PasTmon can do that from the server side. It listens for network traffic like tcpdump and shovels all of the packet timings into a Postgres database with a nice front-end for graphs and analysis. I can't remember if the DNS plugin has filtering for different query types ( e.g. A, PTR, etc ) but it can probably be written without too much pain. See http://pastmon.sourceforge.net/ I've used it to solve web app performance problems, it should have no trouble dealing with DNS. -- Kerry _______________________________________________ Please visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list bind-users mailing list bind-users@lists.isc.org https://lists.isc.org/mailman/listinfo/bind-users
