Smokeping::probes::basevars - Another Base Class for implementing SmokePing Probes
DOC
overview => <<DOC,
Like L<Smokeping::probes::base|Smokeping::probes::base>, but supports host-specific variables for the probe.
DOC
description => <<DOC,
Provides the method `targets' that returns a list of hashes.
The hashes contain the entries:
${e}over
${e}item addr
The address of the target.
${e}item vars
A hash containing variables defined in the corresponding
config section.
${e}item tree
The unique index that `probe::base' uses for targets.
There's also the method 'vars' that returns the abovementioned
hash corresponding to the 'tree' index parameter.

bugs => <<DOC,
Uses `Smokeping::probes::base' internals too much to be a derived class, but
I didn't want to touch the base class directly.
