手把手教你如何使用 Timestream 实现物联网时序数据存储和分析

Amazon Timestream 是一种快速、可扩展的无服务器时间序列数据库服务，适用于物联网和运营应用程序，使用该服务每天可以轻松存储和分析数万亿个事件，速度提高了 1000 倍，而成本仅为关系数据库的十分之一。通过将近期数据保留在内存中，并根据用户定义的策略将历史数据移至成本优化的存储层，Amazon Timestream 为客户节省了管理时间序列数据生命周期的时间和成本。Amazon Timestream 专门构建的查询引擎可用于访问和分析近期数据和历史数据，而无需在查询中显式指定数据是保存在内存中还是成本优化层中。Amazon Timestream 内置了时间序列分析函数，可以实现近乎实时地识别数据的趋势和模式。Amazon Timestream 是无服务器服务，可自动缩放以调整容量和性能，因此无需管理底层基础设施，可以专注于构建应用程序。

本文介绍通过 Timestream、Kinesis Stream 托管服务和 Grafana 和 Flink Connector 开源软件实现物联网（以 PM 2.5场景为示例）时序数据实时采集、存储和分析，其中包含部署架构、环境部署、数据采集、数据存储和分析，希望当您有类似物联网时序数据存储和分析需求的时候，能从中获得启发，助力业务发展。

架构

Amazon Timestream 能够使用内置的分析函数（如平滑、近似和插值）快速分析物联网应用程序生成的时间序列数据。例如，智能家居设备制造商可以使用 Amazon Timestream 从设备传感器收集运动或温度数据，进行插值以识别没有运动的时间范围，并提醒消费者采取措施（例如减少热量）以节约能源。

本文物联网（以PM 2.5场景为示例），实现 PM2.5数据实时采集、时序数据存储和实时分析，其中架构主要分成三大部分：

实时时序数据采集：通过Python数据采集程序结合Kinesis Stream和Kinesis Data Analytics for Apache Flink connector 模拟实现从PM 2.5监控设备, 将数据实时采集数据到Timestream。
时序数据存储：通过Amazon Timestream时序数据库实现时序数据存储，设定内存和磁性存储（成本优化层）存储时长，可以实现近期数据保留在内存中，并根据用户定义的策略将历史数据移至成本优化的存储层。
实时时序数据分析：通过Grafana （安装Timesteam For Grafana插件）实时访问Timestream数据，通过Grafana丰富的分析图表形式，结合Amazon Timestream 内置的时间序列分析函数，可以实现近乎实时地识别物联网数据的趋势和模式。

具体的架构图如下：

部署环境

1.1 创建 Cloudformation

请使用自己帐号 (region 请选择 us-east-1)

下载 Github 上 Cloudformation Yaml 文件：

git clone https://github.com/bingbingliu18/Timestream-pm25

Timestream-pm25目录中包含下面 Cloudformation 所用文件 timestream-short-new.yaml

其它都选择缺省，点击 Create Stack button.

Cloud Formation 创建成功

1.2 连接到新建的 Ec2 堡垒机:

修改证书文件权限

chmod 0600 [path to downloaded .pem file]

ssh -i [path to downloaded .pem file] ec2-user@[bastionEndpoint]

执行 Amazon configure：

Amazon configure

default region name, 输入： “us-east-1”，其它选择缺省设置。

1.3 连接到 EC2堡垒机安装相应软件

设置时区

TZ='Asia/Shanghai'; export TZ

Install python3

sudo yum install -y python3

Install python3 pip

sudo yum install -y python3-pip

pip3 install boto3

sudo pip3 install boto3

pip3 install numpy

sudo pip3 install numpy

install git

sudo yum install -y git

1.4 下载 Github Timesteram Sample 程序库

git clone https://github.com/awslabs/amazon-timestream-tools amazon-timestream-tools

1.5 安装 Grafana Server

连接到 EC2堡垒机：

sudo vi /etc/yum.repos.d/grafana.repo

For OSS releases:(拷贝以下内容到grafana.repo)

