- Organization of this page
Function
The Device Detail (PD_DEV) record stores the performance data that shows the state of the file system driver and kernel driver devices at a given point in time. This is a multi-instance record.

A value between 0 and 32,767 seconds can be specified (a value within the range specified for Collection Interval). Use this item to distribute the collection load, because executing data collection all at once results in concentration of the processing workload. Note that the data collection duration to be recorded is the same as the Collection Interval, regardless of the value specified for Collection Offset.

Data source |
---|---|---|---|---|---|---|
Active (ACTIVE) |
Indicates whether the device was active during data collection. The following values are valid: - YES - NO |
-- |
string (8) |
No |
-- |
-- |
Depend Group Name (DEPEND_GROUP_NAME) |
List of group names that must be loaded before devices are loaded. If there is no group name that must be loaded, this field is left blank. |
-- |
string (256) |
No |
-- |
-- |
Depend Service Name (DEPEND_SERVICE_NAME) |
List of service names that must be loaded before devices are loaded. If there is no service name that must be loaded, this field is left blank. |
-- |
string (256) |
No |
-- |
-- |
Device Name (DEVICE_NAME) |
Device name. Name used by the user interface program to identify a device. |
-- |
string (256) |
No |
-- |
-- |
Device Type (DEVICE_TYPE) |
One of the following two device driver service types: - FILE_SYSTEM_DRIVER: File system's device driver service - KERNEL_DRIVER: Kernel's device driver service |
-- |
string (36) |
No |
-- |
-- |
Error Control (ERROR_CONTROL) |
Severity of the error that occurred during device service startup. The following values are valid. - CRITICAL: If possible, the starting program records the error in an error log. If the startup procedure used the normal configuration that was previously used, the startup fails. In other cases, use the normal configuration that was previously used to restart the system. - IGNORE: The starting program records the error in an error log and continues the startup operation. - NORMAL: The starting program records the error in an error log, displays a message in a pop-up box, and continues the startup operation. - SEVERE: The starting program records the error in an error log. If the startup procedure used the normal configuration that was previously used, the startup operation continues. In other cases, use the normal configuration that was previously used to restart the system. |

Group Name (GROUP_NAME) |
Group name in the group list that determines the loading order registered in the registry, to which this device belongs. If the device does not belong to any group, this field is left blank. |
-- |

No |
-- |
-- |
Image Path (IMAGE_PATH) |
Device image path name. If the device is not active, this field is left blank. If the image path name cannot be acquired because no information exists in the registry, this field is left blank. |
