[Nagiosplug-help] SMP

[Donald A. McCallum]

Tom,
Yes, were trying to monitor 12,000 virtual hosts, each with their own
real static ip. They are running on 4 physical computers on a DS3.

This is for a web hosting company.  Since the customers are paying for
the hosting, we do need to actually monitor each web site to ensure it
is returning a proper header.  Currently, the hosting company is doing
something similar to what your suggesting, where they are monitoring a
sample.  However, when there is actually a problem,  It is difficult for
them to locate since the monitoring is not specific enough.

How about a quick survey everybody?

What the most amount of items you have been able to successfully monitor
with a given machine & bandwidth?
(This might be interesting!)

Hello,

For SMP, no ideas, but for the check_http (I assume you mean http and 
not html ;), do you have 12000 hosts ?!
Or 12000 Virtual Hosts ? If it's VH why not only monitor one or two VHs 
on the host ?
Because if Apache goes down, all VHs will go down ...
It was only an idea, perhaps you need to monitor all your VHs for yours 
reasons ;)

But it's quite strange ;)
Regards,

Tom
