General Core to XI questions
General Core to XI questions
We currently have a Nagios Core 4.0.7 installation running on RHEL 6 64bit montioring around 330 Linux hosts and about 1700 services. We purchased a Nagios XI enterprise license and are planning to build a new beefy RHEL 6 VM and spin up XI to replace our current Core installation. In addition we will be adding monitoring for around 300 Windows hosts and 50 AIX hosts to the new XI server. I was considering installing the database on a separate VM for performance reasons. I assume this would require and install from source with customizations for database creation/connection info? Are there multiple databases for Config and for Historical Metrics? Are there best practices for moving forward with the configuration I describe above? I don't know a lot about the differences in the inner workings of Core vs XI. I have seen some posts about Static config files vs non-static(database I presume) config files and I have heard there are tools available to "import" Core configs to XI, but I'm not sure this is the best way to move forward. If the best long term solution is to build XI from scratch then I am OK with that, just looking for guidance before jumping in.

1.) MySQL can be offloaded quite easily, and the remote DB really can be yum installed, no need to compile: http://assets.nagios.com/downloads/nagi ... Server.pdf
2.) Importing the configs from Core is also pretty straight-forward and is the way to go if you are switching to XI: http://assets.nagios.com/downloads/nagi ... ios-XI.pdf
3.) All the configs from the Core Config Manager are stored in the MySQL db "nagiosql" and historical data (for reports) is stored in "nagios". Performance data is stored in RRD files, not a MySQL db.
4.) Static configs are stored in .../nagios/etc/static/ and are not able to be modified in the XI web interface. It is still picked up by Core however, and the directory is useful in case you have automated tools that build configs and you don't want to mess around with the nagiosql db.

Thanks for that and the links. I was referring to the Nagios XI server "install from source" rather than using the VMware Image. Is there an advantage to using one over the other? Does the VMware image restrict certain customizations for instance?
Re: General Core to XI questions
Everything in my last post applies to the VMWare image as well as a source install. Honestly the differences are insignificant, the VM image is just faster to deploy.
