There are a number of logfile analyzer packages that exist - two of which are Webalizer (written in C) and AWStats (written in Perl). Both should also be available through the Ubuntu repositories. These will parse your logfiles and generate reports for you to view (typically through a web browser, although, they can generate text reports as well).
Traditionally, they are setup to run automatically (e.g. via cron) and the latest report is available by accessing a particular path under your domain, and/or is emailed to you. (As you may expect, both do require some setup to produce what you want).
If you just want get a list of which IP addresses have made the most requests, a one-time bash command is likely easier than setting up either of the above. Try:
Essentially, create an array using the IP address as the index, increasing the counter with each match - and display those results with more than 10 matches. Pipe the result through
If you have already used
For instance, for a list of IP addresses that made more than 10 requests, today, between midnight and 4am (not inclusive) (presuming that data is in access.log):
If you are interested, ManageEngine has a solution called EventLog Analyzer. It will analyze Apache web server logs and generate exhaustive reports. You can try.
