Nginx log format - remove space after a variable

Question

Here's an example Nginx log format:

  log_format mylog '$request $request_time ms'

which will show something like GET /foo 10 ms and would be nicer if it showed GET /foo 10ms

Is there any way to remove the space after the $request_time variable. e.g. something like bash's ${request_time}ms.

Answer 1

To my surprise, the bash style actually works 😊

 log_format mylog '$request ${request_time}ms'
