Room for Improvement: Nagios Core users have requested better documentation, improved scalability, and a more user-friendly configuration process. PRTG Network Monitor could improve its performance and resource efficiency. Other pain points include usability and cross-platform compatibility.
Service and Support: Nagios Core lacks direct customer service, but users can generally find help from a supportive open-source community and large knowledge base. PRTG Network Monitor received mixed reviews for its customer service. Some users commended the support team’s prompt service, while others reported slow response times and noted the lack of remote session support.
Ease of Deployment: Nagios Core's setup is generally seen as well-documented and straightforward. PRTG Network Monitor’s setup isn’t considered to be overly complex. Deployment times may vary depending on the environment's complexity and device count.
Pricing: Nagios Core is free, but users may incur costs for installation and configuration. PRTG Network Monitor is deemed reasonably priced and cheaper than its competitors.
ROI: Nagios Core users say they have saved money by replacing paid monitoring tools with this open-source solution. Users said that PRTG Network Monitor has proven to save time and money through automation and proactive support.
Comparison Results: Nagios Core is a flexible open-source solution that is highly customizable and offers robust functionality commonly found in paid enterprise solutions. However, some users have said that Nagios Core becomes unwieldy when used at a large scale and that the documentation could be more thorough. PRTG Network Monitor is regarded as a simple, user-friendly, and cost-effective solution, but users would like to see improvements in performance, documentation, integration, and technical support.
"We can manage the entire system across the network and troubleshoot the pain points."
"Nagios monitors our servers, so we know if anything goes wrong and can solve the problem before it happens."
"The most valuable feature is the performance parameters of the system."
"I like the way the solution sends alerts and how it keeps on escalating them."
"Dashboard provides monitor of total assets."
"The notifications are definitely one of the most valuable features of Nagios Core. We know what to look for and what to expect when things are down."
"Other products are good but from the configuration point of view Nagios is really very lightweight. The price is really good in my opinion. Another important thing is that my Nagios engine still works with Dual core 8GB ram for the last 10 years."
"Alert calls occur anytime a service goes down or a matrix is difficult and that helps us to quickly restore service and transfer work."
"The solution is quite efficient."
"The solution is very easy to use and the web provides information with ease."
"The most valuable feature is the ability to span multiple technologies and multiple vendors."
"The scalability is good. You can improve a remote host or the clustering. This gives it the flexibility to monitor another infrastructure remotely."
"The remote probes are very useful. They allow us to provide a reference across different areas in the network. In trying to localize issues, that's very useful."
"It improves the status of my infrastructure, from networking devices to real-time machines."
"I found PRTG Network Monitor very useful for troubleshooting and monitoring the utilization of either the network or server."
"The most valuable feature is the notifications. As long as you spend time and think about what and when you want to be notified, it's always accurate. It is always there. I find things out before my Internet provider."
"I would boldly say that this is the most scalable network monitoring tool that I know of"
"The Wi-Fi side needs improvement."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The scalability needs improvement, it's not scalable at this time."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"Would benefit from aggregations if a particular server goes down."
"The user interface could be more interactive because it is pretty basic."
"It's not that easy to install the product itself. Also, the UI is a bit hard for regular users to navigate through."
"The initial setup process could be easier."
"The core version is no match for the XI version."
"Users need to buy the more expensive licenses if they expect to be able to scale."
"There's always room for improvement. The high availability feature is good, but it's an area that PRTG could marginally improve. For example, in PRTG, both servers have a different IP, but it would make things a lot easier if they were bound by a single IP."
"A room for improvement in PRTG Network Monitor is its sensors. Its application technology sensor, such as the IAS, .NET, etc., needs some improvement because it doesn't work as expected. For example, the IAS sensor doesn't give immediate information, and the information you get from it isn't of good value. The web GUI of PRTG Network Monitor also needs improvement because errors keep popping up if it's not been updated to the latest version. What I'd like to see in the next release of the tool is end-to-end topology mapping for the business model, and that should be required. There has to be a technical map. Technical mapping and topological creation are missing in PRTG Network Monitor, so I would like to see those in the future."
"I would like to see more updates available in this solution."
"While the desktop app is good, they could slightly improve it. We would like it to be a single pane of glass. At the moment, you can only see certain portions of information. You have to scroll through to make it more granular. We want them to develop the desktop app to be more user-friendly."
"In a very few cases, customers want more detailed reports, which we cannot meet."
"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."
