Advantages of using AWS LambdaĪWS Lambda offers multiple benefits when you are working on it. Step 5 − Remember that AWS charges only when the AWS lambda code executes, and not otherwise. data is added/updated/deleted in dynamo dB tables.Step 4 − Executes AWS Lambda Code only when triggered by AWS services under the scenarios such as − For example, event from Amazon S3, Amazon API Gateway, Dynamo dB, Amazon SNS, Amazon Kinesis, CloudFront, Amazon SES, CloudTrail, mobile app etc. Step 3 − AWS Lambda which has the upload code and the event details on which the trigger has occurred. Step 2 − These are few AWS services on which AWS lambda can be triggered. Step 1 − Upload AWS lambda code in any of languages AWS lambda supports, that is NodeJS, Java, Python, C# and Go. The block diagram that explains the working of AWS Lambda in five easy steps is shown below − You pay only for the compute time you consume - there is no charge when your code is not running. AWS Lambda executes your code only when needed and scales automatically, from a few requests per day to thousands per second. What is AWS Lambda?ĭefinition of AWS Lambda as given by its official documentation is as follows −ĪWS Lambda is a compute service that lets you run code without provisioning or managing servers. Note thatAWS Lambda will work only with AWS services. All other tasks and resources such as infrastructure, operating system, maintenance of server, code monitoring, logs and security is taken care by AWS.ĪWS Lambda supports languages such as Java, NodeJS, Python, C#, Go, Ruby, and Powershell. To get working with AWS Lambda, we just have to push the code in AWS Lambda service. The code is executed based on the response of events in AWS services such as adding/removing files in S3 bucket, updating Amazon dynamo dB tables, HTTP request from Amazon API gateway etc. Monitoring and TroubleShooting using CloudwatchĪWS Lambda is a service which performs serverless computing, which involves computing without any server.Lambda Function with Custom User Applications.AWS Executing & Invoking Lambda Function.Creating & Deploying using Serverless Framework.Go back to the CloudFormation stack and select Delete.Select the Resources tab and navigate to the DeliveryBucket S3 bucket.In AWS Console, go to your CloudFormation stack.See Unsubscribe from log groups for details. You can use the log groups auto-discovery method described in Subscribe by reading log groups from file and pass the auto-discovery output file to the unsubscribe command. Select one of the listed log streams and look for exceptions in the logs.On the Lambda screen, select the Monitor tab and then select Logs.Select the Resources tab and then select the link next to Lambda.Inspect the dashboard for any obvious issues.It will have a name like DynatraceLogForwarder-SelfMonitoring-eu-north-1-dynatrace-aws-logs, where the middle part is the AWS region and the last part is the stack name you chose (the default is dynatrace-aws-logs). Find the self-monitoring dashboard for AWS log forwarding.In AWS Console, go to CloudWatch Dashboards.To verify AWS log forwarder connectivity and inspect operational logs In Events, look for any events with a failed status.In Parameters, check if the parameter values are consistent with the values you provided during deployment.In Stack info, check the stack status it should be CREATE_COMPLETE.If you find any issues or discrepancies in any of the fields below, select Delete to delete the stack, and then repeat the deployment process.Select your log forwarder stack from the list on the left by stack name (the default value is dynatrace-aws-logs).Syntax: TagKey1=TagValue1 TagKey2=TagValue2 … Optional A list of tags to associate with the stack that is created or updated. For values over 8192 there's also a change in Dynatrace settings needed - you need to contact Dynatrace One for that. If log exceeds this length it will be truncated. Optional The name of the CloudFormation stack where you want to deploy the resources. Optional If true, the log forwarder Lambda function verifies the SSL certificate of your Dynatrace environment URL. If you choose to use an existing environment ActiveGate, set it to your ActiveGate endpoint: Note: To determine, see environment ID. ![]() Required The API URL to your Dynatrace SaaS environment logs ingest target. For TARGET_API_TOKEN, enter your API token.For TARGET_URL, enter the API URL of your ActiveGate endpoint: To learn how to determine your environment ID, see environment ID.Set the following environment variables, making sure to replace the placeholders ( ) with your own values, as follows. ![]()
