Disk attributes

The Disk attributes refer to disk characteristics such as inode size, inodes used, mount point, and space available. Only mounted file systems are monitored by this agent. Entries for the Disk Information table (UNIXDISK) reports file systems of the following types:

File System Status The availability status of the remote file system (NFS). Note: the value 2 indicates Up, 1 indicates Down, 0 indicates Not Available, and -2 indicates Not Collected.

File System Type The filesystem type name, for example jfs and gpfs. Values that include up to eight letters or numbers are valid. Note: the value -1 indicates Not Available and -2 indicates Not Collected. Any query, applied to an agent prior to V6.2.3, containing this attribute displays a blank in the File System Type column.

Inodes Available Percent The percentage of inode space currently not in use. Note: the value -1 indicates Not Available and -2 indicates Not Collected.

Inodes Free The number of inodes currently available on your file system. Use this attribute to avoid a pending crisis. Corrective action might include freeing up unneeded space or deleting temporary files. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 9223372036854775807 indicates Value_Exceeds_Maximum, and -9223372036854775808 indicates Value_Exceeds_Minimum.

Inodes Free (Superseded) The number of inodes currently available on your file system. Use this attribute to avoid a pending crisis. Corrective action might include freeing up unneeded space or deleting temporary files. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 2147483647 indicates Value_Exceeds_Maximum, and -2147483648 indicates Value_Exceeds_Minimum.

Example: Disk inode space is usually a high number, so the percentage of inode space to disk space must also be a high number. If the value for Inodes Free is less than 100, this is a critical condition. Notify your system administrator immediately. If the value for Inodes Percent is above 30%, delay taking corrective action.

Inodes Used The number of inodes currently allocated to files on the file system. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 9223372036854775807 indicates Value_Exceeds_Maximum, and -9223372036854775808 indicates Value_Exceeds_Minimum.

Inodes Used (Superseded) The number of inodes currently allocated to files on the file system. This value equals the Inode Size value minus the Inodes Free value. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 2147483647 indicates Value_Exceeds_Maximum, and -2147483648 indicates Value_Exceeds_Minimum.

Inodes Used Percent The percentage of inode space currently allocated to files. Valid entries are whole numbers up to 100, such as 85 for 85%. Note: the value -1 indicates Not Available and -2 indicates Not Collected.

Mount Point The path name of the directory to which a file system is mounted. This is the virtual name for the directory. Valid entries are up to 32 letters or numbers representing a directory path.

Mount Point (Unicode) The path name of the directory to which a file system is mounted. This is the virtual name for the directory.

Name The name of the physical disk partition where the file system is mounted. This is the physical location of the disk. Valid entries are up to 32 letters or numbers.

Name (Unicode) The name of the physical disk partition where the file system is mounted. This is the physical location of the disk.

Size (KBytes) The total size of a file system, expressed in kilobytes with 64 bit precision. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 9223372036854775807 indicates Value_Exceeds_Maximum, and -9223372036854775808 indicates Value_Exceeds_Minimum.

Note: the value -1 indicates Not Available, -2 indicates Not Collected, 9223372036854775807 indicates Value_Exceeds_Maximum, and -9223372036854775808 indicates Value_Exceeds_Minimum.

Space Available (KB) (Superseded) The amount of unused space currently available to non-superusers on a file system, expressed in kilobytes. For example, 40000 represents 40 megabytes. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 2147483647 indicates Value_Exceeds_Maximum, and -2147483648 indicates Value_Exceeds_Minimum.

This disk space does not include any space which is reserved for supersuser. A low value in this column, relative to the disk size, alerts you to critical disk space conditions.

If this value is low for one or more file systems, relative to the disk size, you might need to evaluate reconfiguring the file system to distribute the files more evenly across disks.

System Name The managed system name. The form should be hostname:agent_code.

Examples include spark:KUX or deux.raleigh.ibm.com:KUX.

In workspace queries, this attribute should be set equal to the value $NODE$ in order to populate the workspace with data. This attribute is generally not included in situations, unless there is a need to customize the situation for a specific managed system.

Timestamp The date and time the agent collects information as set on the monitored system. The timestamp for SCAN and STR functions is in the CYYMMDDHHMMSSmmm format (as in 1020315064501000 for 03/15/02 06:45:01) where:

C

= Century (0=20th)

YY

= Year

MM

= Month of the Year (01-12)

DD

= Day of the Month (01-31)

HH

= Hour, in 24-hour time (00-23)

MM

= Minute

SS

Total Inodes The number of inodes allocated on a file system. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 9223372036854775807 indicates Value_Exceeds_Maximum, and -9223372036854775808 indicates Value_Exceeds_Minimum.

Total Inodes (Superseded) The number of inodes allocated on a file system. For example, a value of 163817 indicates that the number of inodes allocated is 163,817. Note: the value -1 indicates Not Available, -2 indicates Not Collected, 2147483647 indicates Value_Exceeds_Maximum, and -2147483648 indicates Value_Exceeds_Minimum.

Use this attribute when a file system needs additional or fewer inodes assigned to it. Viewing the current number of inodes assigned helps you determine the number of inodes you need to add or subtract to optimize performance in your system.
