Hi, I am trying to decrease the time that OVS takes to update its packet/byte counters. I was previously told that the line 898 of ofproto-dpif-upcall.c which is part of function udpif_validator is used to set the timer. The line is as follows:
// Original poll_timer_wait_until(start_time + MIN(ofproto_max_idle, 500)); //Changed poll_timer_wait_until(start_time + MIN(ofproto_max_idle, 1)); I changed it to 1 and I can now get updated counters at ~1ms frequency. However, I have noticed that after about 30 ms, there is a sudden jump and the stats handler takes a jump by about ~50ms. My controller is POX based and my timer is python datetime timer with microsecond granularity. Can anyone tell me why I see the jump? Regards, Adil
