如何最少地计算石墨图
require 'statsd' statsd = Statsd.new('localhost', 8125).tap{|sd| sd.namespace = 'account'} 1.times do statsd.increment 'hitcount4' end sleep 5 5.times do statsd.increment 'hitcount4' end sleep 10 10.times do statsd.increment 'hitcount4' end 我正在使用ruby gem statsd-ruby
我运行上面的脚本它成功执行，图形出现但我只能看到x轴上的一条线而没有（没有y轴的值），如何获取上述脚本的图形？
我想记录每个增量调用。
/opt/graphite/statsd/local.js的内容

/opt/graphite/conf/storage-schemas.conf的内容
[carbon] pattern = ^carbon\. retentions = 60:90d [stats] pattern = ^stats.* retentions = 1s:6h,10min:10d,10min:5y [rtpg] pattern = ^rtpg.* retentions = 1s:7d,10s:21d,60s:5y
/opt/graphite/conf/storage-aggregation.conf的内容
[rtpg] pattern = .* xFilesFactor = 0 aggregationMethod = sum [sum] pattern = \.count$ xFilesFactor = 0 aggregationMethod = sum
用，
本地主机：8090 /渲染目标= rtpg.testing_server_2.counters.account.hitcount4.count＆格式=原始？

我将flush intervel（statsd）更新为6000，并进行了更新
/opt/graphite/conf/storage-schemas.conf
[carbon] pattern = ^carbon\. retentions = 60:90d [rtpg] pattern = ^rtpg.* retentions = 1m:6h,1m:7d,10m:5y
并在我的脚本中运行了whisper-resize.py并将计数器名称更新为’hitcount6’并再次运行脚本，创建了一个新图表，问题仍然存在，实际上我想要的是石墨显示精确计数，如第一个增量，然后睡眠5分钟，然后5个增量等等，我不想平均我的数据，最后我将创建一个xml报告，调用增量方法的次数。 $ whisper-info.py /opt/graphite/storage/whisper/rtpg/testing_server_2/counters/account/hitcount6/count.wsp
maxRetention: 604800 xFilesFactor: 0.0 aggregationMethod: sum fileSize: 120988 Archive 0 retention: 604800 secondsPerPoint: 60 points: 10080 size: 120960 offset: 28
长话短说：当使用Graphite作为后端时， 不能以低于1秒的间隔刷新Statsd 。
因为你已经指定了10毫秒的flushInterval，StatsD将每隔10毫秒刷新一次聚合数据点，其中Graphite将从100个中删除99个（除了10毫秒之一之外的所有刷新）。
首先 ，将其设置为低，会破坏Statsd的一些目的，因为它旨在充当可以减少石墨负载的聚合器。 其次 ，将其设置为低于1秒的任何值都将导致公制数据丢失。 这是因为您可以在Graphite中存储的最精确度是1秒。 因此，您每秒会向石墨发送100个数据点，而Graphite只会存储1个。 您必须非常幸运地看到任何数据（因为它将占用间隔的最后一个指标（覆盖其他指标）。
您必须将StatsD中的刷新间隔与Graphite中的最精确架构设置 （在存储架构配置中）相匹配 。 您可以使用的最低值为1秒，但建议使用10秒，以便StatsD可以代表您执行一些重要的聚合工作。
我建议你将最好的（第一）精度更改为10秒 ，即10s:6h和10s:7d用于保留（以及Statsd flushInterval到10000 ms），以便Statsd和Graphite很好地排列。
接下来 ，进行上述更改，然后调整耳语文件的大小以确保已进行设置。 也许您在存储指标后（在whisper = graphite的存储中）更改了石墨架构或聚合设置，您仍然需要删除指标的.wsp文件（graphite会重新创建它们）或运行whisper-resize.py 。 耳语文件是/graphite/storage/whisper/ 。
最后 ， validation设置 。 您可以通过在.wsp文件上运行whisper-info.py来针对某些私语数据validation设置。 在/ graphite / storage / whisper / Run： whisper-info.py my_metric_data.wsp找到您的某个指标的.wsp文件。 whisper-info.py输出应该告诉您有关存储设置如何工作的更多信息。
