LUA log format

[Martin Gee]

I'm using the directive:

error_log syslog:server=127.0.0.1,tag=app1tag info;

In LUA code I'm using:

ngx.log(ngx.INFO, auditstuff)

Which generates: 

Dec 11 01:42:08 spg-dev2 app1tag: 2014/12/11 01:42:08 [info] 26544#0: *704 [lua] authSession.lua:31: audit(): "USER_REQUEST_AUTHZ" SESSION_ID:"_9d25b0d4a16ae6fbd33c2f1c9129e3b26e433a8471" SUBJECT:"us...@gmail.com" RESULT:"ALLOW" RESULT:"NA - UserName=us...@gmail.com RemoteIP=10.123.123.123 RelayDomain=app1.spg-dev2.domain.info firstName=Martin lastName=Gee Groups=Portal Sales Group:Portal Admin Group:Portal Authorizer Group:Everyone ", client: 10.123.123.123, server: app1.spg-dev2.domain.info, request: "GET /logo.png HTTP/1.1", host: "app1.spg-dev2.domain.info", referrer: "https://app1.spg-dev2.domain.info/"

My question,  can we define our own log format while logging via ngx.log .... (syslog)?

Well, ngx.log() is for error logging. And it just invokes nginx core's
error logger, which does not support custom format, unlike the access
logging.

On suggestion is to use nginx's access logger for this or just use
lua-resty-logger-socket with which you have the maximum freedom:
