另有更易使用的apachetop和goaccess

 

wtop is really cool application for web server log analysis and to see server stats at a glance. It also has powerful log grepping capability. It is just like 'top' for your webserver.





It can find out number of searches or signups per seconds. It can also create histogram of response time. There is also another tool called logrep a powerful command-line program for ad-hoc analysis and filtering for log files. You can dig up lots of information using wtop tools.

You need Python version 2.5 to run wtop.

Download wtop

Type the following command:

$ cd /tmp

$ wget http://wtop.googlecode.com/files/wtop-0.5.6.tar.gz 
$ tar -zxvf wtop-0.5.6.tar.gz

$ cd wtop-0.5.6

# python setup.py install

Configuring wtop

Once installed you can start using the tool immediately. You need to edit /etc/wtop.cfg file to setup parameters, Apache log files and other directives

# vi /etc/wtop.cfg

Sample configuration file:

[main]
LOG_ROOT=/var/log/lighttpd/cyberciti.biz/
LOG_FILE=access.log
DEFAULT_OUTPUT_FIELDS=ts,class,ipcnt,ip,msec,uas,url

# This must match your webserver log format. You MUST have at least %h, %r and %D
LOG_FORMAT=%h %l %u %t "%r" %>s %B "%{Referer}i" "%{User-Agent}i" %D

[wtop]
# max time before a request is logged in the "slow" column
MAX_REQUEST_TIME=5000
# minimum requests/second before a URL class appears in top mode
MIN_RPS=0.2

[classes]
# you can extend these to make any classes you wish
home=^/(?:\?.*)?$
xml=\.xml(?:\?.*)?$
js=\.js(?:\?.*)?$
css=\.css(?:\?.*)?$
img=\.(?:png|gif|jpe?g|cur|ico|bmp)(?:\?.*)?$

[patterns]
# the generic pattern is applied if a line does not match any
# of the named classes. By default it uses the top-level directory.
generic=^/([^/\?]+)

# incomplete list of known web robots
robots = r'(?:nutch|MSRBOT|translate.google.com|Feedster|Nutch|Gaisbot|Snapbot|VisBot|libwww|CazoodleBot|polybot|VadixBot|Sogou|SBider|BecomeBot|Yandex|Pagebull|chudo|Pockey|nicebot|entireweb|FeedwhipBOT|ConveraCrawler|NG/2.0|WebImages|Factbot|information-online|gsa-crawler|Jyxobot|SentinelCrawler|BlogPulseLive|YahooFeedSeeker|GurujiBot|wwwster|Y\!J-SRD|Findexa|SurveyBot|yetibot|discoveryengine|fastsearch|noxtrum|Googlebot|Snapbot|OGSearchSpider|heritrix|nutch-agent|Slurp|msnbot|cuill|Mediapartners|YahooSeeker|GrabPERF|keywen|ia_archiver|crawler.archive.org|Baiduspider|larbin|shopwiki)'

Now simply type wtop at a shell prompt:

$ wtop$

See all human traffic, enter:

$ logrep -m top -h access.log

See response times for all MSNBot homepage hits:

$ logrep -m grep -g MSNBot -i home -o status,msec,url access.log

Display the current log for traffic to pages about wordpress or themes sent from google.com

$ logrep -m tail --f 'url~wordpress|themes,ref~google.com' access.log
