ThreadAggregateStatsParams

filter is a deprecated, unscoped LangSmith filter expression evaluated against trace root runs. Kept for compatibility with deployments that serve this endpoint via the legacy ClickHouse backend (no SmithDB query service configured); prefer trace_filter, tree_filter, or thread_filter otherwise, since those require SmithDB.

max_start_time is the exclusive upper bound on thread activity (RFC3339 date-time). Defaults to now (UTC) when omitted.

min_start_time is the inclusive lower bound on thread activity (RFC3339 date-time). Defaults to 1 day before now (UTC) when omitted.

project_id is the tracing project UUID.

select lists the aggregate statistics to compute and return. At least one value is required.

thread_filter narrows eligible threads using a LangSmith filter expression evaluated against the complete thread summary.

trace_filter narrows eligible threads to those containing a trace whose root run matches this LangSmith filter expression.

tree_filter narrows eligible threads to those containing a matching run anywhere in a trace tree.
