RRDBar: RRD summary tool
The RRDBar CGI script generates a graphic that shows the current
status of a given data source in a RRD Database. This is intended to be used
to show a compact summary of the current state of a monitored
resource.
This is built using Tobias Oetiker's RRDTool database tool. It only reports
on the data, it does not gather it.
Examples
A single data source shown as a single bar, with a label
Params: RRD=data.rrd DS=dsone MAX=100
Multiple data sources shown as grouped bars, with labels
Params: RRD=data.rrd DS='dsone dstwo dsthree' MAX=100
Multiple data sources shown as stacked bars, with labels
Params: RRD=data.rrd DS='dsone @dstwo @dsthree' MAX=100
Multiple data sources shown as lines
Params: RRD=data.rrd DS='-dsone -dstwo -dsthree' MAX=100 LAB=0
Two data sources, one as a bar, one as a line, with labels
Params: RRD=router.rrd MAX=8000 LAB=2
