Network Performance Monitoring
Comparison of Network Performance Monitoring features of Product A and Product B
Nagios is simply a very configurable and rock solid monitoring engine. For these reasons I would recommend it to any IT professional in any medium to large organization where creating custom checks and programming ones custom needs into the configuration is practical. I would be more hesitant to recommend it as a first monitoring solution for a small business which is usually accompanied by a less experienced and/or more time constrained admin.
Nmap is the ideal solution if you are working alot in network environments. If you come to grips with the syntax and the most-used features (the online community helps alot), you will be able to much more quickly and thoroughly troubleshoot networks or check for security vulnerabilities, for instance. It is free to use and is available for Windows and Linux, so I would say it is very much warrented for any network administrator or sysadmin to take it out for a spin.
It's built by engineers for engineers so setting it up and configuring it is relatively complicated. It could really use a simplified configuration approach, or a GUI to set it up instead of editing config files.
I'd like to see the option to have service notification settings inherited from the host setting notifications. They have to be set up separately but they are often the same, so it would be nice to have less redundancy.
exporting, There's a serious lack of ability to export the information in a readable format to present to VPs and such. I always find myself doing a lot of data massaging to get it in a pretty format
some scans can trigger sensitive IDS/IPS
SYN scans can be particularly aggressive and cause problems on remote systems.
We're currently looking to combine a bunch of our network montioring solutions into a single platform. Running multiple unique solutions for monitoring, data collection, compliance reporting etc has become a lot to manage.
The Nagios UI is in need of a complete overhaul. Nice graphics and trendy fonts are easy on the eyes, but the menu system is dated, the lack of built in graphing support is confusing, and the learning curve for a new user is too steep.
Nmap uses are very practical and I don't think there is a better tools for what Nmap does. It is open-sources that therefore there is no cost to use it. It offers a number of benefits, including but not limited to network mapping, port scanning and more. It is very reliable as a network scanning tool.
I haven't had to use support very often, but when I have, it has been effective in helping to accomplish our goals. Since Nagios has been very popular for a long time, there is also a very large user base from which to learn from and help you get your questions answered.
There is a very large support community and a robust selection of add-ons and scripts. Once you get the use down this is one of the most powerful tools and you can find anything you are looking for as far as examples on the web. While not having official support its not lacking by any means.
We have tested several other monitoring products which were able to monitor the basic matrix (Memory, DiskUsage, CPU%, UpTime, Running Service Status, Port 80 Up/Down). Although some offered far better UIs, they lacked the ability to monitor ANYTHING. Zabbix, being the only contender worthy of competing, is a good alternative to Nagios. We also tried Zenoss Core & OpenNMS which were good enough for non-Linux engineers to get started with. OP5 was another service-oriented monitoring solution we evaluated. Apart from Nagios, Consul is heavily used to monitor & register the micro-service systems & end-point URLs. Due to the time invested (9+years) in Nagios, we were able to get more components installed/configured easily than alternatives.
A similar but more basic alternative is available on Android, called Fing. It's very useful for diagnosing issues on networks when you only have your mobile device to hand.
A graphical user interface alternative to Nmap, is Zenmap. It's the official GUI for Nmap and does use Nmap under the hood. It makes things a bit more 'point and click'.
With it being a free tool, there is no cost associated with it, so it's very valuable to an organization to get something that is so great and widely used for free.
You can set up as many alerts as you want without incurring any fees.
NMap being free of charge has a positive impact on our budget. It is an enterprise-class tool that anyone can download and use.
NMap, both command line and GUI, is a very advanced tool that is easy to use, so there's very little learning curve involved, which has a positive impact on productivity and security.
A valuable feature that is a huge time saver is that you can compare scans. This saves hours of searching manually for differences in scan results. Faster results means faster mitigation of problems, which can be a real money saver.
