Apan Configurations

[Jon Lyons]

Could you share that little perl scripts with those of use that suck at perl?  :) Guess I could do it in expect...

easier to maintain
than addresses through .../nagios/etc/hosts.cfg, because if not using DNS 
to resolve the hostnames
(which I don't want, to remain operational in case of DNS faults) it's at 
least one single source.

But for fellow admins having nagios configured to monitor 500+ hosts it's a 
tough thing to convert...

I guess I'll go and write a little script to extract ip-addresses and 
Nagios hostnames from
hosts.cfg and paste them to /etc/hosts, afterwards replace ip-addresses 
with corresponding
hostnames in hosts.cfg

Ralph.

Actually I don't use IP-numbers at all in Nagios, only host-names. All 
hosts I monitor in Nagios then lives in my hosts-file.
It's safe to skip the adress-statement in the host-definition and leave 
IP-numbers to /etc/hosts. You also need to set up your name-service switch 
to always look in files first (I don't yse DNS on my Nagios-server).

The benefits with this is that you have one source where IP-numbers and 
host-names are stored. The problem begins when you have many hosts, then 
your hosts-file get quite big. But I still think its easier to manage 
IP/name matching via /etc/hosts then the adress-statement in Nagios.

I would prefer to monitor by hostname since we monitor hosts with
dynamic IP addresses.
