Icinga vs. pfSense

Icinga is a world-class monitoring system. It can be used for most general monitoring situations. It is not a silver bullet, however, and there are instances where domain-specific monitoring systems are necessary. However, the output from those monitoring systems can be funneled into Icinga as a central monitoring and alerting system.

pfSense is incredibly budget friendly and capable for organizations of all sizes. My specific scenario, working for a non-profit organization, requires budget consciences decisions without compromising security and function. pfSense has helped tremendously in accomplishing this. It specifically tackles advanced routing, static routing, remote access, intrusion prevention, in a single platform, mostly available for free.

• Wealth of community-developed plugins.
• Stable codebase.
• Icinga 2 supports distributed monitoring.
• Very performant, can support tens of thousands of checks per server.

• Easy to use. Good user interface design! Easy to understand and easy to set up.
• Lower hardware requirement. 3 years ago, we used an old PC to run it. Now, we have changed to a router device with Celeron CPU and 8GB RAM. It runs smoothly with a 1000G commercial broadband.

• High learning curve, setting up Icinga from scratch can be a bit of a challenge starting out.
• If the io2db process fails you UI stops updating, which can be very frustrating.
• There is no simple mechanism for adding new hosts and services through the web UI, it's all very config-file based.

• I did kind of mention a Con in the Pro section with OpenVPN.
• When I create a config for an employee other employees are able to login to that config.
• I could be doing something wrong when I am making it - I am not afraid to admit that as I am pretty new to all of this, but it seems like it builds a key and I would think the key would be unique in some way to each employee, but I could be wrong.
• I actually do not have a lot of Con's for this software - I did not get to set this up on our work network so I am not sure of any downfalls when installing.
• I installed this on my personal machine in a Hyper-V environment to get a feel for it before I started working on it at work and it seemed pretty smooth. I didn't run into any issues.

Icinga is a solid solution which does everything it promises. It is backwards compatible with most Nagios instances, making the transition very easy. Once you get the hang of installing new plugins and editing configuration files expanding its monitoring capabilities are easy.

The pfSense UI is easy to navigate and pretty go look at. It is much better than some high dollar firewalls that just throw menus you you. The pfSense UI is quick and responsive and makes sense 99% of the time. Changes are committed quickly and the hardware rarely requires a reboot. It just runs.

Icinga is better than Nagios because of its nicer user interface. New Relic can monitor CPU/memory and disk usage, but it's more of a performance and application troubleshooting tool rather than monitoring

Meraki has a unified management login for all devices, which is nice. It also has decent content filtering, both areas where pfSense is weaker. Where pfSense far ouclasses Meraki is in the ease of use and the other width of features. These include features such as better VPN interoperability, non-subscription based pricing, auditability, not relying on the infrastructure of a third party, more transparency of what's actually going on, easier to deploy replacements if hardware fails. Additionally, the NAT management for pfSense seems to be a bit better, as you can NAT between any network segment and not just the LAN segments out the WAN interfaces.

• With one check you know which applications are faulty e.g. after an upgrade. Which is big time saver
• You easily detect outages ion the applications so that your customer ideally does not even realize there was an outage.
• Detect if the environment does deliver the same result as in the same time as before to detect shortages.
• Additional information when debugging. Saved us several hours where we could simply point to a database which was slow.

• pfSense can be installed on commodity hardware with no licensing fees. With a simple less than 10 minute restore time, on most hardware, it's an extremely inexpensive way to achieve the same results that some of the more expensive vendors provide.
• The easy to use interface has allowed configuration management to be preformed by lower level technicians with quick and easy training.
