Rotating logs

You can rotate logs by running "logger rotate" on the CLI.

You can do this from cron by putting the following in a cron job:

/usr/sbin/asterisk -r -x 'logger rotate'

On Win32 platform only you can do the following:

If you want to rotate your logs (for example starting a new log every day), use the windows scheduler. Add a new scheduled item, (eg: midnight every day / week / month) to run, and till it to run RotateLogs.vbs This script will tell Asterisk to create a new log, and then rename the old log in standard windows log format (eg: msg_YYYYMMDD.log).

The RotateLogs.vbs script file should be downloaded from Telium and copied anywhere on your disk. Edit the script for to modify the constants at the top of the file, to tell where you placed asterix.exe, where your logs files are, etc.

Then that's it!
