尝试启动 carbon-cache 时出现 ValueError

Question

我对 Graphite 有疑问，特别是 carbon-cache。在某个时候，我让它运行了。现在几周后回来时，我试图再次开始使用石墨。 django-webapp 运行良好，但似乎我的 carbon-cache 后端有问题。 Graphite 安装在 /opt/graphite 中，我运行 /opt/graphite/bin/carbon-cache.py start。这是我得到的错误：

root@stfutm01:/opt/graphite/bin# ./carbon-cache.py start
Starting carbon-cache (instance a)
Traceback (most recent call last):

    archives = [ Archive.fromString(s) for s in retentions ]

    (secondsPerPoint, points) = whisper.parseRetentionDef(retentionDef)
  File "/usr/local/lib/python2.7/dist-packages/whisper.py", line 76, in parseRetentionDef
    (precision, points) = retentionDef.strip().split(':')
ValueError: need more than 1 value to unpack

我认为这是拆分 retentionDef.strip().split(':') 的问题。我的存储架构配置文件（/opt/graphite/conf/storage-schemas.conf）如下所示：

[stats]
priority = 110
pattern = ^stats\..*
retentions = 10s:6h,1m:7d,10m:1y
[ts3]
priority = 100
pattern = ^skarp\.ts3\..*
retentions = 60s:1y,1h,:5y

我应该在哪里寻找任何提示？或者有人知道我在这里缺少什么吗？

Answer 1

我认为问题在于 [ts3] 租用。 "The retentions line can specify multiple retentions. Each retention of frequency:history is separated by a comma."

在 ts3 中，它似乎是 3 次保留（以逗号分隔），第二次未指定历史记录，最后一次未指定频率。

retentions = 60s:1y,1h,:5y

我想你的意思可能是：

retentions = 60s:1y,1h:5y

这将是 1 年的 60 秒数据和 5 年后的 1 小时数据。
