Collection Interval will not be considered by check a resource

Hi,

i've wrote a plugin for Hyperic which calls phonenumbers via modem.

This check should be executed once in a hour, so i configured the default collection interval for this plugin to 1 hour for each metric.

The Hyperic agent for this plugin executes a exe file with a console output. This woks fine.

But in my log file i create, i see that the check is not be executed in this interval of 1 hour. Hyperic executes it approximately every 10 minutes.

Could anyone help me? Where can i set a real execution interval?

Thanks,

Dominik
