WebLogic

BEA WebLogic is a J2EE Platform product family that includes a J2EE application server- WebLogic Server, an Enterprise Portal - WebLogic Portal, an Enterprise Application Integration platform, a Transaction Server and Infrastructure - WebLogic Tuxedo, a Telecommunication Platform - WebLogic Communication Platform and also an HTTP web server for Unix, Linux, Microsoft Windows, and more.

To monitor your WebLogic application server within your PATROL environment, you first need to download certain WebLogic JAR files/zipped files from the Sentry Software download page and place them into: %PATROL_home%/bin.

The files required by WebLogic9.x are different from those required for WebLogic 8.x. Please ensure you download the correct files corresponding to your WebLogic server version.

WebLogic v8.x was created using JDK v1.4; therefore to run and poll WebLogic 8.x, you need to run JVM v1.4. No other JVM version will be able to run WebLogic 8.x.
WebLogic v9.x was created using the JDK v1.5, you need JVM v1.5 and above to connect to this server.

Right-click the main Monitoring Studio icon > KM Commands > New > Java MBean polling (JMX) From the drop-down list, select the environment: WebLogic "x"

WIZ_JavaMBeanPolling_1WebLogicWelcome

Java MBean Polling Wizard (WebLogic Environment) — Welcome Page

Step 1: Enter the server connection information and the additional information

WIZ_JavaMBeanPolling_2WebLogicConnectionInfo

Java MBean Polling Wizard (WebLogic Environment) — Connection Information Page

Host: Name of host server where the WebLogic application server is installed.

Port: Port number. (By default: 7001). Can be modified

For WebLogic 9.x:

•	Initial context factory: weblogic.jndi.WLInitialContextFactory (by default). Can be modified

•	JNDI: weblogic.management.mbeanservers.domainruntime (by default). Can be modified

For WebLogic 8.x

•	Initial context factory: weblogic.jndi.WLInitialContextFactory(by default). Can be modified

•	Server name (optional): Enter the server name

Step 2: Enter the connection account credentials

WIZ_JavaMBeanPolling_3WebLogicCredentials

Java MBean Polling Wizard (WebLogic Environment) — Connection Account Credentials Page

Principle: Enter the username

Credentials: Enter the password

Path to Java on the local server: Enter your java home path and ensure that all the settings are correct.

Connection timeout period: Default is set to 120 seconds; you can change this if you wish. When this timeout is reached, Monitor Studio considers the host to be unreachable and triggers an alert on the ExecutionStatus parameter.

Click Next. If the credentials entered are correct, Monitoring Studio connects to the application server and presents a list of domains for you to select from.

Step 3: Select the domain

WIZ_JavaMBeanPolling_4WebLogicDomain

Java MBean Polling Wizard (WebLogic Environment) — Domain Selection Page

Select the domain to monitor and click Next.

Step 4: Select the key property

WIZ_JavaMBeanPolling_5WebLogicKeyProperty

Java MBean Polling Wizard (WebLogic Environment) — Key Property Page

Select the key property to monitor from this domain and click Next.

Step 5: Select the attribute

WIZ_JavaMBeanPolling_6WebLogicAttribute

Java MBean Polling Wizard (WebLogic Environment) — Attribute Selection Page

Select the attribute from the list and click Next.

You can only select one attribute at a time. To monitor several attributes of the same key property, you are required to go through the wizard each time.

Step 5a: Select parameters to collect

When you select a numeric attribute (boolean, integer, number) at the previous step, an additional panel is displayed to allow you to select the parameters to collect.

WIZ_NumericValue_6Param

Java MBean Polling Wizard (WebLogic Environment) — Parameters Selection Page

▪	Value: Reports the actual value collected upon data polling

▪	Delta: Calculates the difference between values collected during two consecutive polling.

▪	DeltaPerSecond: Reports the value resulting of the division of the Delta by the number of seconds elapsed between the collection times

•	Select the option "Discard negative Delta values" if you do not want negative values to be reported on the graph.

•	Use the Rescaling option to configure Monitoring Studio to rescale the value that is being extracted in order to have a more readable graph in the PATROL Console. The available rescaling options are:

▪	No rescaling

▪	Divide the value by a value that then gives you the reading in terms best suited to you

▪	Multiply the extracted value by a constant factor

This can be useful if you extract numeric values in bytes but prefer to show a graph in megabytes. In such a case, you would divide the values by 1048576 (1024*1024).

Step 6: Monitoring Studio settings

WIZ_JavaMBeanPolling_7WebLogicSettings

Java MBean Polling Wizard (WebLogic Environment) — Settings Page

Object display name: Label displayed in the PATROL Console for this WebLogic monitoring.

Object internal identifier (ID): PATROL internal identifier.

What thresholds do you want to set for the newly created instance? A drop-down list allows you to select the mode of setting alert thresholds:

•	Use default thresholds: Uses the default thresholds set by Monitoring Studio

•	Set custom thresholds: Allows you to customize the thresholds for all parameters of the instance

•

Use default thresholds and customize them: Sets the default Monitoring Studio thresholds on certain parameters (see list of parameters with default thresholds) and then allows you to customize any/all of them. This is mainly intended to help save time if you wish to customize the thresholds of just one of many parameters for the instance, and leave the default settings for the others.

If you select Use default thresholds and customize them; on clicking Finish, the Set Thresholds panel will appear, certain parameters for the instance may appear with an asterisk symbol - indicating that they already have thresholds. You can then customize (any/all) the thresholds of the parameters as per your specific needs.

•	Do not set any thresholds for now: No thresholds will be set on any parameter of the instance, and as a result no alerts will be triggered. Monitoring Studio will poll the object and return the output of the polling – but will not raise any alerts until you set thresholds.

Thresholds can be set or modified at anytime by right-clicking on the instance > KM commands > Set Thresholds.

Click Finish. An icon for the monitored instance will appear under the main Monitoring Studio icon bearing the name entered/displayed in the Object display name field; and at the next collect you will see values for the newly monitored object. You can add a string or numeric value search if you wish.

WebLogic objects are instances of the SW_JMX class.
