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.

OPTIONS


-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
