ArcGIS for Server 10.3 is creating a \arcgisserver\directories folder on our C: drive even though all our ArcGIS for Server Directories are set to the 😧 drive. If I delete it I find that it reappears in a few seconds. When I first installed 10.3 the \arcgisserver\directories\arcgissystem\statistics folder was in the C: drive. I also noticed that when I started the Search service the \arcgisserver\directories\arcgisjobs\utilities\search_indexer_gpserver was created in the C: drive. I have changed Server Directories back and forth, rebooted, and searched registry and directory for "C:\arcgisserver" but was still unable to resolve the issue.
That occurred to me too but that is a different issue from the original question.
Agreed. I'll post it up...
Just a quick update-
To manage the statistics, see the following help section 'Configure server statistics' at:
Working with server statistics—Documentation | ArcGIS for Server
There is a new usagereports resource accessed from the server admin directory that allows you to specify the compile period for statistics and how long to keep statistics. The defaults are 30 min and forever, respectively.
