hbase - 为什么 OpenTSDB 选择 HBase 进行时序数据存储?

如果有人对选择 HBase 作为 OpenTSDB 的数据存储引擎有所了解,我将不胜感激?

还考虑了哪些其他选择,例如 Whisper(Graphite 前端 + Carbon 持久性)?

面向列的数据库(例如 HBase)如何成为时间序列数据的更好选择?

opentsdb - OpenTSDB 和单个测量中的多个值

据我了解,OpenTSDB 处理测量值是单个值的时间序列。许多测量设备在一次测量中提供一组值。例如,这可能是对一个设备的一次测量:2012-12-16 01:00:00, temp=12, current=2, waterheight=3, nacl-level0.5, ....

OpenTSDB 是否允许我将这些存储在一起,或者我是否被迫将它们存储为单独的时间序列?

opentsdb - OpenTSDB 过滤标签排除特定标签

是否可以查询所有可能的值但从搜索中排除特定值?

例如m=sum:rate:proc.stat.cpu{host=foo,type=*?!user},表示所有值,type但不包括user值。或类似的东西m=sum:rate:proc.stat.cpu{host=foo,type=*, type=!user}

hbase - OpenTSDB/HBase fails while uploading large amounts of data

I am new in Big Data and HBase, in participle. Now I am trying to use OpenTSDB to store data from sensors.

Configuration is: Cloudera vmware image with the last stable OpenTSDB installed on it. After configuring, I started server with

Then, I ran simple netcat client:

With ./run compiled from:

And afterwards watching for democ.%d metricas via localhost:4242.

I am satisfied with its performance, but there are problems when the generator produces a large number of metrics (n).

First problem is dissapearing of some datapoints. It depends of n. If n = 10000, there are 29 points in 30 seconds on the average. But if n = 75000, there are only 15 points. This problem is not critical. I think, it causes by disk bandwidth.

After some time, the server sends an error:

Second problem is HBase failure, after the server has been running for some time. OpenTSDB dies with massive flooding to all clients and own console with such message:

What can I do to solve this problem?

I also thought about the possibility of using Cassandra for my project.

What the best opensource solution to store time series data (approximately, I need to store data from 100 000 sensors for 30 days, while each sensor generates up to 40 bytes of data every second).

我已按照说明成功安装了 Cloudera 4 节点 Hadoop 集群,其中包含 HBase 等所有软件。

然后安装并构建 asynchbase,然后是 OpenTSDB。似乎奏效了。但是,当我尝试按照他们的网站“入门指南”运行它时,会输出此错误。有什么提示吗?谢谢你。

opentsdb - 将 csv 数据导入 OpenTSDB

我已经在 Cloudera Hadoop/HBase 集群上成功安装了 OpenTSDB。

我的问题是,我有大量的 1 分钟历史股票数据,如下所示:

......

从 QS 指南中的文档中,它在批量导入部分中说:

./tsdb 导入你的文件

当我在我的数据上尝试这个时,它会抛出一个无用的异常。

关于如何将其导入 OpenTSDB 的任何提示?谢谢。

javascript - 了解 OpenTSDB 时间戳

我想为 OpenTSDB 创建一个非常简单的收集器,例如,我正在考虑创建一个简单的 javascript 文件来写入一些随机值。

我不明白的是那些随机值的格式。例如,我必须编写一个写入字符串的程序metric.name timestamp value,或者我的简单程序只写入一个值就足够了?
