You can extract interval stats using polygraph-ltrace, e.g.:

  $ ltrace --objects basic.rptm.count,basic.rptm.mean,ssl.rep.rptm.mean LOG

As I said before, there are no explicit pure HTTP stats.  You will have
to calculate it from other stats.

Stats are recorded into the binary logs at the same interval as they are
printed on the console.  The stats recording interval is controlled by
--stats_cycle option and is 5sec by default.

Polygraph-ltrace aggregates interval stats with 60sec window by default.
You can change the window length using --win_len option.

  $ ltrace --objects time,basic.rptm.mean,ssl.rep.rptm.mean --win_len 1sec LOG

This should give you output similar to the console.  You may specify
--time_unit 1sec option for relative time.  Also, you may want to output
interval object for some additional info.
