使用 Nodejs ( lambda ) 获取 AWS QLDB 的 X 射线交互

Question

I tried this way, But I want more detailed requests inside QLDB x-ray interactions.

const AWSXRay = require("aws-xray-sdk");
/** QLDB x-ray */
AWSXRay.captureAWS(require("aws-sdk")); //For this x-ray show sendCommand() Requests, But info not in detail

AWSXRay.captureHTTPsGlobal(require("https")); //For this x-ray show 'POST https://session.qldb.xx-xxx-x.amazonaws.com/', But info not in detail
/** QLDB x-ray */

Let me know if anyone tried in a different way apart from the above option I mentioned.

in case if you know just share your snippet code here. ( X-Ray interactions with QLDB )

Answer 1

Currently, QLDB is not integrated with AWS X-Ray. This leaves the following options to trace interactions with QLDB:

• Tracing AWS SDK calls: https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-nodejs-awssdkclients.html . An example here is: AWSXRay.captureAWS(require('aws-sdk')) .
• Tracing calls to downstream HTTP web services: https://docs.aws.amazon.com/xray/latest/devguide/xray-sdk-nodejs-httpclients.html . An example here is AWSXRay.captureHTTPsGlobal(require('http')) .

These options - as you point out - do not provide much outside of identifying the operation/API invoked or the URL a request is made to. What further details are you interested in viewing in the traces? For instance, are you interested in identifying the exact commands - such as CommitTransaction or ExecuteStatement - sent through in a SendCommand API call? For the commands supported by the SendCommand API, see: https://docs.aws.amazon.com/qldb/latest/developerguide/API_QLDB-Session_SendCommand.html .
