Nagios Core vs. Preseem

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.

For any ISP that wants to know the QoE their customers experience while using their service, Preseem is an excellent choice. The rate plan shaping also makes sure the connection feels fast, even if the speeds are being 100% utilized by the customer. This is not a DPI service though, so you can't classify or shape certain services over others. All traffic is treated fairly, and small flows are moved to the front of the queue to make sure interactive traffic like VOIP, DNS, and gaming is working well ahead of large downloads.

• Network and server status alerts if a device is in a down state.
• Gives you the top view down of your entire network infrastructure.
• It can be customized to your exact needs.
• You have two options of agentless and agent monitoring.

• Excellent web interface that shows all the relevant performance data
• Great customer service
• Fair pricing
• Great rate plan shaping to maintain low latency
• API integration with our billing systems and many others

• 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.

• The tool could stand to be a little less engineered, but really the ROI isn't there for them to do so. I don't think most of us care about how pretty it looks, more so does it work and can I figure it out in relatively short order.

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.

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.

Any Amplifi product can show client infrastructure usage and date. the Dream Machine is perfect because it has built-in everything for the client to manage his local network.

• 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.

• Preseem has increased our ability to service our end users without hiring additional staff.
• Well worth the cost - less frustration for network managers.
• Runs in the background with little to no input from network manager.
• Very reasonable cost to operate.
