To view I/O activity across all Ops Insights enabled databases, click I/O under Resources in the left navigation menu.

By default, you view comprehensive I/O activity for each database. Viewing the I/O activity for each database lets you compare resource utilization between databases and identify servers with underused or overused resources. For each database, you view the following:

• Database Types
  • ADW-D: Autonomous Data Warehouse Dedicated
  • ADW-S: Autonomous Data Warehouse Serverless
  • ATP-D: Autonomous Transaction Processing Dedicated
  • ATP-S: Autonomous Transaction Processing Serverless
  • External NonCDB: External Non-Container Database
  • External PDB: External Pluggable Database
  • Virtual Machine PDB: Virtual Machine Pluggable Database
  • Bare Metal PDB: Bare Metal Pluggable Database
  • ExaDB-D PDB: Exadata Database Service on Dedicated Infrastructure pluggable database
  • ExaDB-D NonCDB: Exadata Database Service on Dedicated Infrastructure non-container database
  Note
  
  ExaDBs monitored by Enterprise Manager are also allowed.
• Usage Change (%): Percentage change in the linear trend of I/O usage over the selected time period
• Usage (TB): 90th percentile value of the daily average I/O usage over the selected time period
• Allocation (TB): Allocation for the 90th percentile value of the daily average storage usage over the selected time period
• Database Version: Version of the Oracle Database.
• Telemetry: The source platform of the database: Cloud Infrastructure, Enterprise Manager, or Agent Service
• Instances: The number of instances. Click on the instance number to display a list of the instance and host names.

I/O charts analysis and usage are similar to those used elsewhere in the Capacity Planning application. For an in-depth discussion about Capacity Planning charts, see:
