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.
- apachetop -f /var/logs/httpd/access.log
