# Debug Values
# 1 - print interesting stuff
# 2 - print more instersting stuff
# 4 - do NOT start collectl. real handy for debugging collectl side
# 8 - replaced functionality with -noescape
# 16 - show selected hostname/addresses and exit
# 32 - echo chars received on STDIN
# 64 - echo comments from collectl. useful when inserting debugging comments
# 128 - echo everything from collectl
# 256 - async double-buffering
# 512 - echo collectl version checking commands
# KNOWN PROBLEMS
#
# pdsh format is not handled correctly by csh and you will need to quote expressions
#
# The format of the process data may vary based on whether or not a system provides
# I/O stats as well. If not all systems provide a consistent format, you will get
# some unaligned columns, the headers based on the first system configuration.
#
# Lustre FS and OST names can vary in width so if you're monitoring systems with
# different name widths the columns won't line up. However, since one typically
# wouldn't monitor mixed lustre environments at the same time, they should all be
# consistent in width, unlike netnames whose widths do and you may need to
# include --netopts w in your collectl command
#
# colmux will sort columns as numeric or string. Numeric preserves sort order whereas
# string sorts will go by the leftmost digits, giving 10 a higher sort order than 9.
# If colmux sees a column that does contain a digit it will do a string sort. This
# will affect any number fields, eg process priorities can also be RT
