My name is Eduardo and this is the first post in nagios forums. I’m starting to deploy a new nagios+centreon distributed monitoring platform because the previous one was installed with no documentation and it’s working very bad.
I’m going to monitor a lot of hosts and services, so I’m starting with 2 servers. One as master (but it will monitor some services and hosts) and other as slave with a lot of virtual machines monitored. I’ll monitor switches, windows 2003, windows 2008 R2 (64 bits), webpages, 32bits linux distros and 64 bits linux distros.
My first question is about the master and slave OS: I’m going to use CentOS 5.5 (it’s “our” Linux distro). My question is ¿32 or 64 bits? My nagios servers are not going to use more than 4GB of RAM, so I think this is not a reason to use 64 bits, but I’m going to monitor 64 bits servers (linux and windows)
¿Any suggestion / idea / best practice?
Thanks in advance everyone
