script query data template

[deanpence]

I've created a data query (using the Script Query input method). I create the data and graph templates, and then from the "Data Query" editing screen for that data query, I click on the associated graph template, and I get the following error under "Associated Data Templates":

Code: Select all

Warning: Variable passed to each() is not an array or object in /var/www/localhost/htdocs/cacti/data_queries.php on line 312

Any ideas? Here's my XML file, just in case:

Code: Select all

<interface>
   <name>Get Hosts' Memory Metrics</name>
   <description>Queries a host and gets memory metrics.</description>
   <script_path>|path_cacti|/scripts/cacti-query-memory</script_path>
   <arg_index>index</arg_index>
   <arg_query>query</arg_query> 
   <arg_get>get</arg_get>

      </myHost>

      <myMetric1>
         <name>Metric 1</name>
         <direction>output</direction>
         <query_name>metric1</query_name>
      </myMetric1>
      <myMetric2>

         <direction>output</direction>
         <query_name>metric2</query_name>
      </myMetric2>
   </fields>
</interface>

Also, if I try to run a Verbose Data Query in an associated device, I get a PHP error (the first line is repeated several times):

Code: Select all

Warning: preg_match() [function.preg-match]: Unknown modifier '(' in /var/www/localhost/htdocs/cacti/lib/data_query.php on line 115

Warning: Cannot modify header information - headers already sent by (output started at /var/www/localhost/htdocs/cacti/lib/data_query.php:115) in /var/www/localhost/htdocs/cacti/host.php on line 75

I'm having precisely the same problem; my XML file is of exactly the same form (though the fields and data are different).

Wow ... okay, I now know the XML file can't have been the problem. Turns out I was silly enough to spell "delimiter" correctly in the tag. That's a hell of an API bug ...
