"We can manage the entire system across the network and troubleshoot the pain points."
"The most valuable feature of Nagios Core is the ability to check the availability of the server for network connectivity. Additionally, the interface is good."
"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 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."
"Our customers like that Nagios Core is an open source solution. It can be customized to our customers' specific needs."
"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."
"Key features include the GUI interface, its notification capabilities, and the real-time reporting."
"The application performance monitoring feature is valuable."
"We mostly use Nagios Core to integrate with Python and Bash Script."
"The sensors and remote probes are phenomenal. We use them for all of our global sites. The problem with our global sites are that they are all VPNs. If the link goes down, you can't monitor other solutions, as it just goes off the grid. Having remote probes allows them to still carry on and get the information that we need when it comes back up, sending the information to us."
"The email notifications are helpful, and the dashboards are user-friendly for people with little network monitoring knowledge."
"It gives me a live view of the traffic on the WAN."
"The solution provides us response times to issues."
"We can see which fiber links have been used heavily and, if they are used heavily, we can introduce more links to particular buildings or particular areas."
"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."
"The fact that I can use custom MIB files to customize my sensors for the things that are not there as a default is a good feature."
"The installation is not that complex."
"The Wi-Fi side needs improvement."
"Nagios Core can improve the graphical interface, it would make things a little easier."
"The dashboard and monitoring features could be improved."
"Making it a little easier to configure and set up from the start would help. There are multiple layers that you have to wade through to be able to set it up, to do it the right way, and to get it to do what you want it to do."
"Would benefit from aggregations if a particular server goes down."
"Cloud monitoring is an area for improvement because there aren't too many plugins available."
"The core version is no match for the XI version."
"Nagios Core is limited in terms of distributed setups, and there is no central view for remote data centers."
"The UI is a little outdated and graphics could be displayed in a better way."
"PRTG's documentation could be improved."
"The dashboarding definitely needs improvement."
"The icons on PRTG's network diagram are hard to find. For example, finding the icons for firewalls and servers is difficult, so we're struggling to create the network topology."
"Needs ability to monitor standard notification time (notify after X time)."
"The thing that we do struggle with a bit is in the historic data. If I want look over 30 days, because it averages out onto one graph, you can't zoom in and drill down information."
"There seems to be a big jump from the basic scan to the really thorough scan. There is a big jump in the quantity of sensors it uses for certain things. One minute you might get ten and then the next you get 200. There seems to be a big jump between the two at times."
"We would like to monitor certain aspects of the user experience. We should be able to analyze the cause of end user experience, bad or good, so we can do some research and development on our own."
"The technical support service should be improved."
