Azure Network Watcher vs. Nagios Core

Azure Network Watcher is well-suited for cloud environment, it's necessary for the network troubleshooting. It is especially useful in where you have done integration with azure virtual wan and custom routes (udr) to control traffic in a hub & spoke network with Azure firewall. When the traffic is manipulated with udr, the troubleshooting at the routing level becomes important in some cases.

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.

• 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.

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.

Azure Network watcher provides various feature that stacks up against other products such as monitoring which include network monitoring and connection monitoring etc. Diagnostic feature which includes connection troubleshoot, VPN troubleshoot etc. Logging feature which includes network traffic analysis and helps in understanding network traffic more efficiently. All these features in azure network watcher make it worth.

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.

• 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.
