     <B>Top section</B>

       Represents the emulation of top utility, while individually
       reporting only on httpd processes, and provides information
       specific to these processes.

       <B>1st</B>: current date/time, uptime, load average: last 1, 5 and 15
       minutes, total number of processes and how many are in the
       running state.

       <B>2nd</B>: CPU utilization in percents: by processes in user, nice,
       sys and idle state

       <B>3rd</B>: RAM utilization: total available, total used, free, shared
       and buffered

       <B>4th</B>: SWAP utilization: total available, total used, free, how
       many paged in and out
     },

Reports the utilization of all mounted filesystems:

<B>FS</B>  = the mount point of filesystem<BR>

<B>Blocks (1k)</B> = Space usage in blocks of 1k bytes<BR>

<B>Total</B>  = Total existing<BR>
<B>SU Avail</B> = Available to superuser (root) (tells how much space let for real)<BR>
<B>User Avail</B> = Available to user (non-root) (user cannot use last 5% of each filesystem)

<B>Usage</B> = utilization in percents (from user perspective, when it reaches
100%, there are still 5% but only for root processes)

<B>Files</B>: = File nodes usage<BR>
<B>Total</B>   = Total nodes possible <BR>
<B>Avail</B> = Free nodes<BR>
<B>Usage</B> = utilization in percents<BR>

If you want the mount(1) section to be displayed set:

  $Apache::VMonitor::Config{mount} = 1;

The default is NOT to display this section.

=item df(1) emulation 

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;
