Usage

sargraph2 [--type $GRAPH_TYPES] [--sa-file INFILE] [--output OUTFILE]
33+
34+
Examples
35+
36+
To plot CPU for today no arguments are needed:
37+
sargraph2
38+
To plot MEM for 20150330:
39+
sargraph2 --type mem --sa-file /var/log/sa/sa20150330.gz
40+
To plot I/O for 20150330 to a PNG file:
41+
sargraph2 --type mem --sa-file /var/log/sa/sa20150330.gz --output io.png
