Subject: [PATCH] sadf: Don't cap SVG graph output at 100% (#388)
|
||||
|
||||
Don't cap SVG graph output at 100% when values greater than 100% are
|
||||
possible. Such a possibility exists for overcommited memory (displayed
|
||||
as %commit with "sar -r").
|
||||
|
||||
Note: I don't think such other metrics exist. Tell me if I'm wrong.
