Hi all
I've install a ECK cluster in a 5 workers nodes K8s.
The problem Im having is that I'm not getting any document with information about the field/value metricset.name : "process".
apiVersion: beat.k8s.elastic.co/v1beta1
kind: Beat
metadata:
name: metricbeat
spec:

The thing im not having any data for the metricset.name : "process"
for any of the workers nodes of the clusters. For other onpremise servers it works well and show data, but not for my workers where I have my metricbeat running as deamonset.
Any idea why this is like this?
Thank you very much and regards.

perhaps try
- '.*'
Single quotes or the documented
processes: ['.*']

Hi Stephen. Thank you for the fast answer.
I've tried both ways without success.
Anyway I've got an other environment with k3s where I will try the same config to get more conclutions.
Just so everybody has more info I get here the whole metricbeat config. Maybe I didnt provide something I didnt consider important:

Could it be something to do with my kubernetes config?

Hi all again!
I've just used the same deployment in my house lab environment with k3s as kubernetes cluster with a master and a worker node.
It worked perfectly well. So I guess this is something to do with my cluster's settings. I will ask to my colleagues who installed to check if they have a clue.
Thank you very much all anyway
Thanks a lot Stephen

out of pure curiosity, did you enable capturing cluster metrics using elastic k8s integration with ksm?

Hi Sunile.
No, I havent enabled that.
Regards.
My .02 (opinion) if you are trying to fetch host and/or pod level metrics, leverage KSM + Elastic KSM integration.

Not the case, thank you Sunile.
