how to start nagios multiple instance

[shadih rahman]

Marc,
    Thanks for your reply.  The reason behind doing multiple instance is
described below.  Thanks

1) Previous monitoring system (survivor) was running multiple instance based
on different systems group.

2) I have been doing hostgroup and servicegroup along with contactgroup to
represent different instances of previous monitoring system.  However its
growing exponentially and seeing performance issue.  ( currently there are
8000 servicechecks.  Some of the hosts will be 20 fold on the number of
service checks run on them soon.)

3.  Ndoutils database has performance on quering some of these services.
When run different instances with separate database their data set will be
smaller and it will be easy to retain the data for longer time.
