MetricBeat - Unable to create dynamic namespace

MetricBeat - Unable to create dynamic namespace.

My project requirement is to create a dynamic namespace(based on hostname).
How do i get access to host name or beat name inside metricbeat.yml

I tried something similar to namespace: "[host][name]" but no luck. Could you guide me how to add dynamic namespace?

I'm not sure if this is going to work out, but you can try with:

namespace: "%{[]}"


namespace: "%{[]}"

I tried these already but it doesn't pick the beat name.

${path.config} is working for namespace but its useless as it produces path.

I have gone through fields.yml file there are lot of fields like,, beat.version..... but accessing it under metricbeat.yml for namespace is still not known.
Am wondering how it can be accessed under elasticsearch output but why not in namespace?

hosts: ["localhost:9200"]
index: "metricbeat-%{[beat.version]}-%{+yyyy.MM.dd}"
Am confused. :frowning:
Any idea?

You have access to all environment variables, as per

You should be able to do:

namespace: ${HOSTNAME}

Best regards

No.It doesn't help. It works under ElasticSearch index name but not under namespace.
