Hello, I need to capture all IO events. I've tried biosnoop and it's working fine! But sometimes I'm getting this error:
2.004204001 kworker/0:3 26040 xvdb W 41950344 65536 0.34
Lost 10 samples
2.104204001 kworker/0:3 26040 xvdb W 31950344 65536 0.28
I've found, that it produced here:
https://github.com/iovisor/bcc/blob/master/src/cc/perf_reader.c#L238
But I can't setup debug evironment for bcc and can't get detailed information about this issue.
How ca I avoid this issue? How can I increase ring-buffer for perf events?
