# By default, gather data from all data file system types.
# You can add many filesystems you want to include in the checks by just passing
# their names as argument on the script execution, you can either use filesystem
# or mount point. It admits regular expressions and it is case sensitive.
# You can also ignore certain checks by just using '-' and their name on execution.
#
# Sample usage: ./pandora_df_used -/DB /run$ /dev$

# Sample usage: ./pandora_df_used tmpfs /dev/sda1
