<@U03A2NXQM39> have you checked this? <https://signoz.io/docs/instrumentation/nodejs/|https://signoz.io/docs/instrumentation/nodejs/>

Hi <@U01HPVB0D2S> i gone through this document

pm2 just span a different process in different core...

<@U03A2NXQM39> Is the standard way of running `pm2` not working? Something like

`pm2 start -r ./tracing.js index.js`

let me check that <@U01HPVB0D2S> we can pass the environmental variables in .env

```module.exports = {
  apps : [{
    name: 'app-name',
    script: '/app-name/bin/www',

    // Options reference: <https://pm2.io/doc/en/runtime/reference/ecosystem-file/>
    instances: 1,
    exec_mode : "cluster",
    autorestart: false,
    watch: false,
    max_memory_restart: '1G',
    args: [],
    env: {
      APP_PORT: '3023'
    }
 }

]
};```

now  how to modify the script to start the tracing.js

<@U02SS3ZAMKQ> do you have insights on this?

```'/app-name/bin/www```
<@U03A2NXQM39> is this a script you are running? Is this possible to add steps importing tracing.js in this script

If you are not able to figure out, might be easier to jump on a call sometime to understand your setup

Let me check with importing the file inside the js file and if not will connect in the call.
