Hi:
It would be nice if we can get a weighted SLA:

Explanation:
We defined (in SLA) a hostgroup with its hosts.
But we don't like the actual behaviour of SLA:
If one host has a problem, its sla decreases; but also the hostgroup SLA in the same
amount.

What it would be nice is if we could define a value in % for each host priority in
the hostgroup SLA. By default, this parameter would be optional.

This could cause a problem: if the sum of the % values is more than 100% in a hostgroup we'll obtain wrong values.
