/var/log full

[hakaies]

I am developing some PHP web pages that run directly on my RevPi Connect 4 4GB/32GB. I noticed this morning that the apache logs had filled up the /var/log mount.
I realize this is more of a general linux sysadmin question. I am looking for suggestions on how best to resolve this. Expand /var/log volume? Is log rotate executing properly?

Hello hakaies!

I generally view 50M of logs as quite a lot. We do ship configuration files for logrotate that rotate files for apache daily, keeping 14 days of logs compressed on disk.

How much is your application logging? If it's a lot, try tuning your logging parameters to log less information (i.e. decrease the logging level).
Do the logs indicate some form of error that might be written over and over that is accumulating in the logs?

If there are no errors and your application can't or shouldn't be logging less, you can, as a last resort, customize the apache configuration for logrotate in

Code: Select all

/etc/logrotate.d/apache2

to keep less than 14 days of logs, for example only 7 days might be fine for your use case, or tune another parameter at your will. For more information on the format of logrotate configuration files have a look at

Code: Select all

logrotate(8)

(

Code: Select all

man 8 logrotate

).

That would be my approach. I hope this helped!
