Statistics > RMON History
The RMON History screen contains information about samples of data taken from ports. For example, the samples may include interface definitions or polling periods.
Statistics > RMON History
The RMON History screen is divided into RMON History and Log Table.
Source Interface Displays the interface from which the history samples were taken. The possible field values are:
•• Port Specifies the port from which the RMON information was taken.
•• LAG Specifies the port from which the RMON information was taken.
Sampling Interval Indicates (in seconds) the time that samplings are taken from the ports. The field range is 1‑3600. The default is 1800 seconds (equal to 30 minutes).
Max No. of Samples to Keep Indicates the number of samples to save.
Owner Displays the RMON station or user that requested the RMON information. The field range is
The Add to List button adds the configured RMON sampling to the Log Table at the bottom of the screen.
