Configure log file settings

You deploy TrueSight Automation Console using Docker containers. Docker uses the /var/lib/docker as the default image installation folder, which contains a json.log file for every container. Over a period of time, this json.log file becomes huge in size and occupies the entire /var file system.

 Even if TrueSight Automation Console does not use this json.log file, the /var folder may cause issues in the Automation Console environment. To avoid running into space problems, you must perform these steps:

1. To verify the current file size of the json.log files in your environment, run the following command:

   du -h `find /var/lib/docker/containers -name *-json.log*`

2. Stop the application and the database:

   /opt/bmc/stackmanager stop --deployment application
   /opt/bmc/stackmanager stop --deployment database
   

3. Stop the Docker service.

   systemctl stop docker

4. Go to the /etc/docker/daemon.json file and append the following entry:

   {
      "log-driver": "json-file",
      "log-opts":
      { "max-size": "20m", "max-file": "3" }
   }
5. Rename the /var/lib/docker/containers folder to create a backup folder.

6. Start the Docker service and verify whether all containers are displayed.

   systemctl start docker
   docker ps -a

   When you rename the folder, the registry container is removed. 

7. Run the registry container again after pointing to the correct dockerrepo folder on your system.

   docker run -d \  -p 5000:5000 \  --restart=always \  --name registry \  -v /opt/tsac_<version>/dockerrepo:/var/lib/registry \  registry:2
   

8. Verify whether the registry is set up correctly.

   curl http://localhost:5000/v2/_catalog

   Alternatively, you can use the browser to verify whether the registry is accessible by using the following URL: http://<TSAC-Docker-Host>:5000/v2/_catalog 

9. Start the database and then the application.

   /opt/bmc/stackmanager start --deployment database
   /opt/bmc/stackmanager start --deployment application
   
10. Log on to TrueSight Automation Console to continue using the product. 
    You can choose to remove the backup folder created in Step 5.
