Graph Port History
| Item | Description |
|
| SampleIndex | An index that uniquely identifies the particular sample this entry represents among all samples associated with the same historyControlEntry. This index starts at 1 and increases by one as each new sample is taken. |
| Utilization | The best estimate of the mean physical layer network utilization on this interface during this interval, in hundredths of a percent. |
| Octets | The total number of octets of data (including those in bad packets) received on the network (excluding framing bits but including FCS octets). |
| Pkts | The number of packets (including error packets) received during this sampling interval. |
| BroadcastPkts | The number of good packets received during this sampling interval that were directed to the broadcast address. |
| MulticastPkts | The number of good packets received during this sampling interval that were directed to a multicast address. Note that this number does not include packets addressed to the broadcast address. |
| DropEvents | The total number of events in which packets were dropped by the probe due to lack of resources during this interval. Note that this number is not necessarily the number of packets dropped, it is just the number of times this condition has been detected. |
| CRCAlignErrors | The number of packets received during this sampling interval that had a length (excluding framing bits but including FCS octets) between 64 and 1518 octets, inclusive, but were not an integral number of octets in length or had a bad Frame Check Sequence (FCS). |
| UndersizePkts | The number of packets received during this interval that were less than 64 octets long (excluding framing bits but including FCS octets) and were otherwise well formed. |
| OversizePkts | The number of packets received during this interval that were longer than 1518 octets (excluding framing bits but including FCS octets) but were otherwise well formed. |
| Fragments | The total number of packets received during this sampling interval that were not an integral number of octets in length or that had a bad Frame Check Sequence (FCS), and were less than 64 octets in length (excluding framing bits but including FCS octets). |
| Collisions | The best estimate of the total number of collisions on this Ethernet segment during this interval. |
