Small question about ngx.log()

[Didip Kerabat]

Can I make modification to it?

For example, I just want to output the content of my log without being prefixed with timestamp or line number?

The use case is: I'd like to log a full JSON payload to the log file.

I tried print, but it's the same as ngx.log(ngx.notice, ...)

Docs I've read:
https://github.com/openresty/lua-nginx-module#ngxlog

ngx.log hooks into the Nginx error logging subsystem, so there's no way to accomplish this directly.

You could use the Lua IO library (not recommended in high concurrency/performance sensitive environments), or have a look at something like https://github.com/cloudflare/lua-resty-logger-socket which can buffer log data and ship it to a remote TCP or UDP server (say, something like a local syslog server).

Good luck with it!
