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.

Bytes Rcvd/sec (BYTES_RECEIVED_PER_SEC)

Rate at which data was received through the network interface (bytes/second).

Bytes Sent/sec (BYTES_SENT_PER_SEC)

Rate at which data was sent through the network interface (bytes/second).

AVG

Bytes Total/sec (BYTES_TOTAL_PER_SEC)

Rate at which data was sent/received through the network interface (bytes/second).

AVG

Current Bandwidth (CURRENT_BANDWIDTH)

Estimated network interface bandwidth (bits/second). If the bandwidth was stable or an accurate bandwidth estimate could not be obtained, the field shows an estimated nominal bandwidth (bits/second).#

AVG

ulong

No

--

--

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

COPY

Interval (INTERVAL)

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 last stored value is displayed.

COPY

ulong

No

--

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.

ADD

ulong

No

--

RECORD_TIME (T1) - RECORD_TIME (T0)

Output Queue Length (OUTPUT_QUEUE_LENGTH)

Length of the outbound packet queue (number of packets). This field always shows 0 because the NDIS (Network Driver Interface Specification) puts the requests in the queue.#

AVG

ulong

No

--

--

Pkts Outbound Discarded (PACKETS_OUTBOUND_DISCARDED)

Number of outbound packets selected for discarding by emptying the buffer area, even though no error preventing transmission was detected following the OS startup.#

ulong

No

--

--

Pkts Outbound Errors (PACKETS_OUTBOUND_ERRORS)

Number of outbound packets that could not be transmitted due to an error following the OS startup.#

AVG

ulong

No

Pkts Rcvd Discarded (PACKETS_RECEIVED_DISCARDED)

Number of received packets selected for discarding by emptying the buffer area, even though no error preventing transfer to an upper-layer protocol was detected following the OS startup.#

Pkts Rcvd Errors (PACKETS_RECEIVED_ERRORS)

Number of received packets containing an error preventing transfer to an upper-layer protocol following the OS startup.#

AVG

ulong

No
