This feature is a further extension of the History/Trend analysis and lets you view the graphical representation for a monitor across different servers in one unified chart. You can either see the Current trend analysis (shows the graph for last 1 hour) or the Historical trend analysis for a selected time-frame.
With the Current time-frame selected, the Trend graph icon is present just beside the monitor name. When clicking, it displays the trend graph of last 1 hour duration for the selected servers in the Monitors page. The selected servers list is displayed on the right hand side, the servers can be selected or unselected by clicking the server name.
This is similar to the Current trend graph, the difference being that you can select any desired time-frame for which you want to see the graph for. You can choose the time-frame as History and then click the Trend Graph icon beside the counter name to see the graph. Along with the graph, it also shows the values of the monitor in the tabular form. Enable the option Show Only Changed Values to check when the monitor value was changed.
