The visualization data service logs historic data in text files
for reuse with other charting programs. Historic data is logged in comma-separated
values with time stamps in standard long value from the java.util.Date class.
By using the visualization data service, you can log historical data, calculate
charge back values, or perform capacity planning.
Before you begin
You must use the deployment manager to implement this feature. Ensure
that if you are using multiple core groups, they are correctly
bridged
If you are a user with either a monitor or an operator administrative
role, then you can only view the visualization data service information. If
you have a configurator administrative role, then you can change the
configuration. If you have an administrator role, then you have all
the privileges for the visualization data service.
Procedure
- In the administrative console, click System administration >
Visualization data service.
- Select Enable log to start logging historic data.
- In the Maximum file size field, type a whole integer for
the maximum file size for logs.
- In the Maximum number of historical files field, type a
whole integer for the maximum number of logs to be generated per historic
cache type.
- In the File name field, type the path where the log files
are generated. You can use a variable in the file name value, for
example: ${LOG_ROOT}/visualization.
- In the Data log write interval field, type a whole number
between 1 and 365 for the interval in which the logs are
generated in seconds, minutes, hours, or days.
- From the Data transformer action list, select Average or Skip to
specify how to transform data when the interval reaches its maximum value.
More data points are provided than you might want to use. The AVERAGE option
averages the existing data points between the specified interval, and the SKIP option
skips the data points to only use the points specifically at the intervals.
Results
Operational data is exported to the file name that you specified.
What to do next
Now that you have configured the visualization data service, you
can import data into an external charting program.
