I want to generate my own XML, simulating data from an agent, why doesn’t my XML work?

The best option here, is just looking at a real XML and trying to imitate it. The most basic items are showed here:

A basic XML could be, for example something like this:

<agent_data agent_name="testxml" timestamp="2010-09-06 22:10:00" version="1.0" os="Other"
os_version="1.0" interval="300">
<module>
<name>5min</name>
<type>generic_data</type>
<data>73.3</data>
</module>
</agent_data>

A more advanced XML, with multi-data series, should look like this one:

<agent_data agent_name="testxml" timestamp="2010-09-06 21:10:00" version="1.0" os="Other"
os_version="1.0" interval="300">
<module>
<name>Multi Data Sample</name>
<type>generic_data</type>
<datalist>
<data>
<value>73.3</value>
<timestamp>2010-09-06 21:00:00</timestamp>
</data>
<data>
<value>13.3</value>
<timestamp>2010-09-06 21:05:00</timestamp>
</data>
</datalist>
</module>
</agent_data>

Just put a file called xxxxxxx.data in Pandora FMS’s incoming section directly and it will be processed by the data server.
