Newrelic demo

[huntharo]

Issue Demonstrated

• newrelic@10.4.0 logs DynamoDB access on the Database tab in APM with actual operations like DynamoDB GetItemCommand, DynamoDB PutItemCommand, and DynamoDB UpdateItemCommand
• newrelic@11.1.0 removes the DynamoDB access from the Database tab and instead logs access to the dynamodb HTTPS endpoint as an External Service without insight into which commands were run and how much time they took
• It appears that this was broken in: feat: updated aws sdk v3 instrumentation to function with require-in-… newrelic/node-newrelic-aws-sdk#205
  • This PR completely removed the lib/v3/lib-dynamodb.js and lib/v3/client-dynamodb.js files from @newrelic/aws-sdk@7.0.0
  • This PR also changed the nr-hooks.js file, changing the type of the hooks for smithy-client and completely removing the hooks for lib-dynamodb and client-dynamod

Running the Demo

• npm i to install modules
• npm run build to compile the TypeScript
• Allow the example to reference the local module by name
  • npm link
  • npm link @pwrdrvr/dynamodb-session-store
• Bundle the example (running it with ts-node results in no data being sent to NR)
  • npm run build:example:express
• Run the example with your NR license key
  • NEW_RELIC_LICENSE_KEY=my_license_key npm run example:express:newrelic
• Hit the login route a few times
  • http://localhost:3001/login
• View dynamodb-session-store in NewRelic APM

Comparing newrelic 10.4.0 to newrelic 11.1.0

• 10.4.0 logs DynamoDB under the Database tab
• 11.1.0 logs DynamoDB calls as External Services not as Database

Run this command (with license key substituted) to test changed versions:

rm -rf node_modules package-lock.json && npm i && npm link && npm link @pwrdrvr/dynamodb-session-store && npm run build:example:express && NEW_RELIC_LICENSE_KEY=my_license_key npm run example:express:newrelic
