Visualization data service settings
Use this page to configure the logging of historical data
that is available in WebSphere Virtual Enterprise reporting that can
be used for purposes such as reporting on historical data, charge
back, or capacity planning.
To view this administrative console page, click System Administration
> Visualization Data Service.
If you are a user with either a monitor or an operator role, you
can only view the visualization data service information. If you have
a configurator role, you can change the configuration. If you have
an administrator role, you have all the privileges for the visualization
data service.
- Enable log
Select to start logging historic data.
- Timestamp format
Specifies a date and time pattern that is used when logging
visualization data.
Use the SimpleDateFormat Java class to format your timestamp. For
example, to output the 12.06.2006 5:26:30:978 PM PDT timestamp,
use the following timestamp format value:
MM.dd.yyyy hh:mm:ss:SSS aaa z
For more information about the SimpleDateFormat Java class, see
the API documentation.
If you are using IBM Tivoli Usage and Accounting Manager, use a
format that separates the date and time into different fields.
- Maximum file size
Type a whole integer for the maximum log file size.
- Maximum number of historical files
Specifies a whole integer for the maximum number of logs
to generate.
- File name
Specifies the path where the log files are generated.
- Data log write interval
Specifies the time between data writes to the log files
in seconds, minutes, hours or days. The data log write interval can
be a whole number between 1 and 2147483647.
- Data transformer action
Specifies how to handle extra data points that are received
within the data log write interval.
For example, if your write interval is one minute, and data is
received every 15 seconds, four data points are received in the interval.
To throw away the first three data points, and only write the data
point at the one minute interval to the log, select Skip. To
average the four data points at the end of the interval, and write
the average to the log, select Average.
