Description

In order to make debugging easier it might make sense to include the $request_id variable in error.log messages when these are associated with incoming requests.

This can currently be achieved by adding an access_log entry to the error_log file

nginx.conf

# Add spaces to mirror horizontal placement of error log's connection serial number
log_format requestid '$time_iso8601                  *$connection $request_id';

server {
  ...
  error_page 404 @404;

  location @404 {
    add_header x-request-id $request_id always;
    access_log logs/fail.error.log requestid;
    error_log  logs/fail.error.log;
  }

  location /fail {
    return 404;
  }
}

fail.error.log

2023/03/08 09:30:43 [error] 45212#4292110: *60 open() "/usr/local/nginx/html/fail" failed (2: No such file or directory), client: 127.0.0.1, server: , request: "GET /fail HTTP/2.0", host: "localhost"
