Use Physical Disk attributes to create situations that monitor information about fixed and hard disk drives. Physical disk is a multiple-instance attribute group. You cannot mix these attributes with those of any other multiple-instance group.
% Disk Idle Time The percentage of elapsed time that the selected disk drive is not servicing any read or write requests. Valid values are positive integers in the range 0 to 100 (expressing a percentage).
% Disk Read Time The percentage of elapsed time a disk drive 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 a disk drive has been busy servicing read or 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 12%, enter 12.
% Disk Write Time The percentage of elapsed time that a 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 7.5%, enter 7.5.
Avg Disk Bytes/Read The average number of bytes transferred from a disk per read operation. Valid values are positive integers in the range 0 to 2147483647 (expressing bytes per read) and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 2,000 bytes read, enter 2000.
Disk Bytes/Sec The rate at which bytes are transferred to or from a 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 2,000,000 bytes per second, enter 2000000.
Disk Name The name of a physical disk. Valid format is a text string of up to 64 characters.
Disk Queue Length The number of requests outstanding on a disk the instant the data is collected, including requests currently in service. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *AVG, *MIN, *MAX, or *SUM functions. For example, to express 512 for the number of requests outstanding on a disk, enter 512.
Disk Read Bytes/Sec The average number of bytes read from a disk per second. Valid values are positive integers in the range 0 to 2147483647 (expressing bytes/second) and can include the use of the *MIN, *MAX, or *SUM functions. For example, to express 2,000,000 bytes per second, enter 2000000.
Disk Reads/Sec The average number of read operations that have occurred on a disk per second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *MIN, *MAX, or *SUM functions. For example, to express 430 for the number of read operations occurring on a disk, enter 430.
Disk Transfers/Sec The average number of read and write operations that have occurred on a disk per second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *MIN, *MAX, or *SUM functions. For example, to express 230 for the number of read and write operations per second occurring on a disk, enter 230.
Disk Write Bytes/Sec The average number of bytes written to a disk per second. Valid values are positive integers in the range 0 to 2147483647 (expressing bytes/second) and can include the use of the *MIN, *MAX, or *SUM functions. For example, to express 2,000,000 bytes written per second, enter 2000000.
Disk Writes/Sec The average number of write operations that have occurred on a disk per second. Valid values are positive integers in the range 0 to 2147483647 and can include the use of the *MIN, *MAX, or *SUM functions. For example, to express 327 for the average number of write operations occurring on a disk, enter 327.
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.
