Database Administrator (DBA) report discovery

Discovery and Service Mapping uses the Patterns extension sections to provide a Database Administrator report (DBA report) for the Apache Cassandra, Microsoft SQL, MySQL, MongoDB, and Oracle databases. The extension sections for each DB pattern populate the related entries tables. Discovering some of these resources may require updating to the latest version of the Discovery and Service Mapping Patterns application from the ServiceNow Store.

Prerequisites

Verify the plugins setup

• CMDB CI Class Models 1.49.0 (September 2023)
• Discovery and Service Mapping Patterns 1.8.0 (September 2023)

Verify the system properties are enabled

By default, the system properties for DBA reports are set to false. To enable the report collection, verify that the system properties value for each pattern is set to true.

Pattern	System property
Cassandra	cassandra_dba_report_enabled
MongoDB	mongo_dba_report_enabled
MSSQL DB On Windows	mssql_dba_report_enabled
My SQL server On Windows and Linux	mysql_dba_report_enabled
Oracle DB	oracle_dba_report_enabled

Verify the configuration of the credentials

For more information, see Applicative credentials.

MongoDB execute command	Applicative credentials should have read access to run “getSiblingDB (databaseName)”
Apache Cassandra execute command	Discovery credentials should have read access to “nodetool”
MySQL tables and execute commands	Discovery credentials should have read access to: “information_schema.tables” table​ run “show databases” command
Microsoft SQL tables	Discovery credentials should have read access to the following tables: master.sys.databases sys.sysprocesses sys.dm_os_sys_info sys.dm_os_ring_buffers msdb.dbo.backupset master.dbo.sysdatabases master..sysprocesses msdb..sysjobactivity sys.master_files sys.dm_tran_session_transactions sys.dm_os_sys_memory sys.database_files
Oracle DB tables and execute commands	Discovery credentials should have read access to: Run “lsnrctl services” and “sqlplus” commands dba_data_files table dba_segments table v$database table gv$instance table dba_hist_osstat table dba_hist_snapshot table v$asm_disk table v$asm_diskgroup table dba_audit_session table gv$session_longops table gv$session table gv$sqlarea table gv$process table
