Description

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, hygrometers, anemometers, light meters, DAQs, dataloggers, function generators, spectrum analyzers, power supplies, GPIB interfaces, and more.

The sigrok plugin is a fully fledged libsigrok client, and can use any supported hardware to feed measurements to collectd. Only analog sources are supported.

Hardware supported by libsigrok generally provides samples at much higher than 1Hz. The default output plugin in collectd, RRDtool, cannot deal with updates more than once per second, so the MinimumInterval keyword is recommended in this case.
