When/how does log rotation happen?

[jonm]

I just noticed that in /var/log/system, latest.log isn't actually the latest.
When/how does log rotation and the creation of the symlink happen, please?

Code: [Select]

-rw-------  1 root  wheel   16854 Aug 30 23:57 system_20230830.log
lrwxr-x---  1 root  wheel      35 Aug 31 11:01 latest.log -> /var/log/system/system_20230830.log
-rw-------  1 root  wheel    8438 Aug 31 11:57 system_20230831.log

Once per hour. But it only works after the file was created, which doesn't happen before something is being logged that day for the particular facility.

You can also do it manually from the command line.

# configctl syslog archive


Cheers,
