使用statsd的好处？

Question

在过去的几天里，我一直在玩石墨，我可以看到石墨的潜力，以及它为什么如此强大。

我的主要问题是，为什么我应该像esty和其他很多人那样在前面使用statsd？到目前为止，我还没有看到把另一堆放在石墨前面有什么好处。

我希望有人能把它弄清楚

所以我进入了IRC频道

<jY> what are the benefits of putting statsd in front of graphite
 <vvuksan> data aggregation
 <vvuksan> say you wanted to find out how many registrations you have per time period
 <vvuksan> you can either keep track of it yourself
 <vvuksan> send to graphite every minute
 <vvuksan> or
 <vvuksan> any time there is a successful registration send a packet to statsd and let statsd deal with it
 <jY> ok.. so i  just keep incing the counter then to statsd?
 <vvuksan> no
 <vvuksan> you just send to statsd
 <vvuksan> statsd will increment it for you
 <jY> ok
 <vvuksan> you can do all this yourself
 <vvuksan> it's just more work
 <jY> could i also send stuff like load avg to statsd.. or should that go right to graphite?
 <vvuksan> that should go right to graphite
 <vvuksan> cause that is already a composite metric
 <vvuksan> not just a data point
 <jY> ok so it's really only app specific stuff 
 <jY> ok thanks.. clears up a lot
 <jY> statsd would be good to send logins to.. so i can see how many logins per minute i get in other words
 <vvuksan> yeah
 <vvuksan> or what's average response time of an external API
 <vvuksan> it will also do percentiles which is useful
 <vvuksan> you could even do how long it took to execute a particular important query
 <jY> great.. thanks that cleared up a lot

因此，我的方法是发送系统统计数据，如空闲内存/驱动器空间/用户登录到石墨，并发送应用程序统计数据，比如用户登录到statsd，并让statsd发挥其神奇的作用，为石墨生成良好的图形数据。
