Hi,
Are you talking about the export of data from the device to the Collector, or the interval period that the collector writes to file?
If it is the latter, then this is configured in the thread on the Collector. You use NFUI to reconfigure the interval for that particular thread.
If you are talking about the export of NF data from the router, then I don't think this is configurable. It is delivered over UDP using a cache.
I'm not sure about the Analyzer, as we don't use it.
Regards.
