Pros
"We can manage the entire system across the network and troubleshoot the pain points."

More Juniper Mist Premium Analytics Pros →

"What I like about Nagios Core is that it helps me ensure everything is running smoothly by checking the status of hosts and services.""The most valuable feature of Nagios Core is it allows us to develop and add as many plugins as we want.""Dashboard provides monitor of total assets.""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.""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.""The most valuable features are the reports and the way it generates the report in a graphical manner.""We mostly use Nagios Core to integrate with Python and Bash Script.""The application performance monitoring feature is valuable."

More Nagios Core Pros →

"Good compilation of the system's information.""It improves the status of my infrastructure, from networking devices to real-time machines.""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.""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.""I really love the activity library. It gives the flexibility to discover data and metrics about my interface and data server.""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.""The network visualization helps us to drill down deeper.""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."

More PRTG Network Monitor Pros →

Cons
"The Wi-Fi side needs improvement."

More Juniper Mist Premium Analytics Cons →

"The tool needs to improve the integrations.""The scalability needs improvement, it's not scalable at this time.""The initial setup process could be easier.""It is a bit slow due to latency.""I would like to see a sensor that shows the traffic of a user and what they're doing on the network.""The UI is a little outdated and graphics could be displayed in a better way.""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."

More Nagios Core Cons →

"Integration into service management ticketing systems could be better. They should simplify the integration into big service management platforms like ServiceNow, Remedy, and Cherwell. They're really into monitoring, but they don't do any self-resolution. It would be better if the company moved more into the AIOps space so that you could actually kick off some remedies. I know that you can execute some commands from the tool, but you need to develop those all yourself. It would be really handy if they had some auto-remedy scripts that they could develop on top.""PRTG would be improved if it required less memory to run.""The product could be improved by being cross-platform friendly.""They just released a newer version of the desktop app, a beta version, that I have been trialing out. I prefer the older version, only because of how the layout is designed""I am not sure the solution is giving me all the needed feedback that we need. When something goes off on our IT infrastructure, it does tell me. However, it would be nice if it gave more intuitive information, e.g., the hard drive has gone up by 60 percent in an hour.""I have an issue with DFS, distributed file services... there isn't one by default. Taking into account the difference between DFS and DFSR as well would be great.""PRTG Network Monitor can improve by having better integration with devices.""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."

    I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want using these, but they require quite some expertise before you can use them. Then there are the ones that are not open source, the enterprise softwares and cost you some money, but on the other hand, they are extremely easy to set-up and learn. You can have them up and running in a matter of minutes. And then there are those which are completely cloud based. They can be free of cost or charge some money depending on the software. The good thing about these is that you don’t have to install any extra software, and it can be managed completely online but then again these have limited features and you cannot exploit them to the full extent as you can do with the open-source and to some extent the enterprise software, so I won’t suggest you to use these, because these are generally not the complete solutions and require other support software to achieve the same. Below I have listed the outstanding pros and cons of the various Network analyzers that you can look into Nagios Pros: Nagios offers an extensive set of collector plug-ins that allows users to gather performance and availability data from a broad range of operating systems, including  Windows and Netware Nagios… Read more →
