Usage
sargraph2 [--type $GRAPH_TYPES] [--sa-file INFILE] [--output OUTFILE]
Examples
To plot CPU for today no arguments are needed:
sargraph2
To plot MEM for 20150330:
sargraph2 --type mem --sa-file /var/log/sysstat/sa20150330.gz
To plot I/O for 20150330 to a PNG file:
sargraph2 --type io --sa-file /var/log/sysstat/sa20150330.gz --output io.png
