Guidelines for setting storage intervals
A change in the intrahour interval does not take effect until the end of
the current intrahour interval, and existing historical data is
automatically migrated when you are changing to a longer intrahour
interval.
If the new intrahour report interval is 15 minutes, the existing 30- or
60-minute data is divided by two or four, respectively, with any
remainder falling in the last 15-minute interval. If the new intrahour
report interval is 60 minutes, two 30-minute intervals or four 15-minute
intervals are combined.
The Data Summarizing time field shows the time when the daily/
weekly/monthly summaries are done. The time is displayed in the
hh:mm a.m./p.m. format.
The Switch time zone offset field helps ensure that all
CentreVu
CMS
date and time stamps use the same clock. For example, suppose that
CentreVu
CMS runs on a machine in New York City and one of its
ACDs is in London.
CentreVu
CMS must collect all data in U.S.
Eastern time. Since New York is five hours behind London, you would
need to type –5 in this field for the London switch.
When you change the start or stop day for the week, data is archived
from the old start day through the new stop day for the week in which
the change was made.
If the start or stop time is extended, there are no records in the historical
database for the added hours before the time of the change.
If the start and stop day are the same day of the week, only one day's
worth of data is stored per week.
Wait to begin a second modification
If you are in the process of modifying data, do not open another Storage
Intervals window to start another modification. Wait until the first
modification finishes. You could lose data tables by doing simultaneous
modifications.
Turn data collection back on
When the status line reads “Successful,” turn data collection back on
and restore
CentreVu
CMS to multi-user state. Turning data collection
or
CentreVu
CMS back on before changing storage intervals is
finished may affect the accuracy of your data.
