- Records written — The number of records (notes) written to the AI file.
- Bytes written — The amount of AI data written to the AI file, in bytes.
- Busy buffer waits — The number of times a process had to wait because a buffer was held.
- Buffer not avail — The total number of times a process had to wait because a buffer was not available.
- Partial writes — The number of writes to the AI file made before the AI buffer is full. This might happen if:
