Fragments

Fragments are similar to CRC Align Error packets with

 

the exception that each fragmented packet is less than

 

64 octets in length. This can indicate a high collision

 

rate.

Collisions

The number of collisions detected on the network.

 

Collisions are common phenomena on Ethernet

 

segments. Excessive collisions are detrimental to

 

network performance. It is an indication that you have

 

too many stations trying to communicate

 

simultaneously. If the situation persists, perhaps it′ s

 

time to consider further segmenting of your network.

Packet Size Statistics

The probe keeps individual counters for the

 

occurrences of packets with the following lengths:

10.4.1.2 History Group

The History group provides a means of correlating the data gathered by the Statistics MIB over time. It records statistical samples according to a user-specified time interval and duration and stores them for later retrieval.

The History MIB can be used to gather separate studies collected simultaneously from various probes and at different intervals. For instance, you can set up a session to collect statistical data via the Statistics MIB from several probes every 10 seconds for real-time monitoring. The History MIB can be configured to gather statistics from the same sources at intervals of 30 seconds for an ongoing portrait, and at 30-minute intervals for later study.

You are encouraged to set up two history control entries per monitored interface upon initialization. One can be set for short term polling at intervals of 30 seconds and another for long term polling at 30 minute intervals.

Each interval saved is referred to as a ″bucket″. The number of buckets to be used is defined by the operator. The interval can range from one second to one hour.

Note

It is important to configure the appropriate time interval for data sampling as no indication will be given when the statistical counters overflow their maximum value. For instance, on a heavily-loaded Ethernet segment, the etherHistoryOctets counter could overflow in about an hour. Following this, the information stored by this counter will not reflect the true state as it will reset to zero and start incrementing again. The maximum counter value of the RMON agent varies according to implementation and hardware architecture. On the RMONitor Agent for OS/2 device, the maximum counter value is 232.
