•
the input recording sessionss session lengths and the requested
playback start and end times
To handle these differences, accumulated counts are prorated.
Percentages and rates are weight-averaged, weighted by the
number of seconds that each input sample contributes.
See Appendix C, “Specifications for Defining Playback Views”
for more information.
allow_estimation
specifies whether or not you want playback to estimate values for data
items that cannot be calculated exactly. Valid values are:
•
disallow
(the default) – causes the
hs_create_playback_view
command to return an error if it encounters data items that require
estimation.
•
allow
– causes playback to estimate values, if necessary, for certain
data items. Some data items cannot be included in a playback view
unless you allow estimation in the playback session.
This parameter is ignored if summarization_interval is
raw
.
See Table C-2 on page 165 to determine which data items require
estimation.
missing_data_option
when target is
client
, this parameter specifies how the
hs_playback_sample
command treats periods of time when no data is
available in the input sessions. Valid values are:
•
skip
(default) – when a time period contains no data, the
hs_playback_sample
command goes directly to the next time
period containing data, rather than returning a sample having no
data.
•
show
– the
hs_playback_sample
command returns a sample even
for a time period where no data is available. During client
playback, the column headers are returned with zero rows.
When target is
file
, gaps are not allowed.
