Tomcat Access Logs

Site24x7 AppLogs provides easy management of Tomcat access logs by providing unique separation of log information into fields such as remote access, remote user, date & time, method, request-URI, protocol, status, and bytes sent. Site24x7 allows you to gather, and analyze log information quickly and efficiently. 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, Tomcat access 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/*tomcat*/*access*.txt

:

C:\*tomcat*\logs\*access*.txt

Log pattern

$RemoteAddress$ - $RemoteUser$ [$DateTime:date$] \"$Method$ $RequestURI$ $Protocol$\" $Status:number$ $BytesSent:number$

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

Sample log

127.0.0.1 - - [19/Jul/2017:23:35:30 +0530] \"GET /manager/status HTTP/1.1\" 401 2473

The above sample log can be separated into 8 fields, each of which will take its respective value from here and will then be uploaded to Site24x7.
