Function
The Generic Data Interval (PI_GENI) is a user record that stores user-defined performance data per unit time. Because this record can store only the specific performance data rather than all performance data of the collection target object, it can reduce overhead and disk usage.
Depending on the performance data type, data is stored in one of the following two fields:
- Double (DOUBLE_DATA)
- String Data (STRING_DATA)
This is a multi-instance record.
- Notes:
- If the collection target instance specified by the collection data addition utility does not exist, a record whose Data Type (DATA_TYPE) field value is blank and that contains no performance data is created.
- This record is not suitable for collecting the performance data of an instance when instances having the same name are frequently created and disappear. Of the instances specified as collection targets by the collection data addition utility, if those with the same name are frequently created and disappear within the same data collection interval, these separate instances are treated as the same instance, and as a result, correct performance data cannot be collected.
- For the instances to be specified as collection targets by the collection data addition utility, do not specify instances with the same name that can concurrently exist.
When multiple instances specified as collection targets specified by the collection data addition utility have the same name (#n is added to the Instance (INSTANCE) field of the Generic Data Detail (PD_GENI) record), if one or more of them disappear, the performance data on the remaining active instances with the same name may become corrupt.
Also, when instances having the same name are newly generated, the performance data on the remaining active instances having the same name may become corrupt.
- If collection records are added by the collection data addition utility during a collection interval, 0 is displayed for the initial performance value for a record for which a performance value is computed from the information collected during the previous collection interval.
- When a user record is specified in a Windows Server 2003 (x64) or 64-bit version of Windows Server 2008 environment, objects that do not support WOW64 are not displayed in the PI_GENI-PD_GEND Record Settings dialog box of the collection data addition utility
