Plotting Server Performance
The Plot Server feature enables you to view a graphical representation of the performance
history for any server.
To plot the a server’s performance history:
1. Log into the Equalizer Administration interface with view or edit access.
2. In the left frame, click the name of the server whose history you want to view.
3. Select Plot Server History from the local menu in the Server Parameters frame. The
graphical history for the selected server is displayed.
By default, the active connections, service time, computed load, and dynamic weight
are plotted for the previous five minutes. To change the information plotted, select the
categories and duration you want to plot and click the Plot button.
To zoom in on a portion of the graph, click the area that you are interested in.
Five values can be plotted for a server:
■
Active connections —the number of active connections on the server. The connection
count is “smoothed” using a sliding-window smoothing algorithm before being
plotted. Note that the number of active connections on a server will be higher if you
have the sticky timer enabled.
