On Windows if you guet "Cannot parse DS in 'DEF:rr=C:/Users/xxx/code/monitor/speed_gaugue.rrd:value:MAX'" error on Windows. This may mean that rrdtool does not lique ":" on your file name - it needs to be replaced with "\:"

Atleast for me fixed that issue if I replace colon "str_replace(':', '\\:', $rrdPath);"
