VARIABLES
Supported probe-specific variables:
binary
The location of your echoping binary.
Default value: /usr/bin/echoping
forks
Run this many concurrent processes at maximum
Example value: 5
Default value: 5
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%
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
Supported target-specific variables:
dns_request
The DNS request (domain name) to be queried.
Example value: example.org
This setting is mandatory.
dns_tcp
The echoping_dns '--tcp' option: use only TCP ('virtual circuit').
Enabled if specified with a value other than 'no' or '0'.
Example value: yes
dns_type
The echoping_dns '-t' option: type of data requested (NS, A, SOA
etc.)
Example value: AAAA
Default value: A
extraopts
Any extra options specified here will be passed unmodified to
echoping(1).
Example value: -some-letter-the-author-did-not-think-of
ipversion
The IP protocol used. Possible values are "4" and "6". Passed to
echoping(1) as the "-4" or "-6" options.
Example value: 4
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: 5
plugin
The echoping plugin that will be used. See echoping(1) for details.
This can either be the name of the plugin or a full path to the
plugin shared object.
Example value: /path/to/dns.so
Default value: dns
pluginargs
Any extra arguments needed by the echoping plugin specified with
the pluginname variable. These are generally provided by the
subclass probe.
Example value: -p plugin_specific_arg
priority
The "-p" echoping(1) option.
Example value: 6
timeout
The "-t" echoping(1) option.
Example value: 1
Default value: 5
tos The "-P" echoping(1) option.
Example value: 0xa0
waittime
The "-w" echoping(1) option.
Example value: 1
