what is reporting "total CPU usage" and what metric is it based on.

Many "reporters" are not virtualization savvy and report high% usage when physical usage is actually near idle.

No real advice possible without knowing where the complaint is coming from, etc..

NAME
memusagestat - generate graphic from memory profiling data SYNOPSIS
memusagestat [option]... datafile [outfile] DESCRIPTION
memusagestat creates a PNG file containing a graphical representation of the memory profiling data in the file datafile; that file is gen- erated via the -d (or --data) option of memusage(1). The red line in the graph shows the heap usage (allocated memory) and the green line shows the stack usage. The x-scale is either the num- ber of memory-handling function calls or (if the -t option is specified) time. OPTIONS
-o file, --output=file Name of the output file. -s string, --string=string Use string as the title inside the output graph. -t, --time Use time (rather than number of function calls) as the scale for the X axis. -T, --total Also draw a graph of total memory consumption. -x size, --x-size=size Make the output graph size pixels wide. -y size, --y-size=size Make the output graph size pixels high. -?, --help Print a help message and exit. --usage Print a short usage message and exit. -V, --version Print version information and exit.
