Hi,

Is there a way to filter hostnames based on environment ( sandbox / dev ) ?

I tried with adding labels to /etc/otelcol-contrib/config.yaml but it didn't help

`processors:`
  `attributes:`
    `actions:`
      `- key: "environment"`
        `value: "development"`

You should be able to edit variable to filter on environment with a WHERE clause.

```SELECT DISTINCT(JSONExtractString(labels, 'host_name'))
FROM signoz_metrics.time_series_v2
WHERE not has(JSONExtractKeys(labels), 'k8s_node_name') and has(JSONExtractKeys(labels), {{.environment}})```

If this doesn't show any hosts then it means there are no metric emitting host meta data
