# threadTimeSeriesMetric

> Fetch a time-series metric for threads with rich filter and group-by support.
Choose a `TimeSeriesMetricName` (e.g. `threads_created_count`, `threads_first_response_time__p50`), specify a
mandatory date range and bucketing interval, and optionally group results by assignee, company,
tier, label type, and more. This is the preferred reporting query when you need server-side
filtering across thread attributes. Requires `metrics:read`; grouping by assignee or filtering
`assignedToUser` to anyone other than the caller additionally requires `metricsAgent:read`.
