The Data Virtualization service provides a
dashboard for monitoring, managing, and exploring the service instance. This monitoring and
exploring dashboard is powered by IBM®
Db2® Data Management Console.
Before you beginBefore you use the Monitor dashboard and
Explore capabilities in Data Virtualization, ensure that the IBM
Db2 Data Management Console service is installed. For details, see Installing Db2 Data Management Console.
About this task
Db2 Data Management Console is a browser-based console that
helps you administer, explore, monitor, and manage the performance of your Data Virtualization service instance by using one or more of the
key performance indicators, known as metrics. For details, see Working with Db2 Data Management Console.
Click Data Virtualization service health, based on the following
metrics: to get an overview of the
||Indicates whether the service is up or down, and the relevant alerts.
||Indicates whether the system is responding well to the incoming requests.
||Indicates how much workload the system is handling.
||Indicates the resource usage of the service in terms of CPU, memory, storage, and log
||Indicates the percentage of time that is taken for service calls.
- Click Data Virtualization, based on the
following metrics: to get performance data about
queries executed in
||See a list of the SQL statements that are currently running or that ran recently on
You can use these metrics to
identify costly or long running statements. You can cancel individual statements or disconnect a
user or application if the statement needs to be stopped.
||Displays the details of executed SQL statements as system activity.
||See information about statements that previously ran on Data Virtualization. For example, you can see the number of
executions and the total amount of CPU used for these executions.
You can use these metrics to
identify statements that use a disproportionate amount of system resources.
||Displays the aggregated execution metrics for procedures, external procedures, compiled
functions, external functions, compiled triggers, and anonymous blocks invoked since the service was
activated in Db2 Data Management Console.
- Click to get an overview of the
service usage, based on the following metrics:
||Displays the top consumers of the system resources.
||See the different users or applications that have open connections to the service. A user
or application can open multiple connections.
You can use these metrics to find the source of
- Click to get an overview of query
performance, based on the following metrics:
||Displays a summary of all connections established to the console.
||Displays the information for each data partition used by Data Virtualization.
|WLM workload summary
||Represents the accumulation of all metrics for requests that were submitted by connections,
and were mapped to the identified workload objects. This metric is based on Workload
|WLM service class summary
||Represents the accumulation of all metrics for requests that have executed under the
indicated service subclass.
- Click to get an overview of input/output for
each data partition, based on the following metric:
||Data Virtualization uses the Db2 buffer pools to store cached data and to improve
service performance. Adequate buffer pool size is essential for good service performance because it
reduces the disk I/O, which uses a considerable amount of time.

occur on Data Virtualization. For details, see Event monitor
Required role: To access these profiles, you must have the Data Virtualization Admin role.
- Click Explorer to access the following information in Data Virtualization:
- Remote tables
- Authorization, such as groups, roles, and users that have permissions to the objects in the
- Application objects, which include stored procedures and user-defined functions.
Additionally, Data Virtualization Admins can explore
schemas, user-defined types, MQT statements, and sequences.
