Guys I updated from nginx 1.3.9 to 1.3.10, edited my access\_log line and here it is now: _access\_log /var/www/blahblah/logs/access.log gzip buffer=32k;_ Unfortunately when I restart nginx I get this error: nginx: [emerg] unknown log format “gzip” What am I doing wrong? Thanks in advance. ---

You forgot to specify log format (“gzip” is not log format).

Thanks Valentin! _access\_log /var/www/blahblah/logs/access.log combined gzip; worked 🙂_ \*\*Last question: what does the flush variable do? Does it specify for how much times to keep the logs? 2012/12/26 Lorenzo R. [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) ---

Oh, I was forgetting: is there a way to globally set to gzip access\_log? Cause I have a lot of websites and it will be better to set this globally instead of manually changing access\_log line for every vhost 🙂 2012/12/26 Lorenzo R.

If you want to change it for a lot of access log files, you could use automated editing tools like sed, awk… wbr, Valentin V.
