Network Interface Overview (PI_NETI)
- Organization of this page
Function
The Network Interface Overview (PI_NETI) record contains performance data collected at certain intervals, such as the rate of data and packets transferred over a connection such as a TCP/IP connection, and the number of various types of errors that occurred over each connection.
This is a multi-instance record.
- Notes:
-
-
In an environment that uses both IPv4 and IPv6, consolidated IPv4 and IPv6 information is collected.
-
If the approximate bandwidth of an interface exceeds 4,294,967,295 bits per second, information for this interface is not displayed correctly, because this value exceeds the range of values that can be displayed in the Current Bandwidth field of the PI_NETI 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.

Instance (INSTANCE) |
Instance name for the network. The instance name is a loopback address (127.0.0.1), NIC, or dial-out WAN wrapper for each device. It is displayed in the order of TCP/IP protocol binding (loopback is always the first) as follows: - Driver name for NIC |

RECORD_TIME (T1) - RECORD_TIME (T0) |
Interval2 (INTERVAL2) |
Collection interval during which the record was stored (seconds). For a real-time report, the first value is 5. If records are summarized into a historical report, the total of the summarized records is displayed. |
