Easy to use and deploy with helpful technical supportThe pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more. An optional delivery from their end in order to greatly produce some sort of a HA, high availability solution, would be ideal. At present, if I have a solution and Nagios is instanced in a particular data center and another Nagios solution in another data center, when you buy the license, you can eventually have different types of licenses. One will be a stand-by and the other will be a disaster recovery solution. What's missing from the Nagios side is the idea of having some sort of synchronization between the two instances. If I have a stand-by solution and I need ticketing as an active solution, I need to do many things manually. For example, I need to manually do ticketing on the backup and restore it on the other. It would be a good idea for some sort of mechanism, like a sort of clustering, which can help a lot for people out there who need something in an active-standby solution. I'm not sure this will be available out there even on other solutions, like Zabbix, for example, That said, I don't think they're really digging into this kind of scenario. When you start deploying thousands of monitors, especially in a big company, for example, you have to take care, as that you cannot keep on pushing into one solution. It can become inefficient. They say it's specifically that when you skip an X amount of monitors, Nagios starts behaving differently. I really don't like the idea of the certification provided by them. As a company and as a team lead, I have other people who were interested in doing some certifications, coming from the management. However, they did not provide any sort of training, which gives you the independence to do an exam. It's like they just provide a simple document for you to read and then just to apply in the exam, just to be Nagios certified. On top of that, that kind of document is very old. I asked them if they had anything up-to-date. They told me that's what they have even though it's clear it's very old quality for the current engine that Nagios is currently built on. There were quite a number of upgrades - at least five. At the same time, Zabbix certification offers you training beforehand and then you can opt for either a certification or an exam.
