i use nginx as reverse proxy server , and php-fpm as fast cgi upstream.  
i found some access in nginx access log file doesen’t has a  
“$upstream\_response\_time” value but a “-” character instead , and  
also  
has “$response\_time” value.  
why ?

for example:

71.213.141.240 - 31/Oct/2012:13:09:34 +0800 POST  
/php/xyz/iface/?key=be7fc0cdf0afbfedff1e09ec6443823a&device\_id=351870052329449&network=1&ua=LT18i&os=2.3.4&version=3.7&category\_id=2&f\_ps=10&s=5&ps=30&pn=1&pcat=2&up\_tm=1351655451272  
HTTP/1.1 499 0($body\_bytes\_sent) - Dalvik/1.4.0 (Linux; U; Android  
2.3.4;  
LT18i Build/4.0.2.A.0.62) 21($content\_length) 2.448($request\_time)  
-($upstream\_response\_time) - - -

the response\_time is 2.448,but no upstream\_response\_time, the http  
response code is 499,dosen’t mean that nginx did not finish the  
“connection” and php-fpm even has no chance to “see” the access ?

The connection was closed by a client before nginx got anything  
from upstream, hence nginx closed upstream connection as well.  
The 499 status code logged to indicate this, and there is no  
$upstream\_response\_time for the same reason.
