[hobbit] Redundant Hobbit Servers

[Kelley, Scott]

We are moving to running all our monitoring services in (VMWare) virtual
machines.  The vm's are backed up each night to a NAS share.

If the physical server dies, no big deal I can just start the vm on
another host connected to the same SAN.
If the SAN dies (unlikely), I can restore the vm from the backup on some
other host.

We also run Sitescope, which alerts us if BigBrother/Hobbit dies (and
vice versa).

Subject: [hobbit] Redundant Hobbit Servers

I'm interested in knowing what everyone is doing for redundancy.  I
currently have 2 hobbit servers and each one performs the same tests as
the other. 

I find this to be a bit wasteful and am looking for the active/passive
type of configuration that has been talked about on this list before.

This configuration works fine, except for alerting.  In order to not be
overwhelmed by messages, I only have one hobbit server performing the
alerting task, the other only sends alerts on the other hobbit host.

I have considered using the "depends=" test, but then I have to maintain
two separate bb-hosts files, rather than copying and pasting from one to
the other.

Is there a better way than what I'm doing?  My goal is to have both
servers configured the same, as much as possible, and have only one of
them at a time send me alerts.  

I'd love to know what you guys are doing to get around these limits.  I
could easily have missed something in the newest update that solves this
problem, but I haven't seen it yet.

Thanks for your thoughts on this subject.

Michael
