Database Usability Collection

The following table provides a list of the Database Usability metrics that are collected, and a description for each.


Metric	Description
DB_RESPONSE_TIME	The response time of a query representing the general workload (“select 1 from sysibm.sysdummy1”) when the connection is already open.
DB_CONNECTION_TIME	The time for establishing the connection.
DB_CONNECTION_AVAILABILITY	The percent of nodes for which the connection is available.

Database Parameters Collection

The following table describes the metrics that are collected for each database configuration parameter.


Metric	Description
DATABASE_NAME	The name of the monitored database.
NAME	The configuration parameter name.
CURRENT_VALUE	The current value of the configuration parameter stored in memory, in partition/member 0.
VALUE_FLAGS	Provides information about the current value of the configuration parameter. Values: NONE — No additional information AUTOMATIC — The configuration parameter has been set to automatic
DEFERRED_VALUE	The value of the configuration parameter on disk. For some database configuration parameters, changes only take effect when the database is reactivated. In such cases, all applications must first disconnect from the database. (If the database was enabled, then it must be deactivated and then reactivated.) The changes take effect with the next connection to the database.
DATATYPE	The configuration parameter data type.
MODIFIED	Indicates whether the value changed since the last collection. If the value changed on disk, but the instance is still using the previous value, the value of this parameter is 0.

Database Instance Parameters Collection

The following table describes the metrics that are collected for each database instance configuration parameter.


Metric	Description
INSTANCE_NAME	The database instance name.
NAME	The configuration parameter name.
CURRENT_VALUE	The current value of the configuration parameter stored in memory, in partition/member 0.
VALUE_FLAGS	Provides specific information about the current value of the configuration parameter. Values: NONE — No additional information AUTOMATIC — The configuration parameter has been set to automatic
DEFERRED_VALUE	The value of the configuration parameter on disk. For some database configuration parameters, changes only take effect when the database is reactivated. In such cases, all applications must first disconnect from the database. (If the database was enabled, then it must be deactivated and then reactivated.) The changes take effect with the next connection to the database.
DATATYPE	The configuration parameter data type.
MODIFIED	Indicates whether the value changed since last collection. If the value changed on disk, but the instance is still using the previous value, the value of this parameter is 0.

Database Instance Registry Variables Collection

The following table describes the metrics that are collected for each database instance registry variable.


Metric	Description
INSTANCE_NAME	The name of the monitored instance.
REG_VAR_NAME	The name of the DB2 registry variable.
REG_VAR_VALUE	The current value of the DB2 registry variable in memory.
REG_VAR_ON_DISK_VALUE	The current setting of the DB2 registry variable on disk. For DB2 versions prior to version 10, the current setting is not available, so the value of this parameter is “N/A”.
LEVEL	Indicates the level at which the DB2 registry variable acquires its value. The possible return values and the corresponding levels that they represent are: I — Instance G — Global N — Database partition E — Environment
MODIFIED	Indicates whether the value changed since last collection. If the value changed on disk, but the instance is still using the previous value, the value of this parameter is 0.
