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.
About this task
Attention: You must configure the visualization
data service before you enable logging. If you need to make changes
to the configuration after you have enabled logging, you must restart
the deployment manager after you make the configuration changes.
Procedure
- In the administrative console, click System administration
> Visualization data service.
- 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.
- Select Enable log to start logging historic data.
- If logging was enabled before you configured the visualization
data service, restart your deployment manager.
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.
