Req 5.1 - Zone Transfer Impact
From BIND GL issue #513
As an administrator I need to determine the impact of large zone updates on operations. I may see a drop in QPS performance and want to investigate whether this was caused by a large zone transfer. I will need to see information that will help me identify which zone, how large it is, when it was updated, so that I can see if I can adjust the configuration to ameliorate the impact of large zone transfers.
- Add metrics on the size of the IXFRs e.g. min, max and average size of IXFRs
- Add the same details to the XFR log on the master that are reported on the secondary:
- transfer of 'example.com/IN' from 127.0.0.1#7753: Transfer completed: 1 messages, 14 records, 986 bytes, 0.001 secs (986000 bytes/sec). The log on the master currently only reports that the transfer started and ended.
