Nagios Support Forum

Hi Team,

I would like to know about the nagios.log. I have noticed that every hour logs are rotated and moved the directory archives. This logs are rotated every hour as it is configured as "log_rotation_method=h".

Now my queries is:
2. I want to roatate logs for ever 15 minutes and keep retention for 30 days.

Log Rotation Method can only be set to one of the following

Format: log_rotation_method=<n/h/d/w/m>
Example: log_rotation_method=d

This is the rotation method that you would like Nagios to use for your log file. Values are as follows:

n = None (don't rotate the log - this is the default)
h = Hourly (rotate the log at the top of each hour)
d = Daily (rotate the log at midnight each day)
w = Weekly (rotate the log at midnight on Saturday)
m = Monthly (rotate the log at midnight on the last day of the month)

And nagios doesn't have any mechanism to remove logs as they are required to calculate availability data, if you want to remove old logs, you would need to write a a script and setup a cron to perform this action.
