Advanced Log Stream Properties
You can use the following advanced properties to customize the run-time behavior of the log stream service.
Apply advanced settings to the log stream by updating the appVersion=v2 properties in the linkpro-app.properties file. If the linkpro-app.properties file is not present at the specified location, create the file manually.
