I'm responding to a very old post here; hopefully someone will see this.
We need to be able to track these logs using a log-aggregator, in our case 'splunk'. It will be simple enough to add the 'splunk' user to the arcgis group. But the arcgis directories are stored with 700 permissions, and the log files with 600 permissions.
We want to use 750 and 640 permissions, so that a member of the same GROUP can read the files.
How can we override the umask associated with the creation of these log files and their parent directories?
