       apachetop - display real-time web server statistics


       apachetop  [-f  filename]  [-H  hits | -T time] [-q] [-l] [-s segments]
       [-p] [-r secs]


       ApacheTop watches a logfile generated by Apache (in standard common  or
       combined logformat, and generates human-parsable output in realtime.

       -f logfile
              Select  which file to watch.  Specify this option multiple times
              to watch multiple files.

       -H hits | -T time
              These options are mutually exclusive. Specify only one,  if  any
              at  all.  They  work  as follows. ApacheTop maintains a table of
              information internally containing all the  relevant  information
              about  the hits it’s seen. This table can only be a finite size,
              so you need to decide how big it’s going to  be.  You  have  two
              options.   You  can  either: Use -H to say "remember <this many>
              hits" or   Use -T to say  "remember  all  hits  in  <this  many>
              seconds"  The default (at the moment) is to remember hits for 30
              seconds.  Setting this too large (whichever option  you  choose)
              will  cause  ApacheTop  to use more memory and more CPU time. My
              experimentation finds that remembering no more than around  5000
              requests works well.

       -q     Instructs ApacheTop to keep the querystrings, not remove them.

       -l     Instructs  ApacheTop  to  lowercase all URLs, thus /FOO and /foo
              are treated as the same and accumulate the same statistics.

       -s segments
              Instructs ApacheTop to only keep the first <segments>  parts  of
              the  path.  Trailing slashes are kept if present. Statistics are
              then merged for each truncated url.

       -p     Instructs ApacheTop to keep the protocol  (http://  usually)  at
              the  front  of  its’  referrer  strings.  Normal behaviour is to
              remove them to give more room to more useful information.

       -r secs
              Set default refresh delay, in seconds.
