Date variable

Server NGINX
1

Hi.

Rather than rotating logs, I name my access log files like
access-YEAR-MONTH.log.

Is this possible with nginx? I was looking a variable containing the
current date, but did not find any.

TIA,
Anders.

cron everyday at 23:55 mv path/to/your/log date +%Y%m%d.log
should do the same ^^

No, that is log rotation, and I don’t like that because one has
to do things at exactly the right time to have everything end up
in the right place.

I find it nicer to just write to the final filename right away.

Hello again.

I made the below quick patch and configuration like this:

    if ($timestamp ~ "^(\d\d\d\d)/(\d\d)/(\d\d)

(\d\d):(\d\d):(\d\d)") {
set $year $1;
set $month $2;
set $day $3;
set $H $4;
set $M $5;
set $S $6;
}

    access_log /var/log/http/$host/access-$year-$month.log;

I just glued together a few pieces that seemed about right, so I am
sure that there are all kinds of things wrong with the patch. But it
seems to mostly work, at least as an example of what I am looking for.

Is something like this possible with the stock nginx?

Cheers,
Anders.
