Distributed Monitoring with passive Host checks

[Hochberg, Keith]

I got around this by using the check_by_ssh plugin and executing the
host check from a trusted server in each environment.  It does create
additional and unneeded dependencies but it has sufficed until 2.0 comes
out.  If you figure anything else out please let me know!

Subject: [Nagios-users] Distributed Monitoring with passive Host checks


Guys and Gals,

following situation. We have multiple remote sites (currently over 400
but expanding to over 2000 in the next 3 years) which use internally
exactly the same adressing scheme. Don't ask why the same Addresses, but
be assured that i pointed already a 45 Magnum at the idiot who designed
this. Anyway back to the prob. 

I want to remotely monitor all hosts in every site (well not all because
that would already now mean about 100k hosts), but i don't have direct
access at the moment into each site. Also i would need to include a
second Firewall to open a VPN tunnel to our HQ where the central server
sits. An additional Firewall would cost. I hear you all crying out
already why 2 Firewalls, but unfortunately the sites use PIX Firewalls
which is a piece of shi* and can't do split tunnels and NAT at the same
time, thankfully i will sooner or later be able to use a Nokia with CP
FW-1 for each site. 

How can i do passive host checks from the central server without
spending loads of development time, loads of money and have loads of
headaches? Anybody did that already? Ohhh and no i can't wait a minimum
of 12 months until Nagios 2.0 comes out.

Any ideas, pointers etc. highly welcome. If anybody has an idea just
contact me and i can pass more details on about the Network setup.

Cheers in advance,

Tom
