CHAPTER 4 Command Reference
User’s Guide

•
If target is
client
, the client retrieves the data using the
hs_playback_sample
command. Playback can occur from
recording sessions that are still in the process of recording.
•
If target is
file
, the client does not retrieve any data for this
playback session; instead, Historical Server creates a new session
and fills the data files for that new session with the data from this
playback session. The accessibility of the new session is
determined by the protection_level parameter. The user who
invokes this command is the owner of the new session. The
hs_initiate_playback
command creates the new session.
Playback is restricted to sessions that are finished recording as of
when you submit the
hs_create_playback_session
command.
•
If target is
file
and multiple playback sessions are used as input,
no time gaps are allowed. For example, if you collected data from
9 a.m. to 5 p.m. every day from Monday through Friday, you
could not play back those five recording sessions to create a new,
summarized, weekly session. However, if you eliminate the time
gaps by collecting data from 9 a.m. to 9 a.m. every day from
Monday through Friday, you could use the playback feature to
create a new, summarized weekly session. Another way to
eliminate the time gaps is to keep the 9 a.m. to 5 p.m. recording
session, but add another set of recording sessions scheduled from
5 p.m. to 9 a.m. Use a longer sample interval for the off hours to
reduce the volume of data collected.
•
The value of the summarization_interval parameter used in the
hs_create_playback_session
command affects the rules that the
hs_create_playback_view
command uses to define views.
hs_create_playback_view
Description
Specifies a view from the input recording sessions that you want to include
in the playback session. Also specifies the data items in each view that you
want to play back.
Syntax
hs_create_playback_view view_name,
[data_item_name_1, data_item_stat_1
[,data_item_name_2, data_item_stat_2]...]
