WebLogic Analyzer

The Applicare WebLogic Analyzer enables you to view and analyze WebLogic Server data over a selected timeframe. These analyzers give 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.

To launch Weblogic Analyzer:

1. Click Applicare WL > Applicare Analyzer > WebLogic Analyzer.  The WebLogic Analyzer window will appear.  To begin analyzing WebLogic data follow the following steps:

2. 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.

3. From the Server drop-down menu, select a server to analyze and click Go.  WebLogic Analyzer will generate four graphs displaying the state of the following data:

·         Queue Size can be used to detect queue expansion problems.  This graph is the one that responds to your mouse, driving the analysis.   

·         Server Throughput can be used to server performance issues.

·         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.

4. Place your mouse cursor in the Queue Size 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, represented by a small white square, which tracks the graphs as you move your cursor. This helps you pinpoint values in the monitored data displays at specific moments.  

5. 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.  This status line begins with the Time, and is followed by the Queue Size, Throughput, Waiters Count, and Heap Used.  

1. 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:

1. Move the left slider on the bar to establish the beginning portion of your timeframe analysis, using the Time displayed just above the sliders and bar as your guide.
2. Move the right slider on the bar to establish the ending portion of your timeframe analysis, using the Time displayed 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.
