 Checks for amount of files within a directory depending on the set filters
 
-Invoke-IcingaCheckDirectory will check within a specific directory for files matching the set filter criteria.
-It allows to filter for files with a specific size, modification date, name or file ending.
-By using the Warning or Critical threshold you can then set on when the check will be set to 'WARNING' or 'CRITICAL'.
-
-Based on the provided filters, the plugin will return the amount of files found matching those filters.
