石墨:每点时间精度 [英] Graphite: time per point precision

问题描述

是否可以以毫秒为单位存储每个点的时间?

Is it possibile to store time per point with millisecond precision?

由于石墨基于

Since Graphite is based on Whisper I've took a look at whisper.py file. It contains:

UnitMultipliers = {
   's' : 1,
   'm' : 60,
   'h' : 60 * 60,
   'd' : 60 * 60 * 24,
   'y' : 60 * 60 * 24 * 365,
}

因此似乎可以以最大1s的精度记录事件. 我该如何应对每10毫秒产生一次事件的系统?

so it seems that it's possibile to record events with a maximum precision of 1s. How can I cope with a system that produces an event every 10ms?

推荐答案

您可以将数据发送到Carbon-aggregator守护程序或Statsd.它们都是聚合器，因此它们聚合了毫秒数据并以每秒的值将其写出.对于碳聚合器，您必须使用希望的数据收集方式配置聚合器:求和，平均等.对于Statsd，api调用确定所使用的聚合，因此您不必预先配置它.

You can send the data to the carbon-aggregator daemon or Statsd. These are both aggregators, so they'd aggregate the millisecond data and write it out in a per second value. For carbon-aggregator, you'd have to config the aggregator with how you want the data gathered: sum, avg, etc. For Statsd, the api call determines the aggregation used, so you don't have to pre-configure it.
