awslambdamonitor 1.0.0

AWS Lambda监视器

aws lambda monitor是一个运行在aws lambda中的小型监视工具。 该工具由cloudwatch计划的任务定期触发，或者 通过电子邮件触发的事件按需发送。用这个工具你可以监视 免费提供服务器上的服务并接收警报 有问题时发邮件。

如何构建awslambdamaonitor并将其上载到aws

构建并打包virtualenv

要构建包含virtualenv的zip文件，请启动amazon linux EC2实例（因为这是AWS lambda函数运行的环境 在中）。按如下所示创建zip文件

sudo yum groupinstall 'Development Tools'
sudo yum install libyaml-devel libffi-devel openssl-devel
virtualenv build-aws-lambda-monitor-environment
build-aws-lambda-monitor-environment/bin/pip install pyOpenSSL paramiko ecdsa pycrypto python-whois PyYAML ndg-httpsclient pyasn1 requests
pushd build-aws-lambda-monitor-environment/lib/python2.7/dist-packages/
zip -r ~/awslambdamonitor.zip *
popd

pushd build-aws-lambda-monitor-environment/lib64/python2.7/dist-packages/
zip -r ~/awslambdamonitor.zip *
popd

rm -rf build-aws-lambda-monitor-environment

scp从amazon linux机器获取文件

从ec2实例下载压缩后的virtualenv并 销毁实例。

将显示器添加到压缩的virtualenv

zip --junk-paths awslambdamonitor.zip awslambdamonitor/monitor.py

将配置添加到压缩的virtualenv

zip --junk-paths awslambdamonitor.zip awslambdamonitor/monitor.yaml

将包发布到aws lambda并设置cloudwatch调度作业

AWS_ACCOUNT_ID=123456789012
AWS_PROFILE=myprofilename
AWS_REGION=us-west-2
aws lambda create-function --function-name monitor --runtime python2.7 --timeout 30 --role arn:aws:iam::$AWS_ACCOUNT_ID:role/lambda_basic_execution --handler monitor.monitor --zip-file fileb://awslambdamonitor.zip  --profile $AWS_PROFILE --region $AWS_REGION
aws lambda invoke --function-name monitor --log-type Tail --payload '{"account": "123456789012","region": "us-east-1","detail": {},"detail-type": "Scheduled Event","source": "aws.events","time": "1970-01-01T00:00:00Z","id": "cdc73f9d-aea9-11e3-9d5a-835b769c0d9c","resources": ["arn:aws:events:us-east-1:123456789012:rule/AWSLambdaMonitor5Minutes"]}'  --profile $AWS_PROFILE --region $AWS_REGION output.txt

aws lambda update-function-code --function-name monitor --zip-file fileb://awslambdamonitor.zip --profile $AWS_PROFILE --region $AWS_REGION

aws events put-rule --name AWSLambdaMonitor5Minutes --schedule-expression 'rate(5 minutes)' --state ENABLED --profile $AWS_PROFILE --region $AWS_REGION
aws events put-rule --name AWSLambdaMonitorDaily --schedule-expression 'rate(1 day)' --state ENABLED --profile $AWS_PROFILE --region $AWS_REGION

aws lambda add-permission --function-name monitor --statement-id AWSLambdaMonitor5MinutesID --action 'lambda:monitor' --principal events.amazonaws.com --source-arn arn:aws:events:$AWS_REGION:$AWS_ACCOUNT_ID:rule/AWSLambdaMonitor5Minutes --profile $AWS_PROFILE --region $AWS_REGION
aws lambda add-permission --function-name monitor --statement-id AWSLambdaMonitorDailyID --action 'lambda:monitor' --principal events.amazonaws.com --source-arn arn:aws:events:$AWS_REGION:$AWS_ACCOUNT_ID:rule/AWSLambdaMonitorDaily --profile $AWS_PROFILE --region $AWS_REGION

aws events put-targets --rule AWSLambdaMonitor5Minutes --targets '{"Id" : "AWSLambdaMonitor5Minutes-monitor", "Arn": "arn:aws:lambda:$AWS_REGION:$AWS_ACCOUNT_ID:function:monitor"}' --profile $AWS_PROFILE --region $AWS_REGION
aws events put-targets --rule AWSLambdaMonitorDaily --targets '{"Id" : "AWSLambdaMonitorDaily-monitor", "Arn": "arn:aws:lambda:$AWS_REGION:$AWS_ACCOUNT_ID:function:monitor"}' --profile $AWS_PROFILE --region $AWS_REGION

通过更新和上传来迭代代码

如果要扩展或修改监视器，可以更新正在运行的 这样的代码

# Update the file in the zip archive
zip --junk-paths awslambdamonitor.zip awslambdamonitor/monitor.py

# Upload the new zip file
aws lambda update-function-code --function-name monitor --zip-file fileb://awslambdamonitor.zip --profile $AWS_PROFILE --region $AWS_REGION

如果要更改配置

# Update the file in the zip archive
zip --junk-paths awslambdamonitor.zip awslambdamonitor/monitor.yaml

# Upload the new zip file
aws lambda update-function-code --function-name monitor --zip-file fileb://awslambdamonitor.zip --profile $AWS_PROFILE --region $AWS_REGION

测试事件

下面是一个可以在aws lambda web控制台中使用的示例事件 测试监视器
