Featured Reviews

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.
Noman-Saleem - PeerSpot reviewer
Detects suden changes but significant pricing concerns affect the effectiveness of network traffic troubleshooting
We use PRTG Network Monitor for monitoring traffic on interfaces and the behavior of network traffic. If there are sudden changes in traffic or any configuration issues, we can sort them out using PRTG. It's very helpful for troubleshooting and monitoring traffic utilization on our interfaces…

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The value of Icinga is that it has hundreds of plugins, so it's really easy to monitor pretty much anything."
"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."
"Icinga does the job and is fairly stable."
"An affordable solution for small organizations to do basic network monitoring."
"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."
"It is really easy in Icinga to create your own plugin and integrate it without any fuss. And it works just perfectly fine."
"The remote probe feature in PRTG Network Monitor helps you monitor remote systems or your network at a lower cost than other solutions."
"PRTG Network Monitor's best features are its flexibility, ease of implementation, user-friendliness, and intuitive interfaces."
"The most valuable feature of this solution is being able to see things graphically."
"The most valuable feature is the ability to span multiple technologies and multiple vendors."
"The initial setup was easy. We didn't have any issues with the process and everything rolled out smoothly."
"Ability to create a dashboard inside software monitoring."
"Ease of set-up – it is quick and easy to add a probe and start collecting data from a device."
"Every monitoring session features similar capabilities."
 

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."
"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."
"There is room for improvement in multi-tenancy. It's not perfect, not even really good. It's average, but it should be improved."
"The user interface should be improved."
"One of the areas that are frustrating is remote monitoring for more than one machine."
"Icinga’s automation could be improved."
"One thing that Icinga lacks is the capability to create advanced and customized dashboards within the tool itself."
"PRTG Network Monitor can improve the reports. In the reports, you have to give an alert for that SMS and email, the emergency calls and downtimes have to be reported accordingly. You have to enable email services or an SMS gateway service to receive more alerts at the proper time."
"The clustering aspect needs improvement, as there is a bit of confusion about you do when hit that 5000 probe mark."
"More training videos for installing and configuring this software would have been nice, especially when working with a lot of devices."
"We need something that is more predictive. We would prefer if it wasn't a solution that was corrective and instead offered predictive insights so that we can handle problems before they even occur."
"The Desktop app is good but it can be really sluggish at times, especially when you're editing different elements."
"We've had some issues previously with the performance of the sensors. We tend to deploy quite a bit of WMI, which is quite processor-intensive, and we've found that that impacts the sensors quite a bit."
"Needs ability to monitor standard notification time (notify after X time)."
"Users need to buy the more expensive licenses if they expect to be able to scale."
 

Pricing and Cost Advice

"It is cost-effective, and the return on investment can be very interesting because the price is low."
"The solution is free to use."
"This is an open-source solution with paid support."
"We're using the free version of Icinga."
"It's an open-source solution."
"Even though Icinga's financial cost is low, it is an expensive product regarding the resources required to maintain and operate it."
"The solution is cheap."
"The product is inexpensive compared to other DBM products."
"We pay for PRTG Network Monitor annually. The price is approximately 10,000 rupees annually."
"There is a license to use PRTG Network Monitor and it is annually."
"Our licensing costs are 10,000 euros over three years."
"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."
"I'm paying something like €1000 per year for the maintenance. I've got unlimited sensors."
"It is expensive."
"PRTG Network Monitor is cheap."
"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."
