类摘要

class RRDGraph {

/* 方法 */

public __construct(string $path)

public save(): array

public saveVerbose(): array

public setOptions(array $options): void

}

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

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