6.3.8.3 Monitoring I/O Resource Management (IORM) Using Exadata Metrics

You can monitor I/O Resource Management (IORM) by using Oracle Exadata System Software metrics.

IORM uses the database unique name, not the database identifier, to collect statistics and display output. Starting with Oracle Exadata System Software release 19.1.0, if you configured ASM-scoped security for the Oracle Automatic Storage Management (Oracle ASM) cluster used by the database, then the database name is prefixed with the Oracle ASM cluster name.

• Monitoring IORM with Database Metrics
  Database metrics provide information about the I/O load from each database listed in the IORM interdatabase plan.
• Monitoring IORM with PDB Metrics
  Pluggable Database (PDB) metrics provide information about the I/O load from each PDB hosted by a container database (CDB) listed in the IORM interdatabase plan.
• Monitoring IORM with Consumer Group Metrics
  Consumer group metrics provide information about the I/O load from each consumer group specified in a database resource plan.
• Monitoring IORM with Category Metrics
  Category metrics provide information about the I/O load from each category specified in the current IORM category plan.
• Monitoring IORM Utilization
  You can use metrics to monitor IORM utilization.
