JBoss

JBoss is an open source Java EE-based application server implemented in Java. As the JBoss Application Server is 100% pure Java, it is interoperable with most operating systems that are capable of running a Java Virtual Machine (JVM); including Red Hat Enterprise Linux, SUSE Linux, Microsoft Windows, Sun Solaris, HP-UX, and others.

To monitor your JBoss AS within your PATROL environment, right-click the main Monitoring Studio icon > KM Commands > New > Java MBean polling (JMX) and from the drop-down list, select the environment: JBoss 3.2.x or 4.x.

WIZ_JavaMBeanPolling_1JBossWelcome

Java MBean Polling Wizard (JBoss Environment) — Welcome Page

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

WIZ_JavaMBeanPolling_2JBossConnectionInfo

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

JBoss connection information:

▪	Host: Name of host server where the JBoss application server is installed

▪	Port: JBoss port number. (1099 by default). Can be modified

JBoss additional information:

▪	Initial context factory: org.jnp.interfaces.NamingContextFactory (by default). Can be modified

▪	URL package prefixes: org.jboss.naming:org.jnp.interfaces (by default)

Can be modified

Step 2: Enter the connection account credentials

WIZ_JavaMBeanPolling_3JBossCredentials

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

Connection account:

▪	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. You can choose to execute additional JAR files by clicking the External JAR files button and enter the JAR files names and locations.

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_4JBossDomain

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

Select the domain to monitor and click Next.

Step 4: Select the key property

WIZ_JavaMBeanPolling_5JBossKeyProperty

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

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

Step 5: Select the attribute

WIZ_JavaMBeanPolling_6JBossAttribute

Java MBean Polling Wizard (JBoss 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 for each attribute.

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 (JBoss 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_7JBossSettings

Java MBean Polling Wizard (JBoss Environment) — Settings Page

Object display name: Label displayed in the PATROL Console for this JBoss 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 in the Console bearing the name entered/displayed in the PATROL Label 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.

JBoss objects are instances of the SW_JMX class.
