Capture window: Total Statistics pane

The Total Statistics pane provides an overall view of network traffic sent to or from the local computer. This pane appears in the upper-right corner of the Capture window, and it is on by default.

Network Statistics

The total amount of traffic that has been sent to or from the local computer since the current capture began. These statistics include:

The total number of frames sent to or from the local computer.
The total number of broadcasts sent to or from the local computer.
The total number of multicasts sent to or from the local computer.
The total number of bytes sent to or from the local computer.
The total number of frames dropped.
The network status. On an Ethernet network, this entry will always be Normal. On a token ring network, this entry reflects whether the token is present locally.

Captured Statistics

Total statistics that describe the current capture, including:

The total number of captured frames.
The total number of frames in the temporary capture file.
The number of frames dropped when the buffer was exceeded.
The total number of captured bytes.
The total number of bytes in the temporary capture file.
The percentage of allotted buffer space that is in use.
The number of frames dropped by Network Monitor.

Per Second Statistics

Statistical averages of current activity and continual updates of this average to reflect current per-second activity. The statistics in this panel include all frames (even frames that were excluded by a capture filter). Per-second statistics include:

The average number of frames per second detected since the capture began.
The average number of bytes per second detected since the capture began.
The average number of broadcast messages per second detected since the capture began.
The average number of multicast messages per second detected since the capture began.
The percentage of network utilization. This statistic shows the percentage of your network adapter's capacity that the current capture uses. This percentage is calculated by dividing the rate at which your adapter is sending and receiving frames by the maximum rate at which your adapter can process those frames.

Network Card (MAC) Statistics

Statistics that reflect average activity detected by your network adapter since the current capture began. The statistics in this pane reflect all the network activity that your network adapter can receive. These statistics include:

Total frames detected by the network adapter.
Total broadcast frames detected by the network adapter.
Total multicast frames detected by the network adapter.
Total bytes detected by the network adapter.

Network Card (MAC) Error Statistics

Statistics that reflect adapter-related errors that have occurred since the capture began. These statistics include:

Number of errors that occurred because the cyclical redundancy check (CRC) did not match the actual bytes received.
Number of frames that the network adapter detected but that were dropped because Network Monitor lacked sufficient buffer space.
Number of frames that the network adapter detected but that were dropped because of hardware constraints.

Note

Not all network adapters support these statistics. If your network adapter does not support a statistic, the value is replaced with Unsupported.
