4.2.3.6 RMON History Status
This page provides an detail of RMON history entries; screen in Figure 4-2-3-6 appears.
Figure 4-2-3-6: RMON History Overview Page Screenshot
The page includes the following fields:
Object Description
• History Index Indicates the index of History control entry.
• Sample Index Indicates the index of the data entry associated with the control entry.
• Sample Start The value of sysUpTime at the start of the interval over which this sample was
measured.
• Drop The total number of events in which packets were dropped by the probe due to lack of
resources.
• Octets The total number of octets of data (including those in bad packets) received on the
network.
• Pkts The total number of packets (including bad packets, broadcast packets, and multicast
packets) received.
• Broadcast The total number of good packets received that were directed to the broadcast address.
• Multicast The total number of good packets received that were directed to a multicast address.
CRC Errors 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 non-integral number of octets (Alignment Error).
• Undersize The total number of packets received that were less than 64 octets.
• Oversize The total number of packets received that were longer than 1518 octets.
• Frag. The number of frames whose size is less than 64 octets received with invalid CRC.
• Jabb. The number of frames whose size is larger than 64 octets received with invalid CRC.
• Coll. The best estimate of the total number of collisions in this Ethernet segment.
• Utilization The best estimate of the mean physical layer network utilization on this interface during
this sampling interval, in hundredths of a percent.
