HOW TO : Sort Apache Web Logs for hits by Unique IP Addresses

Say you want to find out how many hits you are getting t0 a specific page from a particular source IP, you can use this quick collection of Linux tools to get this data

[code]grep -i "URL_TO_CHECK" PATH_TO_APACHE_ACCESS_LOG | cut -d’ ‘ -f 1 -| sort |uniq -c | sort -rn > ~/ip_report.txt[/code]

You are using

• grep to filter the string of the page you want the report on
• cut to get the IP address from the log file
• sort and uniq to sort the unique IP addresses
• and finally sort -rn to sort the data in descending order

Example :

[code]grep -i "GET /" /opt/apache/logs/access_log | cut -d’ ‘ -f 1 -| sort |uniq -c | sort -rn > ~/ip_report.txt[/code]

gets you the report of hits to the index page.
