Smokeping_probes_basevars(3) SmokePing Smokeping_probes_basevars(3)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.
