The following information is provided:
Field | Description |
---|---|
Access | Attempts: the percentage of optimization attempts (opimization attempts divided by total number of commands). |
Type | Successes: the percentage of successful optimization attempts (successful optimization attempts divided by number of optimization attempts). |
Read-Ahead | Attempts: the number of read-ahead optimization attempts, and the attempt percentage (read-ahead optimization attempts divided by total number of commands). Successes: the number of successful read-ahead optimization attempts, and the percentage of successful attempts (successful read-ahead optimization attempts divided by read-ahead optimization attempts). |
