Nagios Master/Slaves Solution...

[Chris Haulmark]

Hello,

 

Have anyone got any Nagios Master/Slaves solutions that are currently
being used in production?

 

The reason that I am asking is because I would like to use Nagios to
monitor several hosts/services at

multiple locations.  I have at least 4 facilities that I would like to
assign a Slave per facility while the

Master would stay at the office.

 

Each Slave would be monitoring the hosts and services only within the
facility that it has been assigned.

Firewalls and routings will be in place to prevent the Slaves from
interacting with each other.  Only

the Master will be accessible from each of those Slaves.

 

I have experimented with using NSCA to send passive checks over to the
Master from each of the Slaves.

It seems to be the solution only if I am not concerned about the Master
having a failure or if the route

between the slaves to the Master has been interrupted.  I have
considered giving a Slave the ability to self-

promote if this certain Slave detects that Master has became
unavailable.  That would also include having

to make modifications to the send_nsca IP Address on those other Slaves.
That includes the firewall and

routing adjustments being required.

 

I have looked at DNX but I am thinking that it is really designed to
cross check the hosts/services from each

of those "Nodes" to distribute the work loads.  I do not want the Slaves
to overlap each other's territory

unless a certain Slave have been self-promoted. 

 

Anyone have suggestions on a working solution or can point me to some
reading documentations of how

someone have set up a HA Nagios Master/Slaves solution?

 

Chris
