Hi, to debug my locations, I have a variable in my configuration that I reference during logging. The log format, included from nginx.conf:
log_format mylogformat '$remote_addr - $remote_user [$time_local] $request ' '"$status" $body_bytes_sent "$http_referer" ' '"$http_user_agent" domain: $host branch: $pat'; Unfortunately, I cannot set the variable $pat already in nginx.conf, but in my virtual server configuration, I set it like this: server { listen 1.2.3.4:80 default_server; server_name www.example.com; charset utf-8; set $pat "-"; # rest of configuration here, eg.: location = / { set $pat "homepage"; # do something special } # more stuff... } So far, my understanding is that the variable $pat should be _always_ defined, right? Well... I find this in the error log: [warn] 11092#0: *15719589 using uninitialized "pat" variable while logging request, client: 4.3.2.1, server: www.example.com For a lot of requests, the value of the variable does appear in the log file, but for a good proportion, it doesn't. I would like to have this variable always set properly. Can it be a timing question? I get between ~5 and below 100 requests per second. The machine doesn't look anywhere near loaded, though (CPU utulization is under 5%). My software is nginx-full 1.2.1-2.2+wheezy1, on an amd64 VM. TIA! Kind regards, --Toni++ _______________________________________________ nginx mailing list nginx@nginx.org http://mailman.nginx.org/mailman/listinfo/nginx
