Embedded version?

[lafar6502]

Hi, first of all, i'd like to thank the Author and all contributors for rrdtool, it's really a little software gem. I've been using it for many tasks and it's a solid, powerful and efficient tool (especially compared to various modern 'bigdata' time series databases that need half a datacenter to just run).
And my feature request is an embedded version, especially for ESP32 family of microcontrollers. Rrdtool would be a perfect tool to collect data and generate graphs directly at the microcontroller (and serve them via http), without needing additional servers or cloud infrastructure. I suppose these processors are powerful enough to handle the task. Realistic?

Sure, I expect this should be possible. Feel free to submit appropriate PRs.

Hi there,
I am a big fan of rrd and esp32.
I have been using this with good results.

Although there are limitations with the size.

note that this library is NOT a port of rrdtool to esp32 ... it only implements a vert simple buffer structure
