Change polling interval for single data source.

[beerygaz]

I have a data source that is base don the output of a script. I'd like to run the script to test my dl/ul speed to my ISP - but I want it to run every 4 hours, not every 5 minutes like my SNMP polls. What is the recommended approach to having different poller intervals for different data sources?

Edit: I think I've solved the interval issue by setting the Data Source "Step" value to 14400
