    Description

      As of 3.2.0, index access statistics are only recorded for user operations. We do not record index use by internal operations, which include:

      1. TTL index use to remove expired documents.
      2. Index usage for chunk split, move and post-move deletion.

      We need to either:

      1. Make clear in our documentation that statistics are only recorded for user operations.
      2. or add index access recording for these operations
