Updating ${log_path:-} string in awi logback.xml file

Products

• CA Automic One Automation

Issue/Introduction

With the 21.0 Web Interface component, is it possible to change the path for logging?  For instance, is it supported to update:
<file>${log_path:-}${HOSTNAME}_${app_name:-ECC}_LOG.00.txt</file>
...
<fileNamePattern>${log_path:-}${HOSTNAME}_${app_name:-ECC}_LOG.0%i.txt</fileNamePattern>

to

<file>\tmp\logs\${HOSTNAME}_${app_name:-ECC}_LOG.00.txt</file>
...
<fileNamePattern>\tmp\logs\${HOSTNAME}_${app_name:-ECC}_LOG.0%i.txt</fileNamePattern>

some customers keep their log files in a specific folder that is not the default; for example:
/var/lib/tomcat/logs
/uc4files/

Environment

Release : 21.0

Component : AUTOMATION ENGINE

Resolution

With the jetty AWI in v21, the ${log_path:-} should not be changed in the logback.xml file.  

This is mentioned in the documentation as well: Important! Do not change any other parameters in this file. Changing other parameters might prevent CA Automic from investigating situations that cause errors.

For the Jetty AWI implementation in version 21, the ${log_path:-} variable is a hard coded log folder setting and does not allow for changes. 

The recommendation if another folder should be used is to use symbolic links to the WebInterface/osgi-tmp/0 directory.  

An enhancement request can also be created for being able to change this in future versions.
