[op5-users] Some questions about Merlin

[Jelle Smet]

Hi List,

My primary concern is to off load active checks from my centralized system to a proxy to reduce load on my main server.
I'm not (currently) interested in using another web front end for my Nagios setup.

Looking at following example included in the README it looks like the setup I require:

On nagios1 (the "master" server), add the following section:
  --------------
  poller nagios2 {
    address = 192.168.1.2
        port = 15551
        hostgroup = germany-hosts; # name of the hostgroup containing all
                                   # the hosts you want this poller to check
  }
  --------------

On nagios2 (the slave server), add the following section:
  --------------
  noc nagios1 {
    address = 192.168.1.1
        port = 15551
  }
  --------------


* Do I need to install mysql on both Master and Slave server?
* Can I just define my host & service definitions as usual on the Master using default nagios file based config without ever having to touch the Slave (given that the commands are defined correctly on Slave I presume)?
* Are all service & hosts checks that are defined on the Master in the germany-hosts group automatically switched to passive services on Master?
* Are the hosts & service checks for germany-hosts actively executed on Slave and inserted as Passive results in Master?
  * If so, does it have the same performance benefits as relying on the classic passive checks?

Sorry for possibly obvious questions, but after reading the documentation I still have these questions..

Thanks in advance

Jelle Smet.
