Logging Elasticsearch HTTP API Requests with Nginx

nginx.conf

worker_processes  1;

error_log /var/log/nginx/error.log;

events {
    worker_connections 1024;
}

http {
    log_format es '$remote_addr - $remote_user [$time_local] '
    '"$request" $status $body_bytes_sent'
    '"$http_referer" "$http_user_agent" {$request_body}';
    access_log /var/log/nginx/access.log es;

    upstream elasticsearch {
        server 10.250.250.1:9200;
    }

    server {
        listen 8080;
        location / {
            proxy_http_version 1.1;
            proxy_set_header Connection "";
            proxy_connect_timeout 5s;
            proxy_read_timeout 10s;
            proxy_pass http://elasticsearch;
        }
    }
}

Hi, How to print "\x0A" directly, do not line feed?

like this:
log_format log_json escape=json '{"timestamp": "$time_local",'
'"remote_addr": "$remote_addr",'
'"referer": "$http_referer",'
'"request": "$request",'
'"status": "$status",'
'"byte": "$body_bytes_sent",'
'"agent": "$http_user_agent",'
'"x_forwarded_for": "$http_x_forwarded_for",'
'"up_addr": "$upstream_addr",'
'"up_host": "$upstream_http_host",'
'"up_resp_time": "$upstream_response_time",'
'"request_body": "$request_body",'
'"request_time": "$request_time"}';

make sure your nginx version >= 1.11.8
