[Devmon] Printer toner monitoring/dhcp monitoring

[Whilding, C. <Cra...@me...>]

I want to monitor printer toner and other consumables. This is all under
mib group 1.3.6.1.2.1.43.11.1.

=20

The problem I have is that is the level or total is not being measured
it can return negative numbers:

=20

The value (-1) means other and specifically indicates that
the sub-unit places no restrictions on this parameter.
The value (-2) means unknown. A value of (-3) means that the
printer knows that there is some supply/remaining space,
respectively."

=20

How should I go about implementing this? It could do with some sort of
if then else logic.

There is a similar problem with dhcp free addresses. We have some
disabled ranges that must be kept in place (networks are managed by
someone else's dept). As there is no oid I know of for disabled range I
want to monitor this through an exception if addresses in use and free
addresses is 0 - ignore. Currently I cant do this as exceptions only
work on the primary alias.

Its also still giving the "127.0.0.1 (insert real ip) isn't numeric in
numeric ne (!=3D) at /..../dm_test.pm line 1867/1851,<$__ANONIO__> line
198" errors. Any ideas?
