I tried adding external-serverless for monitoring some kafka broker as they are already exposing prometheus endpoints from MSK Open-Monitoring  
`pmm-admin add external-serverless` runs and give success message but I am not able to see any metrics in the explorer tab  
Not sure how can I debug this.  
Please help me if someone is aware about this issue

I am deploying it on a container running on EKS node

Here is the general data flow for the architecture  
(MSK) → DEV EKS (POD) (External serverless services) → EKS (POD) (Pmm-server)

Please provide the full command used to add the external monitoring. Have you looked at `journalctl` for any errors from the pmm-agent?

I have not deployed pmm as systemd service as these are running on lightweight pods so didn’t want to mess with that  
and as of the full command that I am using is as follows

```auto
pmm-admin add external-serverless --debug --url="http://broker-url.com:11001/metrics"--group=kafka

```

Just replacing the broker-url with the actual broker URL  
and already checked the connectivity with the pod(pmm-kafka) to broker is there as well as pod(pmm-server) to broker is also there

What do the pmm-agent logs say, during `add external-serverless` and after adding?

on the pod I get the confirmation like  
External Service added.  
Service ID : \<service\_id\>  
Service name: test-service  
Group : external

but on the console it registers a new node that is not there and don’t have any agents running

msk-kafka-broker-1-node remote [Failed]

[1/1 not running] /agents)

Node ID: node\_id

Service Names

[msk-kafka-broker-1]

here is an example of test service that got added
