NGINX Logs

Site24x7 AppLogs is an agent-based log management tool on the cloud that natively facilitates effective and simple management for NGINX logs. It separates critical data in a simple and accessible format by segregating them into components like remote address, remote user, date & time, method, request-URI, protocol, status, bytes sent, referrer, user agent, and forwardedFor.  Learn more about log management with Site24x7.

Getting started 

1. Log in to your Site24x7 account.
2. Download and install the Site24x7 Server Monitoring agent (Windows | Linux). 
3. Go to Admin > AppLogs > Log Profile and Add Log Profile.

Logs file path

Each application writes logs in different folders and files. By default, NGINX logs are sourced from the below-mentioned folder path for the respective Operating System. If you have logs in a different folder, you can mention it under the File Path to source them from that particular folder while creating a log profile.

:

/var/log/nginx/access*.log*

:

C:\nginx*\logs\access*.log

Log pattern

$RemoteAddress$ - $RemoteUser$ [$DateTime:date$] "$Method$ $RequestURI$ $Protocol$" $Status:number$ $BytesSent:number$ "$Referer$" "$UserAgent$"! "$ForwardedFor$"!

This is the default pattern defined by Site24x7 for parsing NGINX logs based on the sample log mentioned below.

Sample log

127.0.0.1 - - [18/Jul/2017:23:59:18 +0530] "GET / HTTP/1.1" 200 612 "-" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/52.0.2743.116 Safari/537.36" "-"

The above sample log can be separated into 11 fields, each of which will take its respective value from here and will then be uploaded to Site24x7.
