石墨返回不正确的数据点 [英] Graphite returning incorrect datapoint

问题描述

• 我下载了statsd和石墨0.9.x
• 我使用了statsd源提供的stats-client，如下所示:
  • ./statsd-client.sh 'development.com.alpha.operation.testing.rate:1|c'
  • I downloaded statsd and graphite 0.9.x
  • I used the stats-client provided with source of statsd as follows:
    • ./statsd-client.sh 'development.com.alpha.operation.testing.rate:1|c'

    然后我尝试查询最近24小时的摘要:

    Then I tried querying for a summary for last 24 hours:

    http://example.com/render?format=json&target=summarize(stats.development.com.alpha.operation.testing.rate ， "24hours"，"sum"，true)& from = -24hours& tz = UTC

    http://example.com/render?format=json&target=summarize(stats.development.com.alpha.operation.testing.rate, "24hours", "sum",true)&from=-24hours&tz=UTC

    我得到1个数据点，如下所示:

    I get 1 datapoint as follows:

    "datapoints": [[0.0, 1386277560]]}]
    

    为什么我得到0.0?甚至Graphite Composer也不显示任何内容

    Why I am getting 0.0? Even Graphite Composer does not display anything

    当我执行10次操作时，我期望的值为"10".我做错了什么?

    I was expecting a value of "10" as I performed the operation 10 times. What did I do wrong?

    storage-schemas.conf

    [carbon]
    pattern = ^carbon\.
    retentions = 60:90d
    
    [default_1min_for_1day]
    pattern = .*
    retentions = 60s:1d
    

    请帮助我理解问题.

    根据以下答案，我更改了存储聚合，并在metric_file.wsp上运行whisper-info后得到以下响应.但是我仍然在数据点中获得"0.0"作为值，并且Graphite浏览器不显示任何内容.

    As per answer below, I changed storage-aggregation and I get following response after running whisper-info on metric_file.wsp. But I am still getting "0.0" as value in datapoint and Graphite browser does not display anything.

    maxRetention: 86400
    xFilesFactor: 0.0
    aggregationMethod: sum
    fileSize: 17308
    
    Archive 0
    retention: 86400
    secondsPerPoint: 60
    points: 1440
    size: 17280
    offset: 28
    

    我还根据另一个答案中的建议查看了stats_counts树，但相同.

    I also looked at stats_counts Tree as suggested in another answer, but its the same.

    我的设置有什么问题.除了以下存储聚合中的答案所建议的更改以外，我对所有内容都使用默认设置

    What is wrong with my setup. I am using default setting for everything but the changes suggested by an answer below in storage-aggregation

    推荐答案

    在Whisper软件包中，您将获得一个脚本whisper-info.py.在适当的指标文件上调用它-

    Within the whisper package, you will get a script- whisper-info.py. Invoke it on the appropriate metric file-

    /whisper-info.py /opt/graphite/storage/whisper/alpha/beta/charlie.wsp

    您将获得类似这样的内容

    You will get something like this-

    maxRetention: 31536000
    xFilesFactor: 0.0
    aggregationMethod: sum
    fileSize: 1261468
    
    Archive 0
    retention: 31536000
    secondsPerPoint: 300
    points: 105120
    size: 1261440
    offset: 28
    

    在这里，请确保aggregationMethod为和，而xFilesFactor为0.0.很有可能不是，因为这不是石墨的默认行为.现在创建一个正则表达式来获取您的指标并将其放在配置文件storage-aggregation.conf的开头.这将确保新创建的指标遵循此新的聚合规则.您可以在此处详细了解xFilesFactor的工作原理.

    Here, make sure that aggregationMethod is sum, and xFilesFactor is 0.0. Most probably it is not, since this isn't graphite's default behavior. Now make a regex that picks up your metrics and put it at the beginning of the config file storage-aggregation.conf. This will ensure that the newly created metrics follow this new aggregation rule.
