Yes, I want it to run every 15 minutes and only add new events which have appeared in the last 15 minutes.

Yes the log file rotates at present its approximatly once a day, when the file rotates the previous one is also gziped. The rotation isn't synced with my script as its based on volume. If we can examine the old log file in the case of rotation that would be extremely helpful.

15 minutes of data before the time on the clock.

FAIL2BAN(1)						      General Commands Manual						       FAIL2BAN(1)

NAME

       fail2ban - a set of server and client programs to limit brute force authentication attempts.

DESCRIPTION

       Fail2Ban consists of a client, server and configuration files to limit brute force authentication attempts.

       The  server  program  fail2ban-server is responsible for monitoring log files and issuing ban/unban commands.  It gets configured through a
       simple protocol by fail2ban-client, which can also read configuration files and issue corresponding configuration commands to the server.

       For details on the configuration of fail2ban see the jail.conf(5) manual page.  A jail (as specified  in  jail.conf)  couples  filters  and
       actions definitions for any given list of files to get monitored.

       For details on the command-line options of fail2ban-server see the fail2ban-server(1) manual page.

       For details on the command-line options and commands for configuring the server via fail2ban-client see the fail2ban-client(1) manual page.

       For  testing  regular  expressions  specified  in  a filter using the fail2ban-regex program may be of use and its manual page is fail2ban-
       regex(1).

LIMITATION

       Fail2Ban is able to reduce the rate of incorrect authentications attempts however it cannot eliminate the  risk	that  weak  authentication
       presents.  Configure services to use only two factor or public/private authentication mechanisms if you really want to protect services.

       A  local  user  is able to inject messages into syslog and using a Fail2Ban jail that reads from syslog, they can effectively trigger a DoS
       attack against any IP. Know this risk and configure Fail2Ban/grant shell access accordingly.
