I can't get my NGINX logs to be parsable by logstash.

NGINX config:

log\_format main '"$http\_x\_forwarded\_for - $remote\_user [$time\_local]" "$host" "$request" "$status" "$bytes\_sent" "$http\_referer" "$http\_user\_agent" "$cookie\_client\_id" "$request\_time"';

Example log line:

"194.76.219.19 - - [17/Apr/2018:09:58:39 +0200]" "[www.example.com](http://www.example.com)" "GET /?ping HTTP/1.1" "200" "62786" "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10\_12\_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36" "3294aeff1d3031a4c880ac7497688473" "0.409"

Currently I'm getting messages like:

Provided Grok expressions do not match field value: ["194.76.219.19 - - [17/Apr/2018:09:58:39 +0200]" "[www.example.com](http://www.example.com)" "GET /?ping HTTP/1.1" "200" "62786" "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10\_12\_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36" "3294aeff1d3031a4c880ac7497688473" "0.409"]

I would use dissect rather than grok, but what grok pattern are you trying to use?
