(DI-2305) Collector for Database monitoring

The technical name of the Collector for Database monitoring is /DVD/MON_CL_COL_DB.

This collector collects information about the database, including also sizes for tables or indexes available on the database or configured tablespaces.

Monitoring of tablespaces for the database is available only for the system(s) with the Oracle or DB2/DB6 database.

Input table

This collector uses two input tables:

1. /DVD/MON_DBTS_I1 - Inputs for DB tablespaces monitoring setup

The rules define which tablespaces are included in the KPI value calculation. This input table provides the following fields:

Technical name

Column name 

Description

Technical name

Column name 

Description

KPI

KPI name

Name of the KPI that rule applies to

TABLE_SPACE_NAME

Tablespace name

Name of the tablespace that rule applies to

VALUE_RESULT

Value result

Defines the function for requested KPI result value

CHANGED_BY

Last changed by user [automatically filled]

User who last changed the specific record

CHANGED_AT

Last changed time [automatically filled]

Time when the specific record was changed

CREATED_BY

Created by user [automatically filled]

User who created the specific record

CREATED_AT

Created at the time [automatically filled]

Time when the specific record was created

2. /DVD/MON_DBTS_I2 - Inputs for index monitoring setup on DB tablespaces

This input table is relevant only the for the external Oracle database monitoring, so it does not make sense to configure it for other databases.

The rules define which indexes from the external database should be included in the monitoring. This input table provides the following fields:

Technical name

Column name 

Description

Technical name

CHANGED_AT

Last changed time [automatically filled]

Time when the specific record was changed

CREATED_BY

Created by user [automatically filled]

User who created the specific record

CREATED_AT

Created at the time [automatically filled]

Time when the specific record was created

Detail table

The collector provides three detail tables that store additional information for monitored tablespace or indexes.

1. DB tablespace size statistics (all)

The technical name of the detail table for DB tablespace size statistics (all) is /DVD/MON_S_DB_TABLE_SPACE. It reports the size statistics for all tablespaces configured on the database in the following fields:

Technical name

Description

Technical name

Description

TIMESTAMP

Time when the records are saved into the detail table [automatically added]

SID

System ID [automatically added]

TS_NAME

Tablespace name

TS_SIZE

Total size in MB

TS_FREE

Free size in MB

TS_USED_P

Percentage of used size

AUTO_EXTEND

Is tablespace auto-extended?

2. DB tablespace size statistics (per KPI)

The technical name of the detail table for DB tablespace size statistics (per KPI) is /DVD/MON_S_DB_TS_DETAIL. It reports the size statistics only for tablespaces defined in the input table /DVD/MON_DBTS_I1 for specific KPI. Detail table contains the following fields:

Technical name

Description

Technical name

Description

TIMESTAMP

3. Database indexes

The technical name of the detail table for Database indexes is /DVD/MON_S_DB_INDEXES. It reports the index size only for indexes defined in the input table /DVD/MON_DBTS_I2 for specific owners and tablespace. This detail table contains the following fields:

Technical name

Description
