With ZC kernel is bypassed, this means the application reads stats directly from the NIC, and usually print them under /proc/net/pf_ring/stats > I did find that when using the zbalance_ipc example program to bind two > interfaces together and then deliver that information to a single process > there was a file under /proc/net/pf_ring/stats for the process, but it did > not see to contain useful information in terms of performance. > > What is the recommended way to obtain statistics on ZC performance (or > really, app performance using ZC)? /proc is the way, please let us know what is missing under /stats that you think is useful > I notice zbalance_ipc does print statistics to the screen while running; can > these be disabled? There is no parameter at the moment, but they are not printed in daemon mode. > Would you expect zbalance_ipc to be used in a similar fashion as > pfdnaclustermaster was for DNA? Yes, they are supposed to be equivalent, do think zbalance_ipc is missing useful features available in pfdnaclustermaster?
