Logical Drive Detail

% Disk Read Time

Percentage of time the disk was busy when a read request was processed (%).

% Disk Write Time

Percentage of time the disk was busy when a write request was processed (%).

% Free Space

Free disk space as a percentage of the total usable area (%).^#1

Avg Disk Bytes/Read

Average number of bytes transferred from the disk during read operations (bytes/process).

Avg Disk Bytes/Write

Average number of bytes transferred to the disk during write operations (bytes/process).

Avg Disk Read Queue Length

Average number of read requests that have entered the disk queue.

Avg Disk Secs/Read

Average time for reading data from the disk (seconds).

Avg Disk Secs/Write

Average time for writing data to the disk (seconds).

Avg Disk Write Queue Length

Average number of write requests that have entered the disk queue.

Current Disk Queue Length

Number of requests remaining in the disk that are waiting to be processed or currently being processed. Normally if the queue length continues to exceed 2, it indicates processor congestion.^#1

Disk Read Bytes/sec

Speed at which data is transferred to the disk during read operation (bytes/second).

Disk Reads/sec

Disk read processing speed (bytes/second).

Disk Write Bytes/sec

Speed at which data is transferred to the disk during write operation (bytes/second).

Disk Writes/sec

Disk write processing speed (bytes/second).

Disk Xfers/sec

Disk read and write processing speed (bytes/second).

Free Mbytes

Free disk space as part of the total usable area (MB).^#1

ID

Logical disk volume name. Example: C: or D:

Page File Size Mbytes
