To enable log rotation for tomcat-stdOut.log on 19.2

Hi Julie, Even am facing the same issue in 18.4. Looking forward for the solution.

We're running Cloud HA 19.2 and we do not have the same issue. We have the STDOUT log files without a date suffix and a STDOUT log file with the date suffix. Maybe contact Appian support to see if there is an issue with your environment or the logging configuration ? 

Hi Julie,

I assume that your servers are running on Windows OS.

Start the tomcat manually using start-appserver.bat and you may find some error messages which will help you to find the issue.

Make sure that the latest MS Visual C++ Redistributable is installed on the server. If not download and install it on the server and try to start again.

Hi Edwin, What's the solution for Linux box ?

Hi Sunil,

Check whether the Apache's rotatelogs is available or not in the environment. If not, install it using any package manager available in your environment. It is available as a part of apache2-utils. 

Hi Edwin, Let me check on that. Thanks for your support.

If already available and if the logs are not rotating, then open the start-appserver.sh and provide the path of the rotatelogs program. Appian will use that to rotate the log files.

On Ubuntu, I use Logrotate.

Create the following file: /etc/logrotate.d/appian-tomcat

Paste the following:

/<APPIAN_HOME>/logs/tomcat-StdOut.log{ 
    copytruncate 
    daily 
    rotate 30 
    compress 
    missingok 
    size 100M 
}

To perform a manual rotation:

logrotate -vf /etc/logrotate.d/appian-tomcat

Here are some additional notes on logrotate: https://www.digitalocean.com/community/tutorials/how-to-manage-logfiles-with-logrotate-on-ubuntu-16-04 

Hi Edwin

Our on-prem Appian server is running on Linux actually which you have kindly provided recommendation below. Thanks, much appreciated.
