Amazon Timestream 是一種快速、可擴充套件的無伺服器時間序列資料庫服務,適用於物聯網和運營應用程式,使用該服務每天可以輕鬆儲存和分析數萬億個事件,速度提高了 1000 倍,而成本僅為關聯式資料庫的十分之一。通過將近期資料保留在記憶體中,並根據使用者定義的策略將歷史資料移至成本優化的儲存層,Amazon Timestream 為客戶節省了管理時間序列資料生命週期的時間和成本。Amazon Timestream 專門構建的查詢引擎可用於訪問和分析近期資料和歷史資料,而無需在查詢中顯示指定資料是儲存在記憶體中還是成本優化層中。Amazon Timestream 內建了時間序列分析函式,可以實現近乎實時地識別資料的趨勢和模式。Amazon Timestream 是無伺服器服務,可自動縮放以調整容量和效能,因此無需管理底層基礎設施,可以專注於構建應用程式。
本文介紹通過Timestream、Kinesis Stream託管服務和Grafana 和Flink Connector開源軟體實現物聯網(以PM 2.5場景為示例)時序資料實時採集、儲存和分析,其中包含部署架構、環境部署、資料採集、資料儲存和分析,希望當您有類似物聯網時序資料儲存和分析需求的時候,能從中獲得啟發,助力業務發展。
架構
Amazon Timestream 能夠使用內建的分析函式(如平滑、近似和插值)快速分析物聯網應用程式生成的時間序列資料。例如,智慧家居裝置製造商可以使用 Amazon Timestream 從裝置感測器收集運動或溫度資料,進行插值以識別沒有運動的時間範圍,並提醒消費者採取措施(例如減少熱量)以節約能源。
本文物聯網(以PM 2.5場景為示例),實現PM2.5資料實時採集、時序資料儲存和實時分析, 其中架構主要分成三大部分:
實時時序資料採集:通過Python資料採集程式結合Kinesis Stream和Kinesis Data Analytics for Apache Flink connector 模擬實現從PM 2.5監控裝置, 將資料實時採集資料到Timestream。
時序資料儲存:通過Amazon Timestream時序資料庫實現時序資料儲存,設定記憶體和磁性儲存(成本優化層)儲存時長,可以實現近期資料保留在記憶體中,並根據使用者定義的策略將歷史資料移至成本優化的儲存層。
實時時序資料分析:通過Grafana (安裝Timesteam For Grafana外掛)實時訪問Timestream資料,通過Grafana豐富的分析圖表形式,結合Amazon Timestream 內建的時間序列分析函式,可以實現近乎實時地識別物聯網資料的趨勢和模式。
具體的架構圖如下:
部署環境
1.1 建立Cloudformation
請使用自己帳號 (region請選擇 us-east-1)
下載Cloudformation Yaml檔案:
https://bigdata-bingbing.s3-a...
其它都選擇預設, 點選Create Stack button.
Cloud Formation 建立成功
1.2 連線到新建的Ec2堡壘機:
修改證照檔案許可權
chmod 0600 [path to downloaded .pem file]
ssh -i [path to downloaded .pem file] ec2-user@[bastionEndpoint]
執行aws configure:
aws configure
default region name, 輸入:“us-east-1”,其它選擇預設設定。
1.3 連線到EC2堡壘機 安裝相應軟體
設定時區TZ='Asia/Shanghai'; export TZ
Install python3sudo yum install -y python3
Install python3 pipsudo yum install -y python3-pip
pip3 install boto3sudo pip3 install boto3
pip3 install numpysudo pip3 install numpy
install gitsudo yum install -y git

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
安裝grafana server:sudo yum install -y grafana
啟動grafana server:
sudo service grafana-server start
sudo service grafana-server status
配置grafana server在作業系統啟動時 自動啟動:
sudo /sbin/chkconfig --add grafana-server
1.6 安裝timestream Plugin
sudo grafana-cli plugins install grafana-timestream-datasource
重啟grafanasudo service grafana-server restart
1.7 配置Grafana 要訪問Timesteam服務所用的IAM Role
獲取IAM Role Name
選擇IAM服務, 選擇要修改的role, role name:
timestream-iot-grafanaEC2rolelabview-us-east-1
修改role trust relationship:
將Policy document 全部選中, 替換成以下內容:
{
"Version": "2012-10-17",
"Statement": [
{
"Sid":"",
"Effect": "Allow",
"Principal": {
"Service": "ec2.amazonaws.com"
},
"Action": "sts:AssumeRole"
},
{
"Sid":"",
"Effect": "Allow",
"Principal": {
"AWS": "[請替換成CloudFormation output中的role arn]"
},
"Action": "sts:AssumeRole"
}
]
}
修改後的trust relationship:
1.8 登入到Grafana server
第一次登入到Grafana Server:
- 開啟瀏覽器,訪問 http://[Grafana server public ip]:3000
- 預設的Grafana Server 監聽埠是:3000
如何獲取Ec2 Public IP地址, 如下圖所示, 訪問Cloudformation output: - 在登陸介面, 輸入 username: admin; password:admin.(輸入使用者名稱和密碼都是admin)
