SolarWinds AppOptics (formerly Librato) is an IT infrastructure monitoring service and APM, based on technology acquired by SolarWinds with Librato in 2015 to expand its cloud monitoring portfolio.
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.
AppOptics is good for small to medium-sized organizations with less than 150 servers or less than 40 services to monitor. It performs well for this use case where people need to get an overview of application performance, and 95%ile data is okay. Somewhere every data point and every record is critical; it should be avoided.
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 only thing that I would add is the possibility to display every single query our servers receive to eventually analyze them and query through them. We could also generate nice visualizations from that. Right now I believe we can only see averages.
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 a usability is concerned for AppOptics, it is just as matter of few minutes away even if you start from scratch, as all you need to do is register on the site and you will get the URL and password. And after this all you have to do is follow the instruction, as per the configuration wizard (tool tip) within the console for various technology such as SQL, IIS, .NET
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.
Solarwinds AppOptics is rated as 9 out of 10 and the reason is there are still few areas where AppOptics needs to improve such as Service Now Integration, GCP Cloud Support, Better Dashboard visualization for application transactions flow. Other than these feature everything is there in AppOptics and that's a reason given 9 points out of 10.
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].
What we found positive in AppOptics from others is:
Easy to install and manage.
Various stack support.
Point to point deep-dive metrics and correlation.
Metrics like DB connection, query analysis, latency in API calls, and other connections, response codes for various APIs, etc are the key ones in our case, which AppOptics provides efficiently.
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.
