# too_many_series

An audit count would return too many series times buckets (400).

## Meaning

A count grouped by a column with many values, over many buckets, would carry more
than 32,768 counts in one answer.

## Impact

The chart is not drawn. It is a caller error, typically a grouping by a high
cardinality field such as an address over a long, fine-grained window.

## Diagnosis

Read `detail`, and compare the grouping and the number of buckets with the cap.

## Mitigation

- As an admin-API caller: narrow the filters or the window, or choose a coarser
  bucket. For a long tail, use the ranking endpoint instead.

## Escalation

Escalate only when a small grouping over a short window is refused. Open an issue
with the request id, the query parameters and the server version.
