Performance Monitors

The performance monitors provide daily statistics captured by external HTTP pings, internal query server pings, and by summarizing the query transaction volume. Each set of statistics can be viewed as a graph by selecting one of the radio buttons, a date, and clicking on the button 'Graph It'.
NOTE: Filtered transactions do NOT include the internal health check hits in the volume totals. Thus, they represent hits from the public.

The Summary Statistics of the Search Transaction Volume is a monthly statistic that requires selection of the Summary Month and Year. The default is the current month.

The options below provide daily statistics: in all cases, a radio button and date below must be selected. The default date is the current day. In some cases, the individual query servers can be selected (via checkboxes) to be graphed separately. The query servers, nlquery1 (also called welch) and nlquery2 (also called shetland) are load balanced. If the checkboxes are not selected, the default is to show data from both servers on the graph. The final option under each section combines the datasets together in one graph.
