syslog-ng and nginx logs to mysql
I can help you to write nginx access log to postgres. Lets go Nginx log format
log_format logtodb '$time_iso8601;$http_host;$remote_addr;$http_x_forwarded_for;$request_method;$request;$status;$body_bytes_sent;$http_referer;$request_time;$upstream_http_x_cache;$uri;$upstream_addr;$host;$upstream_response_length;$upstream_status;$server_name;$newurl;$upstream_response_time';
access_log /var/log/nginx/access_logtodb.log logtodb;
Let's go.
Configure syslog-ng
nano /etc/syslog-ng/syslog.ng

So couple of days ago I asked how to log php and nginx logs to centralized MySQL database, and m0ntassar gave a perfect answer :) cheer !
The problem I am facing now is that I can not seem to get it working.
syslog-ng version:
# syslog-ng --version syslog-ng 3.2.5
This is my nginx log format:
log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"';
syslog-ng source:
source nginx { file( "/var/log/nginx/tg-test-3.access.log" follow_freq(1) flags(no-parse) ); };
syslog-ng destination:
destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("superpasswd") database("syslog") table("nginx") columns("remote_addr","remote_user","time_local","request","status","body_bytes_sent","http_ referer","http_user_agent","http_x_forwarded_for") values("$REMOTE_ADDR", "$REMOTE_USER", "$TIME_LOCAL", "$REQUEST", "$STATUS","$BODY_BYTES_SENT", "$HTTP_REFERER", "$HTTP_USER_AGENT", "$HTTP_X_FORWARDED_FOR")); };
MySQL table for testing purposes:
CREATE TABLE `nginx` ( `remote_addr` varchar(100) DEFAULT NULL, `remote_user` varchar(100) DEFAULT NULL, `time` varchar(100) DEFAULT NULL, `request` varchar(100) DEFAULT NULL, `status` varchar(100) DEFAULT NULL, `body_bytes_sent` varchar(100) DEFAULT NULL, `http_referer` varchar(100) DEFAULT NULL, `http_user_agent` varchar(100) DEFAULT NULL, `http_x_forwarded_for` varchar(100) DEFAULT NULL, `time_local` text, `datetime` text, `host` text, `program` text, `pid` text, `message` text ) ENGINE=InnoDB DEFAULT CHARSET=latin1
Now first thing that goes wrong is when I restart syslog-ng:
# /etc/init.d/syslog-ng restart Stopping syslog-ng: [ OK ] Starting syslog-ng: WARNING: You are using the default values for columns(), indexes() or values(), please specify these explicitly as the default will be dropped in the future; [ OK ]
I have tried creating a file destination and it all works fine, and then I have tried replacing my destination with:
destination d_sql { sql(type(mysql) host("127.0.0.1") username("syslog") password("kosmodromas") database("syslog") table("nginx") columns("datetime", "host", "program", "pid", "message") values("$R_DATE", "$HOST", "$PROGRAM", "$PID", "$MSGONLY") indexes("datetime", "host", "program", "pid", "message")); };
Which did work and it was writing stuff to mysql,
The problem is that I want to write stuff to in exact format as nginx log format is.
I assume that I am missing something really simple or I need to do some parsing between source and destination.
Any help will be much appreciated :)
