JMX Overview


JMX
-

Java Management Extensions


Technology for managing and monitoring
networks, systems, applications, and services


Provides tools for building modular and dynamic
managing and monitoring solutions


Cross
-
platform Alternative to SNMP


Uses Java classes called MBeans to expose mgmt
interface of the managed devices


JMX Manager

JMX Overview…


Benefits of JMX


Scalability


Compatibility


Implementation Cost


Where is it used?


web phones to set
-
top boxes to network devices
and servers


Who uses JMX?


IBM, HP, AdventNet, Sun, Tomcat, Oracle


J2EE vendors such as: JBoss, Enhydra, Weblogic


JMX Architecture (3 Layers)


Manager Level


Link between mgmt application and
JMX agent


Making integration possible


Where JMX Manager resides



Agent Level


Contains JMX agents


Has 2 components: MBean Server &
Agent Services



Instrumentation Level


Defines manageable resources


Has 3 components

Architectural Components

(Instrumentation Level)


MBeans (Managed Beans)


central blocks of the instrumentation level


Makes resources manageable by defining characteristics and
processes


Employs dynamic class loading


Notification Model


Can be manipulated to send critical messages


Similar to SNMP Trap


MBean Metadata Classes


Defines MBean components (i.e. attributes, operations, etc…)


Also contains names, description, characteristics, etc…


Architectural Components

(MBeans)


Standard MBean


Java objects that conform to certain design pattern


Simpler and quicker to implement


Mgmt interfaces, operations, & attributes are static


Method names describe the mgmt interface.


Best used for setting up new manageable resources



Dynamic MBean


Generic methods are used for setting/getting attributes


Mgmt interfaces exposed at run time


Quite complex to implement


They can be used to access non
-
Java native resources

Architectural Components

(MBeans)


Model MBean


Fully configurable and self describe at run time


It’s an MBean template because it uses generic,
configurable MBean classes


Gives managers additional info about managed
resources such as runtime & behavioral data.


Open MBean


self defining and portable


Can be managed by non
-
Java based mgmt
application.



Architectural Components

(Agent Level)


MBean Server


Repository of MBeans


Involved in the MBean registration


Agent Services


customizable objects


Dynamic Class Loader


can load new
classes from any network location


Monitors


Observes changes


Timers


Scheduling mechanism


Relation Services


defines relationship
between MBeans

JMX Connectors and
Protocol Adapters


Remote Monitoring with JMX Connectors


Create point to point communication


Consists of 2 components


Connector Server


Connector Client


Connector Heartbeats


Protocol Adapters


Provides view of an agent and its MBeans thru different
protocols.


Accessing Non

Java Programs


Software components residing on the server/managed devices
