Cacti Plugin : Scheduling RRD Export

This plugin will export rrd file to text format to use in another system. It let’s you create a schedule then add datasources to each schedule.

I want to export data from cacti to Splunk. After some research I found mirage plugin however mirage export data from every datasource and every poll period. This create a lot of performance issue because my system have a few ten of thousand poller. I just want to export some of them and don’t need it realtime, once a day or a week should be enough. So, that’s a purpose of this plugin.
