Check Path Age

Project Notes

-- Check the age of an individual file
**** Example: Monitor the age of a log file to ensure it is being written to on a regular basis.

-- Check the age of the newest file in a directory
**** Example: Monitor the age of a backup folder to ensure that nightly backups are getting created and are no older than 24 hours.

-- Check the age of the oldest file in a directory
**** Example: Monitor the age of a "queue" directory to ensure that the oldest "job" in the queue is no older than a specified limit.

-- Check the age of a non-existent file or directory
**** Example: Monitor the age of error log that only exists if errors are present.

-- Recursively check the age of all files in a directory and its sub-directories
