石墨支持https://graphite.readthedocs.io/en/1.1.2/functions.html#graphite.render.functions.reduceSeries 例如,
reduceSeries(mapSeries(servers.*.disk.*,1),"asPercent",3,"bytes_used","total_bytes")
这对我有用。 mapSeries的输入可以是其他函数的返回值吗?例如
reduceSeries(mapSeries(aliasSub(keepLastValue(servers.*.disk.*), 'keepLastValue\((.+)\)', '\1.value'), "derivative", 4, "value")
但这不起作用。可以吗?
