Designing distributed and failover architecture

[shadih rahman]

I have not implemented distributed nagios but I have failover setup.  Few
comments I want to make

1) If you are using ndoutils for backend make sure you have looked at faster
speed up option.  There is a patch for faster start up in opsview

2) if you using nsca to transfer acknowledgement and comments make sure you
do some research on that.  scalability is a problem

3) remember to understand failover architecture properly.  I have made few
mistakes when it comes to ndoutils.  your ndomod data processing option
should be different on the failover from master server.  Your master should
push configuration definitions into database but your failover should not
push theses configuration defitions in database.

4) Keep in mind scalability will be a problem.  data retention is really a
difficult problem for large setup.
