Unable to graph single value from a script

Post by kernelg »

Hello all,

I am migrating a very old cacti ( 0.8.8 ) into 1.2.5. A while ago I had written a number of scripts to monitor some processes and environmental that were simple: a shell script and a single value comes back. I am struggling to convert all those graphs into 1.2.5 as cacti has evolved.

I read the documentation, so I created the input method, a data source template, device template, graph template, data query, the device, and finally the graph. it just doesn't work. To do this used to be simple, now you need so many constructs including an XML file for the data queries. At this point I am assuming my XML is malformed as I can't select the associated graph template from the drop-down.

Is there any example of an XML file showing how to collect a single variable from a script? What could be causing the associated graph template not to show the one I created?

Here is the current XML I have:

<query>
<name>Get humidity</name>
<description>humidity</description>
<script_path>/var/www/html/cacti/scripts/wduckhumm</script_path>
<fields>
<humidity>
<name>Humidity</name>
<direction>output</direction>
<query_name>Humidity</query_name>
</humidity>
</fields>
</query>


All the documentation (outside the cacti manual) I found describes the way I used to get it done, nothing has been updated to the new cacti. I have included the troubleshooting output of one of the scripts.


Please help!

With area graphs, you need two polling cycles to see data.

For those wondering, I'm still here, but lost in the shadows. Yearning for less bugs. Who want's a Cacti 1.3/2.0? Streams anyone?
