This database file lists the fields in the IOP extended data file.
Data is reported for the Network Server (*IPCS category) and I/O
adapters (*IOPBASE category). Network server data includes 
Integrated xSeries® Server
data and virtual I/O data. Virtual I/O data consists
of one record for each virtual device in use. If Network Server
is associated with a Network Server Host Adapter, virtual device might have
more than one record reported per interval--one record for each Network Server
Host Adapter, used by this virtual device. If concurrent maintenance
is done (adding or removing hardware under an IOP), the user should cycle
the collector to insure that I/O adapter data is reported correctly.
| Field Name | Description | Attribute |
|---|---|---|
| INTNUM | Interval number: The nth sample database interval based on the start time specified in the Create Performance Data (CRTPFRDTA) command. | PD (5,0) |
| DTETIM | Interval date (yymmdd) and time (hhmmss): the date and time of the sample interval. | C (12) |
| INTSEC | Elapsed interval seconds: the number of seconds since the last sample interval. For operating system data (data type 2), this value might not be the same as the change in the interval date and time (DTETIM) for the interval because the elapsed interval time comes directly from the Integrated xSeries Server . | PD (7,0) |

Note:
The following chart shows the types of counters used.
D (Delta counter): Number of occurrences in the interval (what most performance counters are).
S (State counter): The value at the time of collection or the maximum value during the interval.
