Generic JMX client using RMI or IIOP Protocols

To set-up the monitoring of a generic JMX client, right-click the Monitored Application icon > KM Commands > New > Java MBean polling (JMX) and select the Generic environment from the drop-down list:

WIZ_JavaMBeanPolling_1GenericWelcome

Java MBean Polling Wizard (Generic Environment) — Welcome Page

The application server should be started with the option: -Dcom.sun.management.jmxremote.port=portNumber
Using the above option starts a dedicated JMX agent for this particular application. The Monitoring Studio generic JMX client needs to use this port number to establish a connection.

Step 1: Enter the generic environment connection information

WIZ_JavaMBeanPolling_2GenericConnectionInfo

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

•	Host: Name of host server where the generic JMX application server is installed.

•	Port: Enter the port number.

•	Server name: Enter the server name

•	Protocol: Select the relevant protocol: RMI / IIOP

Step 2: Enter the connection account credentials:

WIZ_JavaMBeanPolling_3GenericCredentials

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

•	Principle: Enter the username

•	Credentials: Enter the password

•	Path to Java on the local server: Enter your java bin 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.

Step 3: Select domain

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

WIZ_JavaMBeanPolling_4GenericDomain
Java MBean Polling Wizard (Generic Environment) — Domain Selection Page

1.	Select the domain to monitor

2.	Choose the key property selection mode. You can either choose to select a key property among a list of existing ones or type a regular expression for the key property name.

3.	Click Next.

Step 4: Specify the key property

Depending on the option selected at the previous step, you will either have to select a key property among a list of existing ones or type a key property name (regular expression).

Step 5: Select the attribute

WIZ_JavaMBeanPolling_6GenericAttribute

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

Select the attribute to monitor 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 (Generic 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

You arrive at the final step of the wizard that displays the object display name, ID and threshold options. For more information, refer to the section Configuring the Monitoring Studio Settings.

Click Finish. An icon for the monitored instance will appear under the main Monitoring Studio icon 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.

Generic JMX application objects are instances of the SW_JMX class.
