This really speaks to me - rrdtool is criminally underutilized. Great work! I did something different but in a similar vein for one server network. We had Seq already deployed for log monitoring so instead of setting up a separate network/node/app health monitoring interface I configured everything to regularly ping seq with a structured log message containing the needed data that could be extracted and graphed with seq’s limited oob charting abilities in the dashboard. Not perfect, but simpler.
