[英]How to Configure AWS X-Ray for node.js app not using Express middleware?
我正在嘗試將AWS X-Ray與托管在AWS Lambda(無服務器)上的nodejs api集成在一起。 X-Ray使用快速中間件按預期用於api的方式工作,並且能夠在AWS Console上查看跟蹤。 對於沒有快速框架的異步功能,我在集成時會遇到問題。
嘗試啟用手動模式,但面臨-Lambda 不支持手動模式錯誤。
引用了此 - 開發自動模式的自定義解決方案部分,但沒有運氣。
有人可以幫我這個忙嗎?
'use strict';
const AWSXRay = require('aws-xray-sdk-core');
const Aws = AWSXRay.captureAWS(require('aws-sdk'))
const capturePostgres = require('aws-xray-sdk-postgres');
const { Client } = capturePostgres(require('pg'));
module.exports.test = async (event, context) => {
var ns = AWSXRay.getNamespace();
const segment = newAWSXRay.Segment('Notifications_push');
ns.enter(ns.createContext());
AWSXRay.setSegment(segment_push);
.... };
因此,在Lambda中時,SDK會自動創建一個占位符(外觀)段。 此處有更深入的說明: https : //github.com/aws/aws-xray-sdk-node/issues/148
所有你需要的是:
const AWSXRay = require('aws-xray-sdk-core');
//lets patch the AWS SDK
const Aws = AWSXRay.captureAWS(require('aws-sdk'));
module.exports.test = async (event, context) => {
//All capturing will work out of box
var sqs = new AWS.SQS({apiVersion: '2012-11-05'});
var params = {...}
//no need to add code, just regular SQS call
sqs.sendMessage(params, function(err, data) {
if (err) {
console.log("Error", err);
} else {
console.log("Success", data.MessageId);
}
});
//if you want to create subsegments manually simply do
const seg = AWSXRay.getSegment();
const subseg = seg.addSubsegment('mynewsubsegment');
subseg.close();
//no need to close the Lambda segment
};
