NGINX Access Logs

Sat Jan 10 14:50:56 UTC 2015

Hi guys,

I'm new to nginx. Can anyone explain what does  - - - "-" "-" "-" "-" -
means in the access logs? Been getting lots of this in the log file.
Would like to know if this is the cause of nginx to show that there's a
spike in traffic through the nginx graph. Example of log below:

[12/Feb/2014:11:25:28 +0800] "POST /...svc HTTP/1.1" 200 274 1.68 870 0.008
0.002 192.168.10.71:84 - - - "-" "-" "-" "-" -

HTTP/1.1" 200 274 1.68 869 0.026 0.006 10.14.241.70:84 - - - "-" "-" "-" "-"
-
