Log file size is 0

Issue

Why the other log files size is 0. The files are "host-manager.xxxx-xx-xx.log, localhost.xxxx-xx-xx.log, manager.xxxx-xx-xx.log".

Environment

Liferay DXP 7.2

Resolution

The other log files "host-manager.xxxx-xx-xx.log, localhost.xxxx-xx-xx.log, manager.xxxx-xx-xx.log" will be 0 in size until unless those have been configured through logging.properties.

Detailed information about the same is described in this blog "Liferay and Tomcat logging". Please have a look at it for the complete reference.
Below is the example from the unofficial thread "difference between localhost.log, catalina.log, manager.log, host-manager.log".
- localhost_access (only one defined in server.xml) the access log (= all requests like in httpd),
- localhost the log of the host and finally
- host-manager and manager the logs of the related web applications.
Here a commented example to try help you read logging.properties:
```
# log on the host "localhost"
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].xxx
# log on the host "localhost" for the webapp foo
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/foo].xxx
```
More generally the pattern is:
```
org.apache.catalina.core.ContainerBase.[${engine}].[${host}].[${context}]
```
