Nagios Support Forum

I want to know which OS is the preferred one for deploying Nagios XI - RHEL or CentOS? What are the reasons contributing for one OS deployment popularity against the other (eg. cost savings in case of CentOS)?

Thanks in advance.

Really, the major difference between the two is one is Enterprise based (RHEL) and the other is completely open, and does not need licensing. Many clients/customers choose RHEL because of their licensing and support options. For all intents and purposes CentOS/RHEL are virtually identical, and either would work equally as well, it's more up to what you have chosen to use in your environment. More info can be found on their respective project sites.

Thanks slansing.

I understand the OS dynamics but my question was mainly to understand it from Nagios XI install base perspective. I understand the OS deployment is very customer specific based on the customer needs/ constraints regarding licensing/ support but my question was mainly to understand Nagios XI install base. Do we have some data (quantitative or qualitative) pointing out that Nagios XI install base is higher on one OS than the other?

No we do not, they are at the same level as far as XI is concerned. It is more of a personal taste/policy issue rather than how XI / Core / Our products work with them, they should work equally as well on both distros.
