like to see them take their graphing tools and convert them into a collector so that we can point telemetry to them"
"PRTG Network Monitor can be improved as there is a lot of manual cleanup needed, which could be reduced."
 

Pricing and Cost Advice

"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."
"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."
"This is an open-source solution with paid support."
"We have an unlimited perpetual license, so we just pay support costs and it can scale throughout the organization."
"I would like better pricing models for smaller businesses. The free version is fantastic, but it's too restrictive. If they could just get up to 200 sensors for a reasonable fee for on-premise, I would give PRTG my credit card right now."
"The pricing is very low compared to other solutions."
"The price was pretty good, very competitive."
"The pricing is reasonable for the features provided."
"We have unlimited devices and sensors, and it is a bit pricey, but we do have unlimited sensors. With all things considered the price is fine, related to the solution itself. PRTG Network Monitor is good value for money."
"The pricing is okay and it is cheaper than some competing products."
"While I am not the person who deals with pricing, I would say that we pay around 1000 pounds a year."
