<h1><a name="variables">VARIABLES</a></h1>
85
<p>Supported probe-specific variables:</p>
87
<dt><strong><a name="item_binary">binary</a></strong><br />
90
The location of your echoping binary.
93
<p>Default value: /usr/bin/echoping</p>
96
</dd><dt><strong><a name="item_forks">forks</a></strong><br />
99
Run this many concurrent processes at maximum
102
<p>Example value: 5</p>
105
<p>Default value: 5</p>
108
</dd><dt><strong><a name="item_offset">offset</a></strong><br />
111
If you run many probes concurrently you may want to prevent them from
112
hitting your network all at the same time. Using the probe-specific
113
offset parameter you can change the point in time when each probe will
114
be run. Offset is specified in % of total interval, or alternatively as
115
'random', and the offset from the 'General' section is used if nothing
116
is specified here. Note that this does NOT influence the rrds itself,
117
it is just a matter of when data acqusition is initiated.
118
(This variable is only applicable if the variable 'concurrentprobes' is set
119
in the 'General' section.)
122
<p>Example value: 50%</p>
125
</dd><dt><strong><a name="item_step">step</a></strong><br />
128
Duration of the base interval that this probe should use, if different
129
from the one specified in the 'Database' section. Note that the step in
130
the RRD files is fixed when they are originally generated, and if you
131
change the step parameter afterwards, you'll have to delete the old RRD
132
files or somehow convert them. (This variable is only applicable if
133
the variable 'concurrentprobes' is set in the 'General' section.)
136
<p>Example value: 300</p>
139
<p>Supported target-specific variables:</p>
141
<dt><strong><a name="item_extraopts">extraopts</a></strong><br />
144
Any extra options specified here will be passed unmodified to echoping(1).
147
<p>Example value: -some-letter-the-author-did-not-think-of</p>
150
</dd><dt><strong><a name="item_fill">fill</a></strong><br />
153
The ``-f'' <code>echoping(1)</code> option.
156
<p>Example value: A</p>
159
</dd><dt><strong><a name="item_ipversion">ipversion</a></strong><br />
162
The IP protocol used. Possible values are ``4'' and ``6''.
163
Passed to <code>echoping(1)</code> as the ``-4'' or ``-6'' options.
166
<p>Example value: 4</p>
169
</dd><dt><strong><a name="item_pings">pings</a></strong><br />
172
How many pings should be sent to each target, if different from the global
173
value specified in the Database section. Note that the number of pings in
174
the RRD files is fixed when they are originally generated, and if you
175
change this parameter afterwards, you'll have to delete the old RRD
176
files or somehow convert them.
179
<p>Example value: 5</p>
182
</dd><dt><strong><a name="item_priority">priority</a></strong><br />
185
The ``-p'' <code>echoping(1)</code> option.
188
<p>Example value: 6</p>
191
</dd><dt><strong><a name="item_size">size</a></strong><br />
194
The ``-s'' <code>echoping(1)</code> option.
197
<p>Example value: 510</p>
200
</dd><dt><strong><a name="item_timeout">timeout</a></strong><br />
203
The ``-t'' <code>echoping(1)</code> option.

224
The ``-w'' <code>echoping(1)</code> option.
