Question Log rotation time

[JuanCar]

Server operating system version

Almalinux 9.4

Plesk version and microupdate number

Plesk Obsidian 18.0.62 #2

I've set log rotation with a month frequency. So every first day month logs are rotated and compressed.
But at what time does it happen?. Can we set this time?
Yesterday, August 1, my logs were rotated at 19 hours!!!

Hello, plesk uses the https://linux.die.net/man/8/logrotate to rotate logs, according to the documentation

monthly
  Log files are rotated the first time logrotate is run in a month (this is normally on the first day of the month).

Yes I know monthly is every month, the first day. Ok. But I ask about the time in the day: 03:04:00, 15:00...
I see that every day web logs are processed at about 03:xx or 04:xx
Where are set times of day for this crontabs?

@JuanCar, just to be sure, where exactly did change the log rotation to monthly?

 

[JuanCar]

In Plesk interface I do:
Websites and Domains, find the domain whose logs i want to see, click Logs, and then click Log Rotation
Here I can choice By Size or By Time
And the question is at what time is the rotation made?
(And a similar question for daily log process: from access.log to access.log.processed)

 

[Kaspar@Plesk]

Log rotation (when rotated by time) is handled by the OS via Anacron. You can configure the time frame in which Anacron tasks are started which the START_HOURS_RANGE option in /etc/anacrontab.

If you like to read up on some background about log rotation and Anacron this article explains it pretty well:

Services that manage their own logs use the logrotate utility to rotate logs. In this article we'll look at the configuration and anacron.
