PathSolution’s TotalView is a network performance monitoring tool. PathSolutions emphasizes the platform’s issue diagnostics and recommended remediation assistance as a key differentiator.
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.
TotalView is well suited for an infrastructure where you are looking for a cost-effective, additive network management tool for in-depth device diagnostic information. This will not be a one-stop shop application, but it does what is advertised very well. SNMP is required for configuration and adding additional devices is quick and simple. This product also works well with Shoretel VoIP systems and allows for a full overview of connected phones along with being able to view calls on an extension/IP basis.
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.
If you have some complexities in your network addressing, the network diagram tool will lay everything out automatically, but it will be confusing to look at. There is a way to edit the diagram so it looks more intuitive, but it may require some time to edit everything the right way.
TotalView will count virtual interfaces such as voice dial-peers and service modules as "ports," which counts against your license count. However, there is a way to edit each device to remove these "false positives" so it doesn't suck up licenses, but it can take some time to clean those up.
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.
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.
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].
The three tools listed do different things with some similarities. For us the biggest need was data analysis, semi-automatic troubleshooting, and data gathering and topology mapping. TotalView hit the most of these in the price point we were looking for. Each tool has "extras," but we felt that the extras provided by TotalView were good enough and that the other tools didn't justify the 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.
