33 Usage plotfs.cgi: system=<system> filesytem=<filesystem>
34 [height=<height>] [width=<width>] [color=<color>]
35 [scaling=<scaling>] [points=<points>] [tiny=<0|1>]
38 <system>: Name of the system defined in the Clearadm database to
39 retrieve filesystem snapshots for.
40 <filesystem>: Name of the filesytem to plot information for
41 <height>: Height of chart (Default: 480px - tiny: 40)
42 <width>: Width of chart (Default: 800px - tiny: 150)
43 <color>: A GD::Color color value (Default: lblue)
44 <scaling>: Currently one of Minute, Hour, Day or Month. Specifies how
45 Clearadm::GetFS will scale the data returned (Default: Minute
47 <points>: Number of points to plot (Default: all points - tiny: 7)
51 Draws a chart of the filesystem usage for the system and filesystem passed in.
52 Parameters such as height, width, color, scaling and points can be set
53 individually though more often the user will just use the web controls to set
54 them. Defaults produce a nice chart. Tiny mode is used by systemdetails.cgi to
55 draw tiny charts in the table. Setting tiny sets a number of the other chart
56 options to produce a standard, tiny chart.
