DB IOPS & Throughput from AWR report Oracle DB

Detailed I/O Metrics and Network Throughput

The AWR report provides more granular I/O and network metrics, often summarized in an "I/O Profile" or found within "Instance Activity Stats."

I/O Profile (Summary):

  • IOPS: Total Requests: Read + Write Per Second

  • Throughput (MB): Total (MB): Read + Write Per Second

Mapping from "Instance Activity Stats" to "IO Profile":

Instance Activity Stats Metric

IO Profile Metric (Per Second)

physical read total IO requests

Total Requests: Read per Second

physical write total IO requests

Total Requests: Write Per Second

physical read total bytes / 1024 / 1024

Total (MB): Read per Second

physical write total bytes / 1024 / 1024

Total (MB): Write Per Second

Mapping from "Load Profile" to "Instance Activity Stats":

Load Profile Metric

Instance Activity Stats Metric

Read IO requests

physical read IO requests

Write IO requests

physical write IO requests

Read IO(MB)

physical read bytes

Write IO(MB)

physical write bytes

Network Throughput:

These metrics provide insight into network activity related to SQL*Net communication.

  • bytes received via SQL*Net from client

  • bytes sent via SQL*Net to client

  • MB received via SQL*Net from client

  • MB sent via SQL*Net to client
