rrdtool

The rrdtool plugin updates a round robin database created by rrdtool with the message payload.

[config:rrdtool]
targets = {
    'living-temp'  : ['/tmp/living-temp.rrd',  '--template', 'temp'],
    'kitchen-temp' : ['/tmp/kitchen-temp.rrd', '--template', 'temp']
    }

rrdpython's API expects strings and/or list of strings as parameters to the functions. Thus a list for a target simply contains the command line arguments for rrdtool update. The plugin will embed the message as final argument N:<message>.

Requires the rrdtool bindings available with pip install rrdtool.
