The RMON History Group allows you to sample and archive Ethernet statistics for a
specific interface during a specific time interval. History sampling is done per port.
Note: RMON port statistics must be enabled for the port before an RMON History
Group can monitor the port.
Data is stored in buckets, which store data gathered during discreet sampling
intervals. At each configured interval, the History index takes a sample of the current
Ethernet statistics, and places them into a bucket. History data buckets reside in
dynamic memory. When the switch is re-booted, the buckets are emptied.
Requested buckets are the number of buckets, or data slots, requested by the user
for each History Group. Granted buckets are the number of buckets granted by the
system, based on the amount of system memory available. The system grants a
maximum of 50 buckets.
You can use an SNMP browser to view History samples.
The type of data that can be sampled must be of an ifIndex object type, as
described in RFC 1213 and RFC 1573. The most common data type for the History
sample is as follows:
1.3.6.1.2.1.2.2.1.1.<x>
The last digit (x) represents the number of the port to monitor.
