Viewing history
Ethernet history records periodic statistical samples from a network. A sample is
called a history and is gathered in time intervals referred to as “buckets.”
Histories establish a time-dependent method for gathering RMON statistics on a
port. The default values for history are:
• Buckets are gathered at 30-minute intervals.
• Number of buckets gathered is 50.
Both the time interval and the number of buckets is configurable. However, when
the last bucket is reached, bucket 1 is dumped and “recycled” to hold a new
bucket of statistics. Then bucket 2 is dumped, and so forth.
To view RMON history:
1 From the Device Manager main menu, choose RMON > Control > History
1 Select an RMON entry.
2 On the toolbar, click Graph.
The RMON graph Port dialog box opens displaying the Interface tab.
3 Click the RMON tab.
The RMON tab opens (Figure 111).
