No, I don’t mean status codes on the HTTP level. Status code 444 is
not an error per se that would be sent to the error log, it is a valid
status code sent from the server to the client. To the client that
might be considered an error, but not to Nginx.
I mean errors on a lower level, i.e. the level of the nginx daemon
E.g. stuff like this:
2020/06/14 13:13:59 [alert] 700#700: *998 open socket #13 left in connection 11
2020/06/14 13:13:59 [alert] 700#700: *4118 open socket #4 left in connection 13
2020/06/14 13:13:59 [alert] 700#700: *4169 open socket #17 left in connection 16
2020/06/14 13:13:59 [alert] 700#700: aborting
It would be useful to me to be able to trigger such messages, so that
I can verify that they are sent to the right destination.
E.g. if I have the following stanza in my config:
error_log /srv/nginx/error.log warn;
Then messages of the warn/error/crit/alert/emerg levels should be
logged and written to the file /srv/nginx/error.log (a file which is
separate from the access log).
I hope it is clearer now what I meant :)
