NAME
apachetop - display real-time web server statistics
SYNOPSIS
apachetop [-f filename] [-H hits | -T time] [-q] [-l] [-s segments]
[-p] [-r secs]
DESCRIPTION
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.
EXAMPLES
apachetop -f /var/logs/httpd/access.log
