my $DISK_CRIT_THRESHOLD = 90;
my $DISK_WARN_THRESHOLD = 80;

my $DISK_CRIT_THRESHOLD = 90;

my $DISK_WARN_THRESHOLD = 80;

Change them as desired to give different warning/critical levels.

In one case that we worked on, the server had multiple partitions. We wanted different thresholds on each partition which was accomplished with the following patch:
