Data Transfer

If I wanted to measure the amount of data transfered for a particular node over a 30 day period, how would I do this? thanks

Here's the manual way:

If it's for a specific node, then you'll want to use the LocalLB::NodeAddress::get_statistics() method and pull out STATISITCS_BYTES_IN and store that in an external database/file/etc. 30 days later, query the same statistic and subtract the two.

Another option is to just zero out the statistics with the LocalLB::NodeAddress::reset_statistics() on day zero and then query that stat on any given day after day zero and that will be your total.

If you are asking if the BIG-IP keeps this information, then I think the answer is no. We do keep some global statistics over time but not on a node by node basis.

Hope this helps!
