Figure 31. Add RMON Group 2 Control Entry Window.
You are required to enter some information, which describes how to collect statistics for reporting:
1.The desired Interface Number.
2.The Owner String to identify the entry owner (not required);
3.Number of Buckets: the requested number of discrete time intervals over which data will be collected. It is actually the number of samples. Values greater than 50 are not recommended. When the number of buckets reaches its maximum value, the oldest bucket is deleted and a new bucket added.
4.Interval: the time period in seconds over which the data is sampled for each bucket. This interval can be set to any number between 1 and 3600 (1 hour).
Press OK in the Add RMON Group 2 Window. If the Create operation fails, it may mean that RMON Group 2 is not supported on this device.
You may use the Delete button in the RMON Group 2 Window (Figure 30) in order to delete the undesired control entry.
The History Table contains history information for one interface. This information corresponds to the currently selected control entry in the History Control Table (see above). In order to change an entry (interface), click on the desired entry in the History Control Table. After data retrieving, the History Table fills with the corresponding information. Every History Table line corresponds to one sample (bucket) and includes the following information:
1.Time: The start time of the interval over which the sample was measured.
2.Octets: The total number of octets received by the interface during the specified interval.
3.Packets: The total number of packets received by the interface during the specified interval.
4.Utilization: The interface utilization, in percents.
5.Errors: The total number of error packets received by the interface during the specified interval.
