Hi,

I'm trying to test RUM agent on a docker based Elastic APM (6.4.1) on an ubuntu server.  
Whereas everithing works using elastic-apm-node, I'm unable to make elastic-apm-js-base works.

I have this error while running APM: Platform is not supported!

Here is my really simple apm-server.yml file :

```
apm-server:
  host: 0.0.0.0:8200
  rum:
    enabled: true

output:
  elasticsearch:
    hosts: elasticsearch:9200

```

What am I missing to make it work ?

Hi,

Thanks for your interest in Elastic APM.  
As the error message suggests you're using the RUM JavaScript agent in a platform that is not supported.  
The RUM agent is designed to monitor frontend JavaScript application performance that run in the browser, you can see the table of supported browsers [here](https://github.com/elastic/apm-agent-js-base).

You can find instructions on how to add the agent to your frontend application [here](https://www.elastic.co/guide/en/apm/agent/js-base/current/getting-started.html).

Would you please provide more detail about your application and your use-case?  
Are you trying to monitor a server-side rendered frontend application? Or do you want to add the RUM agent automatically to all of the pages served from your server application?

Cheers,  
Hamid

Hmm, I totally missed the fact that this agent is for frontend...  
My bad, I don't need frontend monitoring for now.  
Thank you for your answer.
