Hello @Simran(OpenObserve), Could you please let me know whether the

env

field is no longer available inside RUM in the open-source version of OpenObserve? Is this an expected limitation of OpenObserve, or is there any additional configuration required from our side?

The env field is supported in the open-source version , it's a standard SDK config option

I am not saying env is not configured. Saying the Env filter dropdown in the RUM Performance UI shows "No Data Found" even after multiple sessions.

We are already using the exact configuration shown in your screenshot. The

env

field is correctly set in

openobserveRum.init()

.

The issue is specifically in the RUM Performance UI at:

<http://13.207.22.45:5080/web/rum/performance/overview>

When we click the Env dropdown filter, it shows "No Data Found" — even though sessions are being recorded successfully with

env: 'test'

configured.

We can see data in:

Service filter → shows all our services

Version filter → shows

1.0.0

Sessions tab → sessions visible

Performance metrics → LCP, INP, CLS visible

Only the Env filter dropdown shows "No Data Found"

We Are Already Using — Same Config

Our current

rum.ts

is identical to what they showed:

```// WHAT WE USE — matches O2 docs exactly

openobserveRum.init({

clientToken: 'rumztBrfmzy6HiD3jMu',

applicationId: 'react-parent-test',

site: 'openobserve.larkfinserv.com',

service: 'react-parent-test',

env: 'test', // ← env IS set correctly

version: '1.0.0',

organizationIdentifier: 'default',

insecureHTTP: false,

apiVersion: 'v1',

trackResources: true,

trackLongTasks: true,

trackUserInteractions: true,

defaultPrivacyLevel: 'allow',

sessionSampleRate: 100,

sessionReplaySampleRate: 100,

});```

which o2 version are u using >

openobserve version v0.90.2
