aws-xray-dotnet-webapp

An ASP.NET Web API application that has been instrumented for AWS X-Ray.

This application is written to be deployed with Elastic Beanstalk. It uses .ebextensions to setup AWS resources and configuration, which includes:

1. Create a DynamoDB table
2. Set an application confige DDB_TABLE_NAME with the create DynamoDB table name
3. Install AWS X-Ray daemon as a Windows service

How to Run The App

1. Create a RDS SQL Server DB instance. Steps

2. Construct the connection string for SQL Server and fill it into web.config key “RDS_CONNECTION_STRING”.

3. “Data Source=(RDS endpoint),(port number);User ID=(your user name);Password=(your password);”

4. Deploy the application to Elastic Beanstalk. Steps.

5. Make sure you attached an IAM role to your EC2 instance with the following policy

   
   sion": "2012-10-17",
   tement": [
   {
       "Action": [
           "sns:Publish",
           "xray:PutTelemetryRecords",
           "xray:PutTraceSegments",
           "dynamodb:PutItem",
           "dynamodb:GetItem",
           "dynamodb:DescribeTable"
       ],
       "Resource": [
           "*"
       ],
       "Effect": "Allow"
   }
   
   
   

6. Access the application using EB environment URL.

FAQ

1. What to do if I get an “Error: Internal Server Error”?
2. You can use AWS X-Ray to debug this. Go to AWS X-Ray console and find the failed trace, and look for Exception. Probably because you EC2 instance don't have the enough permission to access DynamoDB or RDS DB instance.
