lua m.log(2, "4444") where is the log message? #3035
Description
docker run --privileged --rm -ti owasp/modsecurity-crs:3.3.5-nginx-alpine-202401080101
/etc/modsecurity.d # grep SecRule setup.conf
SecRuleScript "/tmp/2.lua" "id:23333,deny"
/etc/modsecurity.d/owasp-crs # cat /tmp/2.lua
function main()
--error("4444")
--print("4444")
m.log(1,"4444")
m.log(2,"4444")
return nil;
end
I am sure lua script have been exectued, but i checked "console output"、"nginx error log", and can not found the log message "4444".
So where is the log message?

Revisiting this one.
m.log(level, text)writes to the ModSecurity debug log at the given level (src/engine/lua.cc), nothing else; it never reaches the nginx error log or the console. To see it, setSecDebugLogto a file andSecDebugLogLevelto at least the level you pass.Let's close this one, with that sentence added to the Lua documentation.

Thanks @fzipi,
I sent a PR to documentation as you suggested, now closing this one.
