This page provides an overview of RMON History entries. Each page shows up to 99 entries from the History
table, default being 20, selected through the "entries per page" input field. When first visited, the web page will
show the first 20 entries from the beginning of the History table. The first displayed will be the one with the
lowest History Index and Sample Index found in the History table.
The "Start from History Index and Sample Index" lets you select the starting point in the History table. Clicking
the Refresh button will update the displayed table starting from that or the next closest History table match.
The Next Entry will use the last entry of the currently displayed entry as a basis for the next lookup. When the
end is reached the text "
No more entries
" is shown in the displayed table. Use the First Entry button to start
over.
