Overview
This page explains how to configure the Catalina log rotation. This practice can prove efficacious in situations such as "disk is full" or when a user has a specific need for custom rotation rules.
Use Information
The current active log, as well as older files, can be found here: /var/log/tomcat.
The Catalina rotation log may already have default settings present.
Instructions
1. ssh to the Matillion host and become root using the sudo su - command.
2. Create the /etc/logrotate.d/tomcatrotate file with the following contents:
Important Information
Please note that the file to be created in step 2 does not yet exist, and therefore you need to create it yourself as the step suggests.
/var/log/tomcat*/catalina.out {
copytruncate
weekly
dateext
rotate 52
compress
missingok
create 0644 tomcat tomcat
}
The above configuration maintains the last 52 files. Please note that size takes precedence over time.
3. Manually run the "rotate logs" command:
sudo logrotate -f /etc/logrotate.d/tomcatrotate
To validate that the manual log rotation was successful, run the following command from the SSH session:
sudo ls -trl /var/log/tomcat
In the command line results, you should see an archived catalina.out file with the following name format: catalina.out-YYYYMMDD.gz where YYYYMMDD represents the current date.
You will now see a very small (or possibly even empty) catalina.out file.
Step 3 (above) will rotate the logs. Please note that from that point, rotation will happen automatically.
