issue: 1897191 Implement extra TCP statistics

Open pasis opened this issue 5 years ago • 7 comments

VMA doesn't provide enough information to investigate TCP bottlenecks.

Collect more counters and metrics for a TCP connection and integrate them into vma_stats. This statistics will help to see internals and describe TCP behavior.

Possible improvement: Expand configure option --enable-extra-stats to --with-stats-level=<level>. The level must reflect the following values:

  • off -- don't collect and don't display any statistics, should save CPU cycles when stats are not required;
  • low -- build basic stats support (as in master)
  • high -- additionally to basics stats, build extra stats support
