SolarWinds Netflow Traffic Analyzer is a network monitoring tool within the broader SolarWinds ecosystem. It includes core traffic monitoring features, as well as customizable traffic reports and alerts.
We used Nagios previously and also the Nagios Netflow Analyzer. It did a good job, but SolarWinds Network Traffic Analyzer is far superior and far more feature-rich in terms what you get. The planning it provides and alerting easily outweighs what Nagios Netflow can give. It is …
Nagios monitoring is well suited for any mission critical application that requires per/second (or minute) monitoring. This would probably include even a shuttle launch. As Nagios was built around Linux, most (85%) plugins are Linux based, therefore its more suitable for a Linux environment.
As Nagios (and dependent components) requires complex configurations & compilations, an experienced Linux engineer would be needed to install all relevant components.
Any company that has hundreds (or thousands) of servers & services to monitor would require a stable monitoring solution like Nagios. I have seen Nagios used in extremely mediocre ways, but the core power lies when its fully configured with all remaining open-source components (i.e. MySQL, Grafana, NRDP etc). Nagios in the hands of an experienced Linux engineer can transform the organizations monitoring by taking preventative measures before a disaster strikes.
We use and depend on it for status state of our network gear, switches and routers. It does an excellent job of getting you the details you need to confirm all devices and products are working at the level needed. At times, it does tend to flag network switch ports and/or switches themselves as exceeding their rated capacity when frequently it was a quick blip of high traffic due to downloads, or uploads causing the max'ing of the device. Again, you can adjust the settings but then you adjust it too high and miss real activity. It can become nuisance alerting when you tend to then ignore
The level of customization possible with Network Bandwidth Analyzer is very valuable. Rather than being stuck with a "one-size-fits-all" presentation, an administrator can easily create customized views, reports, and alerts so that users can have a more tailored view of the data provided by Network Bandwidth Analyzer. This has the effect of making the tool more attractive to the end user.
The NetFlow Traffic Analyzer piece of Network Bandwidth Analyzer provides the details on bandwidth usage on the network. More than knowing how much bandwidth is being used, one is provided with detailed information on how that bandwidth is being used. This provides invaluable information for capacity planning and even certain forensic tasks faced by the network engineer.
The ability to produce network maps provides an easy way to create an attractive and functional NOC/SOC view of the entire network. Both technician and the occasional passerby can quickly determine if there are issues to be addressed. The ability to customize a map with background images and custom icons and stencils can make these maps really pop.
Nagios could use core improvements in HA, though, Nagios itself recommends monitoring itself with just another Nagios installation, which has worked fine for us. Given its stability, and this work-around, a minor need.
Nagios could also use improvements, feature wise, to the web gui. There is a lot in Nagios XI which I felt were almost excluded intentionally from the core project. Given the core functionality, a minor need. We have moved admin facing alerts to appear as though they originate from a different service to make interacting with alerts more practical.
The ability to intuitively and quickly serve up specified information up to a dashboard for general “public” consumption, that cycles through several pages of information.
The ability to intuitively set up alerting on bandwidth levels, instead of having to dig through all types of alerts available to find the one needed.
Provide a pricing model based on different support levels: if I want only available update installations, don’t make me pay the same amount as those wanting full support.
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.
As far as rating for usability is concerned I would give 10/10 as NTA is very easy to use. All you need to do is install that module and ask network Team to configure the Netflow towards Server IP. [The] rest is pre-configured and reports are pre-built. Moment you receive the flows from Network all you will have is information about traffic.
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.
I know we could probably pay for it, but it would be nice if we could get to a tier 2 technician faster. Spending a couple of hours on the phone with the level 1 technician, when we have already tried the troubleshooting they are walking us through, is just a waste of time.
The training offered by SolarWinds is some of the best out there. They have several different videos that go into great detail from initial setup to advanced configurations. In addition to the view at your own pace video, they also have live training for customers that focus on a single product and you can ask questions with the folks who develop the software. I have had good success with their live sessions and getting questions answered.
Because we get all we required in Nagios [Core] and for npm, we have to do lots of configuration as it is not as easy as Comair to Nagios [Core]. On npm UI, there is lots of data, so we are not able to track exact data for analysis, which is why we use Nagios [Core].
SolarWinds NetFlow Traffic Analyzer compared to Wireshark and PRTG Network Monitor beats it by just the simple interface. Though all are manual setup, NTA takes it a step further with graphs and reports that analyze the data for you. In comparing to Extrahop from a bandwidth comparison, Extrahop wins but Extrahop is a lot more than just a bandwidth monitoring and cost.
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.
Be prepared to answer lots of questions. When people see the data in NTA they are going to want to know why App A is talking to App B. Be ready to explain!
Hand the keys to the NTA kingdom to the network team. They will thank you. Everyone wants to have friends on the network team, right?
Be prepared to invest in some significant compute and storage performance to keep up with your NTA monitoring
Running the latest firmware for your network gear is (often) required to take advantage of all the flow-monitoring. You upgrade regularly, right??
