NAME

       Smokeping::probes::basevars - Another Base Class for implementing SmokePing Probes

OVERVIEW

       Like Smokeping::probes::base, but supports host-specific variables for the probe.

SYNOPSIS

        *** Probes ***

        +basevars

        offset = 50%
        pings = 20
        step = 300

        # [...]

        *** Targets ***

        probe = basevars # if this should be the default probe

        # [...]

        + mytarget
        # probe = basevars # if the default probe is something else
        host = my.host

DESCRIPTION

       Provides the method `targets' that returns a list of hashes.  The hashes contain the
       entries:

       addr
           The address of the target.

       vars
           A hash containing variables defined in the corresponding config section.

       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.

VARIABLES

       Supported probe-specific variables:

       offset
           If you run many probes concurrently you may want to prevent them from hitting your
           network all at the same time. Using the probe-specific offset parameter you can change
           the point in time when each probe will be run. Offset is specified in % of total
           interval, or alternatively as 'random', and the offset from the 'General' section is
           used if nothing is specified here. Note that this does NOT influence the rrds itself,
           it is just a matter of when data acqusition is initiated.  (This variable is only
           applicable if the variable 'concurrentprobes' is set in the 'General' section.)

           Example value: 50%

       pings
           How many pings should be sent to each target, if different from the global value
           specified in the Database section. Note that the number of pings in the RRD files is
           fixed when they are originally generated, and if you change this parameter afterwards,
           you'll have to delete the old RRD files or somehow convert them.

           Example value: 20

       step
           Duration of the base interval that this probe should use, if different from the one
           specified in the 'Database' section. Note that the step in the RRD files is fixed when
           they are originally generated, and if you change the step parameter afterwards, you'll
           have to delete the old RRD files or somehow convert them. (This variable is only
           applicable if the variable 'concurrentprobes' is set in the 'General' section.)

           Example value: 300

BUGS

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