Nagios: Scaling to monitor larger networks

[Dan Hopkins]

I'm suprised this works - I've tried before (and just re-tried now to
confirm), only the last members line is detected, any preceeding hosts
generate warnings of the:

Warning: Host 'xxx' is not a member of any host groups!

variety. (This is with nagios 1.3) Have you tested your config with a nagios
-v ?

fyi: our workaround was to generate multiple hostgroups when detecting
members lines breaching the 8192 byte line length (our config is generated
from a database) It's hardly ideal, but a short term fix.
