The AutoPilot Composite Analyzer enables you to view and analyze WebLogic Server data, including the machine's CPU, over a selected timeframe. This analyzer gives you a dynamic graphical display that you can manipulate to examine the data from general views to more precise views to pinpoint system states.
This graphical analyzer also enables you to refresh the graphic display, zoom in and out of the displayed data from a general overview across the entire timeframe to more precise views of that timeframe, recall the previous and next zoomed data (similar to a browser's Back and Forward buttons), and navigate through the data panels.
Click AutoPilot WL > AutoPilot Analyzer > Composite Analyzer. The Composite Analyzer window will appear. To begin analyzing server CPU and WebLogic data follow the following steps:
Select a timeframe from the drop-down menu. The following options are available:
One Day Back
Today
Last 7 Days
Last 30 Days
Custom Date (see note below.)
Note: The Custom Date option is used in conjunction with the From: and To: fields. If you select Custom Date, you must click on the ellipsis (...) buttons next to the From and To fields to display a calendar. From this calendar, directly click on the dates corresponding to the beginning and end of the timeframe you want to analyze.
From the Server drop-down menu, select a server to analyze and click Go. The Composite Analyzer will generate four graphs displaying the state of the following data:
Server Throughput can be used to detect server performance issues.
Queue Size can be used to detect queue expansion problems.
Waiters Count can be used to detect database pool issues.
Heap Used (in MB) can be used to observe how much of the Java heap is being utilized by the JVM.
CPU Used Percent can be used to examine the server CPU activity.
Place your cursor in the Throughput panel to display a graphical timeline that responds to the movement of your mouse. Corresponding timelines relative to the displayed data in the other panels appear. Each timeline also contains a dynamic pointer that tracks the graphs as you move your cursor; this helps you pinpoint values in the monitored data displays at specific moments.
You can view the exact values of the current point on each of the graphs on the status line directly under the drop-down boxes from which you selected the timespan and server.
Just above the graphic display is a bar with two sliders that, when the graphs are first generated, are located at the ends of the bar. This bar and sliders enable you to examine the data in all panels as a percentage of the timeframe you selected from the drop-down box in Step One.
To adjust the precision of the data displayed in the graphs:
Move the left slider on the bar to establish the beginning portion of your timeframe analysis, using the Time displayed in the status line just above the sliders and bar as your guide.
Move the right slider on the bar to establish the ending portion of your timeframe analysis, using the Time displayed in the status line just under the sliders and bar as your guide.
The larger the percentage (the farther apart the sliders are on the bar), the more data is displayed in the graphs, giving a more general overview. The smaller the percentage, (the closer the sliders are to each other on the bar) the less data is displayed on the graphs, giving a more precise overview.
