Description

This command can be used to configure the settings of the JMX Monitoring subsystem.

Options

asadmin-options

Options for the asadmin utility. For information about these options, see the asadmin help page.

--help

-?

Displays the help text for the subcommand.

--target

This option helps specify the target on which you are configuring the JMX monitoring service. Valid values are:

server: Applies to the default server instance. This is the default value.
cluster_name: Applies to every server instance in the cluster.
instance_name: Applies to a specified server instance.

--enabled

Defaults to false. Enables or disables the JMX monitoring service

--dynamic

Defaults to false. When set to true, applies the changes without a server restart.

--amx

Defaults to false. Whether to enable or disable the AMX subsystem on boot.

--addAttribute

Provides a way to add a new MBean attribute to monitor using the service.

This argument takes in a string of space-delimited key-value pairs corresponding to the values of a JMX MBean definition. The attributeName and objectName fields are required, but description is not.

For example, providing attributeName=HeapMemoryUsage denotes that the name of the MBean attribute to log is HeapMemoryUsage, while objectName=java.lang:type=Memory denotes the ObjectName of the MBean to look for the attribute on is java.lang:type=Memory.

--delAttribute

Provides a way to remove an MBean attribute that is being monitored by the JMX Monitoring service.

Use the name of the attribute that you want to remove from the monitoring output.

--logFrequency

Defaults to 15. The frequency that the service will use to periodically log monitoring entries.

--logFrequencyUnit

Defaults to SECONDS. The time unit to set the frequency of the log done by the JMX Monitoring service.

--set-notifiers

Use the option to set the notifiers that will receive notifications generated by the JMX Monitoring service.

A comma-separated list can be used to represent multiple notifiers.

This option will replace all the notifiers that have already been set to the JMX Monitoring Service.

--enable-notifiers

Use the option to enable one or more notifiers for the JMX Monitoring service.

A comma-separated list can be used to represent multiple notifiers.

--disable-notifiers

Use the option to disable one or more notifiers for the JMX Monitoring service.

A comma-separated list can be used to represent multiple notifiers.

Examples

Example 1 Enables JMX monitoring service along with the AMX subsystem

asadmin set-jmx-monitoring-configuration --enabled=true --dynamic=true --amx=true --target=server

Example 2 Enables JMX monitoring service and monitors the amount of used Heap memory of the server’s JVM

asadmin set-jmx-monitoring-configuration --addAttribute 'attributeName=HeapMemoryUsage.used objectName=java.lang:type=Memory' --enabled true

Example 3 Enables JMX monitoring service and configures the logging frequency to 5 minutes

asadmin set-jmx-monitoring-configuration --logFrequency 5 --logFrequencyUnit MINUTES --enabled true

Exit Status

0: subcommand executed successfully
1: error in executing the subcommand
