Field Description
SampleIndex
Uniquely identifies a specific etherStats entry. The value range is 1 to 65535.
Utilization
If greater precision is required, you should sample the etherStstsPkts and etherStatsOctets objects before and after a common interval. The differences in the sampled values are Pkts and Octets, respectively. The number of seconds in the interval is Interval. These values are used to calculate the utilization as follows:
The result of this equation is the value Utilization, which is the percent utilization of the Ethernet segment on a scale of 0 to 100 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). You can use this object as a reasonable estimate of Ethernet utilization. For greater precision, sample the etherStatsPkts and etherStatsOctets objects before and after a common interval.
Pkts
The total number of packets (including bad packets, broadcast packets, and multicast packets) received.
BroadcastPkts
The total number of good packets received that were directed to the broadcast address. Note that this number does not include multicast packets.
MulticastPkts
The total number of good packets received that were directed to a multicast address. Note that this number does not include packets directed to the broadcast address.
DropEvents
The total number of events in which packets were dropped by the probe due to lack of resources. 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 total number of packets received that had a length (excluding framing bits, but including FCS octets) of between 64 and 1518 octets, inclusive, but had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error).
UndersizePkts
The total number of packets received that were less than 64 octets long (excluding framing bits but including FCS octets) and were otherwise well formed.
OversizePkts
The total number of packets received that were longer than 1518 octets (excluding framing bits but including FCS octets) and were otherwise well formed.
Fragments
The total number of packets received that were less than 64 octets in length (excluding framing bits but including FCS octets) and had either a bad Frame Check Sequence (FCS) with an integral number of octets (FCS Error) or a bad FCS with a nonintegral number of octets (Alignment Error). It is entirely normal for etherStatsFragments to increment because it counts both runts (which are normal occurrences due to collisions) and noise hits.
Collisions
The best estimate of the total number of collisions on this Ethernet segment.
