<h1><a name="variables">VARIABLES</a></h1>
86
<p>Supported probe-specific variables:</p>
88
<dt><strong><a name="item_binary">binary</a></strong><br />
91
The location of your echoping binary.
94
<p>Default value: /usr/bin/echoping</p>
97
</dd><dt><strong><a name="item_forks">forks</a></strong><br />
100
Run this many concurrent processes at maximum
103
<p>Example value: 5</p>
106
<p>Default value: 5</p>
109
</dd><dt><strong><a name="item_offset">offset</a></strong><br />
112
If you run many probes concurrently you may want to prevent them from
113
hitting your network all at the same time. Using the probe-specific
114
offset parameter you can change the point in time when each probe will
115
be run. Offset is specified in % of total interval, or alternatively as
116
'random', and the offset from the 'General' section is used if nothing
117
is specified here. Note that this does NOT influence the rrds itself,
118
it is just a matter of when data acqusition is initiated.
119
(This variable is only applicable if the variable 'concurrentprobes' is set
120
in the 'General' section.)
123
<p>Example value: 50%</p>
126
</dd><dt><strong><a name="item_step">step</a></strong><br />
129
Duration of the base interval that this probe should use, if different
130
from the one specified in the 'Database' section. Note that the step in
131
the RRD files is fixed when they are originally generated, and if you
132
change the step parameter afterwards, you'll have to delete the old RRD
133
files or somehow convert them. (This variable is only applicable if
134
the variable 'concurrentprobes' is set in the 'General' section.)
137
<p>Example value: 300</p>
140
<p>Supported target-specific variables:</p>
142
<dt><strong><a name="item_extraopts">extraopts</a></strong><br />
145
Any extra options specified here will be passed unmodified to echoping(1).
148
<p>Example value: -some-letter-the-author-did-not-think-of</p>
151
</dd><dt><strong><a name="item_fill">fill</a></strong><br />
154
The ``-f'' <code>echoping(1)</code> option.
157
<p>Example value: A</p>
160
</dd><dt><strong><a name="item_ipversion">ipversion</a></strong><br />
163
The IP protocol used. Possible values are ``4'' and ``6''.
164
Passed to <code>echoping(1)</code> as the ``-4'' or ``-6'' options.
167
<p>Example value: 4</p>
170
</dd><dt><strong><a name="item_pings">pings</a></strong><br />
173
How many pings should be sent to each target, if different from the global
174
value specified in the Database section. Note that the number of pings in
175
the RRD files is fixed when they are originally generated, and if you
176
change this parameter afterwards, you'll have to delete the old RRD
177
files or somehow convert them.
180
<p>Example value: 5</p>
183
</dd><dt><strong><a name="item_priority">priority</a></strong><br />
186
The ``-p'' <code>echoping(1)</code> option.
189
<p>Example value: 6</p>
192
</dd><dt><strong><a name="item_size">size</a></strong><br />
195
The ``-s'' <code>echoping(1)</code> option.
198
<p>Example value: 510</p>
201
</dd><dt><strong><a name="item_timeout">timeout</a></strong><br />
204
The ``-t'' <code>echoping(1)</code> option.
207
<p>Example value: 1</p>
210
<p>Default value: 5</p>
213
</dd><dt><strong><a name="item_tos">tos</a></strong><br />

The ``-P'' <code>echoping(1)</code> option.
219
<p>Example value: 0xa0</p>
222
</dd><dt><strong><a name="item_udp">udp</a></strong><br />
225
The ``-u'' <code>echoping(1)</code> option. Values other than '0' and 'no' enable UDP.
228
<p>Example value: no</p>
231
</dd><dt><strong><a name="item_waittime">waittime</a></strong><br />
234
The ``-w'' <code>echoping(1)</code> option.
