Hi Bryan,
Thank you for your quick reply! I have tried both approaches you have
propose.
using traffic_ctl to zero the stat, but it does not have any effect, I tried to
zero several statistics, then I get the value, it is still there. I have also
tried traffic_ctl metric clear, it does not working either.
As for removing records.snap,
it gives me "Error getting stat: proxy.process.http.100_responses when calling
TSRecordGetInt() failed: file "traffic_top/stats.h", line 281”
sometimes the error disappears if I rerun traffic_top, but sometimes it will
always give this error.
Any thoughts why?
Best,
Jason
