Promiscuous History
The History Control Table (Figure 5-12) presents the configuration of each
History instance running on the network interface. By default, the RMON
standard specifies 2 instances, having intervals of 1800 seconds and 30
seconds. Each instance features the following fields:
• Data Source—Interface being monitored.
• Interval—The sample collection interval.
• SizeReq—Maximum number of recorded intervals (buckets) requested
for the sample
• Size—The number of buckets correctly recorded in the sample.
•Owner—The person who configured the entry.
• Status—The status of the control table entry.
Note that when the values for SizeReq and Size are identical, the oldest
entries in the History Control Table for that instance will be replaced by the
newest entries.
Viewing the History Table
Double click any Promiscuous History Control Table entry to display the data
for that instance. The History Table shows the past performance measured at
the monitored network interface (data source) of the device. Appendix B
contains detailed descriptions of the fields found in the History Table.
