WebLogic server9.2 diagnostic framework-custom management view

Weblogic server console

The WebLogic Server. x console is a lightweight portal application (light weight Portal) system based on Struts. It is also a graphical tool for WebLogic domain management. However, sometimes the functions provided by the Management Console cannot meet our management needs. Therefore, Bea provides an Extension Mechanism for the Management Console, this allows you to cut, personalize, and expand features on the Weblogic server console as needed.

Wldf console Extension

Bea provides a management console extension for wldf (WebLogic diagnostic framework: Weblogic diagnostic framework)-wldf console extension (wldf-Ce. WLDF-CE provides a series of visualization tools to analyze diagnostic data.

Note: WebLogic Server 9.x and later provide this function

Requirements for WLDF-CE installation environment

1. BEA WebLogic 9.x
2. Meet the requirements of Weblogic server console browsers
3. Java Plug-in version 1.5
4. Open Java and Javascript in the browser

Install WLDF-CE

1. Copy the diagnostics-console-extension.jar from the % bea_home %/weblogic9x/Server/lib/console-ext/directory (if it is a Chinese version, also copy the diagnostics-console-extension-zh_CN.jar) to the % domain_home %/console-ext directory, if this directory does not exist, create it manually.
2. Restart WebLogic Server

View:Mainly responsible for creating, modifying, and deleting management views

Specifications:Tree display of all runtime mbean types, instances, and attributes

Request:Tree display of measurement event data

Attribute:Change chart attributes

View

Chart 5 View

The WLDF-CE provides many built-in views, for example, if we want to view runtime information about JMS (for example, how many messages are sent and how many messages are successfully sent), We can click on the jvmruntime view.

Of course, we can also combine our own views, which are called custom views. For example, if we want to display the JVM information and application deployment information in a view, we can customize the view for this requirement.

View panel

Chart 6 view panel

When you click View, you can view the charts in the view panel. A view can have multiple charts, you can drag the related runtime mbean to generate a chart or right-click the view panel to generate a chart.

Specification

The specification contains all mbean information on the server, including type, instance, and attribute. To view any mbean information, you only need to drag it to the view panel to view it in the form of a chart.

Request

Chart 7 Request

The request is mainly to display the collector collection data (harvester collection) of the diagnostic framework and the instrumentation data (instrumentation data) in the view panel as a chart.

Attribute

The attribute here mainly refers to the chart attributes. We can use this Management Panel to modify any chart attributes on The View. Commonly Used attributes include: collection interval, color used, chart type (bar chart, bar chart, etc.), axis name, and so on.

Conclusion: the Weblogic server console provides us with an open environment. We can customize the console extension as needed, and Bea also provides us with a wldf for weblogic) the extension of the console makes the management of WebLogic Server more user-friendly, convenient, and fast, and is another powerful tool for administrators.
