Statistics Actions
The following actions can be performed on statistics/datasets:
Table 10 Actions Performed on Statistics/Datasets
|
|
Open
|
Begin reading from the statistic (every second) and cache values
in memory as a dataset. In Open Worksheets, statistics are opened
when they are added to the view, allowing them to be graphed in
real-time. The data is kept in memory while the statistic is being
viewed.
|
Close
|
Closes the statistic view, discarding the in memory cached
dataset.
|
Archive
|
Sets the statistic to be permanently opened and archived to disk.
If the statistic had already been opened, then all cached data in
memory is also archived to disk. Archiving statistics creates
permanent datasets, visible in the Datasets view (those with a
non-zero "on disk" value). This is how statistics may be recorded
24x7, so that activity from days, weeks and months in the past can
be viewed after the fact.
|
Discard data
|
Manage the amount of data stored for a particular statistic. You
can select to discard the entire dataset or select to remove one of
the following granularities of archived data: Second, Minute, or
Hour. Note that if you want to delete a higher level of granularity,
you must also delete any lower level of granularity. For example, to
delete the Minute granularity, you must also delete the Second
granularity. If you select to not discard the entire dataset, you
can discard older data and retain only newer data. You enter an
integer value in the "Older than" text box and then select the unit
of time: hours, days, weeks, or months. For example, if you want to
only retain three weeks of stored data for the selected statistic,
you enter a "3" into the "Older than" text box and then select
"weeks" from the drop-down menu.
|
Suspend
|
Pause an archived statistic. New data will not be read, but the
existing disk archive will be left intact.
|
Resume
|
Resumes a previously suspended statistic, so that it will continue
reading data and writing to the archive.
