This section completely reproduces the df(1) utility. For each mounted
filesystem it reports the number of total and available blocks (for
both superuser and user), and usage in percents.
In addition it reports about available and used file inodes in numbers
and percents.
This section has a capability of visual alert which is being triggered
when either some filesystem becomes more than 90% full or there are
less than 10% of free file inodes left. When this event happens the
filesystem related report row will be displayed in the bold font and
in the red color.
If you don't want the df(1) section to be displayed set:
$Apache::VMonitor::Config{fs_usage} = 0;
The default is to display this section.
