Logical Disk Attributes

Use Logical Disk attributes to create situations that monitor information about disk drive partitions that have been assigned a drive letter. Logical disk is a multiple-instance attribute group. You cannot mix these attributes with those of any other multiple-instance group.


% Disk Read Time The percentage of elapsed time a logical disk has been busy servicing read requests. Valid values are positive integers in the range 0 to 100 (expressing a percentage) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 85%, enter 85.

% Disk Time The percentage of elapsed time that a logical disk has been busy servicing read and write requests. Valid values are positive integers in the range 0 to 100 (expressing a percentage) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 23%, enter 23.

% Disk Write Time The percentage of elapsed time that a logical disk drive has been busy servicing write requests. Valid values are positive integers in the range 0 to 100 (expressing a percentage) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 15%, enter 15.

% Free The percentage of the volume that is free space. Valid values are positive integers in the range 0 to 100 (expressing a percentage) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 21%, enter 21.

% Used The percentage of the volume that is used. Valid values are positive integers in the range 0 to 100 (expressing a percentage) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 25%, enter 25.

Avg Disk\ms/Read The average amount of time for a read of data from a logical disk. Valid values are positive integers in the range 0 to 2147483647 (expressing milliseconds) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.

Disk Bytes/Sec The rate at which the system has transferred bytes to and from a logical disk during write or read operations. Valid values are positive integers in the range 0 to 2147483647 (expressing bytes/second) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 800 bytes/sec, enter 800.

Disk Name The name of a logical disk. Valid format is a text string of up to 64 characters.

Disk Queue Length The number of requests outstanding on a logical disk. This number includes requests in service when the data is collected. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.

Disk Read Bytes/Sec The rate at which the system has transferred bytes from a logical disk during read operations. Valid values are positive integers in the range 0 to 2147483647 (expressing bytes/second) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 800 bytes/second, enter 800.

Disk Reads/Sec The rate of read operations from a logical disk. Valid values are positive integers in the range 0 to 2147483647 (expressing reads/second) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 5 reads/second, enter 5.

Disk Transfers/Sec The rate of read and write operations on a logical disk. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.

Disk Write Bytes/Sec The rate at which the system has transferred bytes to a logical disk during write operations. Valid values are positive integers in the range 0 to 2147483647 (expressing bytes/second) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 600 bytes/second, enter 600.

Disk Writes/Sec The rate of write operations to a logical disk. Valid values are positive integers in the range 0 to 2147483647 (expressing writes/second) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 5 writes/second, enter 5.

Free Megabytes The number of megabytes of unallocated space on a logical drive. Note: One megabyte = 1,048,576 bytes. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.

Server Name The name of the managed system. Valid format is a text string of up to 64 characters.

Timestamp The date and time the Tivoli Enterprise Monitoring Server samples the data. Standard 16-character date/time format (CYYMMDDHHMMSSmmm), where:

C

Century (0 for 20th, 1 for 21st)

YY

Year

MM

Month

DD

Day

HH

Hour

MM

Minute

SS

Second

mmm

Millisecond

Use simple text strings as described above. For example, enter 0971009130500000 to express October 9, 1997, 1:05:00 pm.

Total Size The total size of the logical disk. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions.
