​
Overview

You can send in log_metadata with your observability calls, this is different from public and private metadata used for semantic filtering.

​
Use cases

log_metadata can be used on the analytics and view queries dashboards to select what results groups you want to see the accuracy for. 
{
    "customer_id": 123,
    "product": "slack-chat"
}
For example, you could send in information about what customer ran the query, where they ran it, or what dataset they ran it on and then build reports based on that later.
