python – Graphite：帮我解释一下whisper-info.py输出

2019年8月4日 243次阅读

我一直试图从whisper-info.py输出中弄清楚它对我来说似乎有点神秘.

目前这是我的设置：

存储schema.conf的

[carbon]
pattern = ^carbon\.
retentions = 60:90d

[stats]
pattern = ^stats.*
retentions = 30s:6h,1min:30d,10min:360d,30min:720d,1h:1825d,1d:1825d

[everything_else]
pattern = .*
retentions = 30s:6h,1min:30d,10min:360d,30min:720d,1h:1825d,1d:1825d

存储aggregation.conf

[min]
pattern = \.lower$
xFilesFactor = 0.1
aggregationMethod = min

[max]
pattern = \.upper(_\d+)?$
xFilesFactor = 0.1
aggregationMethod = max

[sum]
pattern = \.sum$
xFilesFactor = 0
aggregationMethod = sum

[count]
pattern = \.count$
xFilesFactor = 0
aggregationMethod = sum

[count_legacy]
pattern = ^stats_counts.*
xFilesFactor = 0
aggregationMethod = sum

[default_average]
pattern = .*
xFilesFactor = 0.3
aggregationMethod = average

我在它面前有统计数据,非常小
localConfig.js

{
graphitePort: 2003,
graphiteHost: "127.0.0.1",
port: 8125,
flushInterval: 30000,
}

现在我发送一个数据包到stasd到一个全新的指标

echo "alex.foo:1|c" | nc -w1 -u 127.0.0.1 8125

这是whisper-info.py的输出：

# whisper-info.py /opt/graphite/storage/whisper/stats/alex/foo.wsp 
maxRetention: 604800
xFilesFactor: 0.300000011921
aggregationMethod: average
fileSize: 120988

Archive 0
retention: 604800
secondsPerPoint: 60
points: 10080
size: 120960
offset: 28

当我明显有更多的保留设置时,为什么只有一个档案？我的架构规则不正确吗？输出是什么意思？是文件大小的大小？偏移？

感谢您抽出宝贵时间回答！

最佳答案 我发现问题与我的storage-schema.conf文件的语法有关.我找到了这个方便的工具validate-storage-schemas.py(在/ opt / graphite / bin /中找到),输出非常清楚.

./validate-storage-schemas.py 
Loading storage-schemas configuration from default location at: '/opt/graphite/conf/storage-schemas.conf'
Section 'carbon':
  OK
Section 'stats':
  - Error: Section 'stats' contains an invalid retention definition ('30s:6h,1min:30d,10min:360d,30min:720d,1h:1825d,1d:1825d')
    Lower precision archives must cover larger time intervals than higher precision archives (archive4: 157680000 seconds, archive5: 157680000 seconds)
  OK
Section 'everything_else':
  - Error: Section 'everything_else' contains an invalid retention definition ('30s:6h,1min:30d,10min:360d,30min:720d,1h:1825d,1d:1825d')
    Lower precision archives must cover larger time intervals than higher precision archives (archive4: 157680000 seconds, archive5: 157680000 seconds)
  OK

现在如果我对他们有意义的文件做一个耳语信息：

root @ graftwo：/ opt / graphite#whisper-info.py /opt/graphite/storage/whisper/local/test/diceroll.wsp
    maxRetention：172800000
    xFilesFactor：0.300000011921

Archive 5
retention: 172800000
secondsPerPoint: 86400
points: 2000
size: 24000
offset: 2089528

我仍然想知道两件事：
– 为什么碳复制失败并且语法不正确？
– 这个严格的默认值来自哪里？
– 这个偏移的东西是什么？

谢谢！希望这有助于其他人
