Hi all,
Mongo version 4.4.25
mongo node package version 4.4.1
Trace Sample showing api request with instrument like http,mongo & redis with commonjs, BUT NOT WITH ECMAScript module support.
I read this doc- ECMAScript module support | APM Node.js Agent Reference [4.x] | Elastic
But no luck. I added below line in package.json also
"start": "node app.js --experimental-loader=elastic-apm-node/loader.mjs server.mjs",
----------app.js -----------
// Import ES modules
import express from 'express';
import './apm.js'; // Assuming apm.js exports itself automatically
import cors from 'cors';
import bodyParser from 'body-parser';
import { MongoClient } from 'mongodb';
const app = express();
import { Redis } from "ioredis"
const redis = new Redis('redis://localhost:6379'); // Connect to Redis
// Redis Event Listeners
redis.on('connect', () => {
console.log('Connected to Redis');
});
redis.on('error', (err) => {
console.error('Redis connection error:', err);
});
const mongoUri = 'mongodb://localhost:27017';
const client = new MongoClient(mongoUri);
app.use(cors());
app.use(bodyParser.urlencoded({ extended: true }));
client.on('serverClosed', () => {
console.log('MongoDB server closed');
});
client.on('error', (err) => {
console.error('MongoDB error', err);
});
client.on('timeout', () => {
console.error('MongoDB connection timed out');
});
app.get('/users', async (req, res) => {
try {
await client.connect();
const cachedUsers = await redis.get('users');
if (cachedUsers) {
console.log('Returning users from Redis cache');
return res.json(JSON.parse(cachedUsers));
}
const db = client.db('mydb');
const users = await db.collection('users').find({}).toArray();
console.log('MongoDB query success');
res.json(users);
} catch (err) {
console.error('MongoDB query failed', err);
res.status(500).send('Error retrieving users');
}
});
app.listen(3100, () => {
console.log('Server is running on port 3100');
});
-----------apm.js------------
import apm from 'elastic-apm-node'
apm.start({
serviceName: 'Test app',
secretToken: '',
serverUrl: 'http://elastic:password@127.0.0.1:8200',
environment: 'local',
logLevel: 'debug',
active: true,
instrument: true,
captureBody: 'all',
captureSpanStackTraces: true,
exitSpanMinDuration: '0ms',
spanFramesMinDuration: '-1ms', // Capture all spans
transactionMaxSpans: 1000 // Increase span limit if needed
})
export const APM = apm
My elasticsearch, kibana is working fine.
Below attached image is of commonjs.
I am expecting same output for ECMA script.
i checked the logs.. for commonjs i can see mongodb logs, but the same is not present for ECAM script.
Let me know, if i am missing anything.
Thanks in advance.
