SUMMARY
This article describes the relevance and some possible uses for the information in the Stats frame of a Network Monitor capture.



MORE INFORMATION
When you view a capture using Network Monitor, it is helpful to have additional statistics concerning the data that is captured. In Network Monitor, a Stats frame is added at the end of each capture. This frame contains relevant information concerning the capture. Although the overall contents can change depending on topology, one section that is consistently included is the Stats section.

The following example shows a Stats section of a Network Monitor capture:   STATS: Number of Frames Captured = 917 STATS: Bytes Left = 80 (0x50) STATS: Version = 0 (0x0) STATS: Elapsed Time = 4 Seconds 316 Milliseconds STATS: Total Frames Captured = 917 (0x395) STATS: Total Bytes Captured = 186342 (0x2D7E6) STATS: Total Frames Filtered While Capturing = 917 (0x395) STATS: Total Bytes Filtered While Capturing = 179006 (0x2BB3E) STATS: Total Frames Seen During Capture = 917 (0x395) STATS: Total Bytes Seen During Capture = 179006 (0x2BB3E) STATS: Total MultiCasts Received = 49 (0x31) STATS: Total BroadCasts Received = 847 (0x34F) STATS: Total Frames Dropped From Capture = 0 (0x0) STATS: Total Frames Dropped From Buffer = 0 (0x0) STATS: MAC Frames Received = 827 STATS: MAC CRC Errors = 0 STATS: MAC Bytes Received = 1662 STATS: MAC Frames Dropped due to No Buffers = 0 STATS: MAC Frames Dropped due to HardWare Errors = 0 STATS: MAC MultiCasts Received = 39 STATS: MAC BroadCasts Received = 776 Some of the more useful pieces of information include:
 * Number of Frames Captured

This value is helpful in determining if you are viewing a filtered capture. If this number does not match the number in the capture, the frames are filtered.
 * Elapsed Time

If this value is small and the Total Bytes Captured value is large, there may be possible throughput saturation on the network.
 * Total Frames Seen During Capture and Total Bytes Seen During Capture

If a capture filter is used, these values should indicate how much data is not included in the capture.
