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:
- 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
- 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
- url
-
The URL to be requested from the web cache.
Example value: http://www.example.org/
This setting is mandatory.
- waittime
-
The ``-w'' echoping(1) option.
Example value: 1