[grafana]

name=grafana

baseurl=https://packages.grafana.com/oss/rpm

repo_gpgcheck=1

enabled=1

gpgcheck=1

gpgkey=https://packages.grafana.com/gpg.key

sslverify=1

sslcacert=/etc/pki/tls/certs/ca-bundle.crt

安装 grafana server:

sudo yum install -y grafana

启动 grafana server:

sudo service grafana-server start
sudo service grafana-server status

配置 grafana server 在操作系统启动时自动启动:

sudo /sbin/chkconfig --add grafana-server

1.6 安装 timestream Plugin

sudo grafana-cli plugins install grafana-timestream-datasource

重启 grafana

sudo service grafana-server restart

1.7 配置 Grafana 要访问 Timesteam 服务所用的 IAM Role

获取 IAM Role Name

选择 IAM 服务，选择要修改的 role, role name:

timestream-iot-grafanaEC2rolelabview-us-east-1

修改 role trust relationship:

将 Policy document 全部选中，替换成以下内容：

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Sid":"",
      "Effect": "Allow",
      "Principal": {
        "Service": "ec2.amazonaws.com"
      },
      "Action": "sts:AssumeRole"
    },
    {
      "Sid":"",
      "Effect": "Allow",
      "Principal": {
        "AWS": "[请替换成CloudFormation output中的role arn]"
      },
      "Action": "sts:AssumeRole"
    } 
  ]
}

修改后的 trust relationship:

1.8登录到 Grafana server

第一次登录到 Grafana Server:

打开浏览器访问 http://[Grafana server public ip]:3000
缺省的 Grafana Server 监听端口是： 3000 .

如何获取 Ec2 Public IP 地址，如下图所示，访问 Cloudformation output：

在登陆界面, 输入 username: admin; password:admin.(输入用户名和密码都是 admin)
点击 Log In.登陆成功后，会收到提示修改密码

1.9 Grafana server 中增加 Timestream 数据源

增加 Timestream 数据源

1.10 Grafana server 中配置 Timestream 数据源

拷贝配置所需要 role ARN 信息（从 cloudformation output tab）Default Region: us-east-1

IoT 数据存储

2.1 创建 Timestream 数据库 iot

2.2 创建 Timestream 表 pm25

IoT 数据导入

3.1安装 Flink connector to Timestream

安装java8

sudo yum install -y java-1.8.0-openjdk*

java -version

安装debug info, otherwise jmap will throw exception

sudo yum --enablerepo='*-debug*' install -y java-1.8.0-openjdk-debuginfo

Install maven

sudo wget https://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo 
sudo sed -i s/$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo 
sudo yum install -y apache-maven 
mvn --version

change java version from 1.7 to 1.8

sudo update-alternatives --config java

sudo update-alternatives --config javac

安装 Apache Flink

最新的 Apache Flink 版本支持 Kinesis Data Analytics 是1.8.2.

Create flink folder

cd

mkdir flink

cd flink

下载 Apache Flink version 1.8.2 源代码:

wget https://archive.apache.org/dist/flink/flink-1.8.2/flink-1.8.2-src.tgz

解压 Apache Flink 源代码:

tar -xvf flink-1.8.2-src.tgz

进入到 Apache Flink 源代码目录:

cd flink-1.8.2

Compile and install Apache Flink (这个编译时间比较长需要大致20分钟):

mvn clean install -Pinclude-kinesis -DskipTests

3.2 创建 Kinesis Data Stream Timestreampm25Stream

aws kinesis create-stream --stream-name Timestreampm25Stream --shard-count 1

3.3 运行 Flink Connector 建立 Kinesis 连接到 Timestream:

cd
cd amazon-timestream-tools/integrations/flink_connector
mvn clean compile

数据采集过程中请持续运行以下命令：

mvn exec:java -Dexec.mainClass="com.amazonaws.services.kinesisanalytics.StreamingJob" -Dexec.args="--InputStreamName Timestreampm25Stream --Region us-east-1 --TimestreamDbName iot --TimestreamTableName pm25"

3.4 准备 PM2.5演示数据:

mkdir pm25

cd pm25

下载 Github 上数据采集 Python 程序：

git clone https://github.com/bingbingliu18/Timestream-pm25

cd Timestream-pm25

运行5演示数据生成程序 (python 程序2个参数 –region default: us-east-1; –stream default: Timestreampm25Stream)

数据采集过程中请持续运行以下命令：

python3 pm25_new_kinisis_test.py
