172         supported: none and scan-time. The default is none. By setting
173         ``advisor_mode`` to scan-time, the scan time advisor is enabled.

310 decides how aggressive the scan time advisor scans candidate pages. Lower
311 values make the scan time advisor to scan more aggressively. This is the most
312 important parameter for the configuration of the scan time advisor.
318 The ``pages_to_scan`` parameter is re-calculated after a scan has been completed.
