Since Logscape is running on most of your hosts, why not use it to clean up directories as and when they need it.
The two main use cases so far:
1. Cleanining .hprof dump files from Java application folders
2. Removing common data files from a central repository
3. Removing old libraries from directories
It's fairly simple, you simply have a .properties file in the lib folder which contains JSON strings, the parameters of which then determine what is deleted and when. An example below:
In this example, the TESTNICK directory and all subdirectories will be cleaned of any file labelled .hprof that goes 60 minutes without being modified. However, the TESTNICK2 directory will be cleaned of all filenames including a . once they go 24 hours without being modified. the folder TESTNICK2/SAFE however would remain untouched.
