      Context

      When running db.command('collstats', collection_name), I'm getting an OperationFailure exception for all collections.

      Please note:

      1. I'm connecting to a DocumentDB cluster.
      2. The same script works with no exception when connecting to a Mongo Atlas cluster.

      Script:

       

      def mongo_stats(config_file: str):
    config = read_config(config_file)
    cluster_name = config['cluster_name']
    mongo_client = MongoClient(**config['cluster_connection_options'])
    for db_name in mongo_client.list_database_names():
        db = mongo_client[db_name]
        for collection_name in mongo_client[db_name].list_collection_names():
            _log.info('Getting stats for <%s> <%s>', db_name, collection_name)
            try:
                collection_stats = db.command('collstats', collection_name)
            except OperationFailure as e:
                _log.error('OperationFailure while getting stats:\n%s', e)
    _log.info('Done')

      Log extract:

      Definition of done

      db.command('collstats', collection_name) shouldn't raise any exception and should return the collection statistics.

      Pitfalls

      The issue seems to be specific to DocumentDB.
