Hello guys,

I’m looking for a good (maybe native) solution to use cronolog with  
nginx.  
I found only these two links [1]+[2], but I’m looking for a better  
solution like a module or a code upgrade.

Is a native solution in development or maybe give it a nginx patch?

Regards,

Markus “bionix”

Well you could try make a log (error/access) format with  
vhost/domain/whatever there and setup single access\_log/error\_log  
location, which would be a fifo with cronolog cronolog connected to it,  
note that I have no idea whatever nginx can write to fifo (or will  
replace it with a file instead) but worth trying, to not slow down nginx  
because of the read-fifo flow you could use ftee (find ftee.c somewhere  
on the internet) and open fifo with it forwarding stdout to cronolog.

The above solution sounds like a overkill but if you want realtime  
cronolog…

Maybe tengine is a solution. It can support pipe natively The  
documentation  
is here: [http://tengine.taobao.org/document/http\_log.html](http://tengine.taobao.org/document/http_log.html)

You can configure the cronolog ilke this:

error\_log “pipe:/path/to/sbin/cronolog  
/path/to/logs/%Y/%m/%Y-%m-%d-error\_log” warn;  
access\_log “pipe:/path/to/sbin/cronolog  
/path/to/logs/%Y/%m/%Y-%m-%d-access\_log” format;
