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
# The following variables can be overridden in each target section
/ˆinflux_.+/ = influx_location = In the basement
# [...]
*** Targets ***
probe = basevars # if this should be the default probe
# [...]
+ mytarget
# probe = basevars # if the default probe is something else
host = my.host
/ˆinflux_.+/ = influx_location = In the basement

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 above mentioned 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 acquisition 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.
