Agenda

• Overview• Installation• Topology• Console Overview• Q & A


Overview

• JBN EM is a monitoring and administration system Monitor and control JEMS, other products

• Server/agent architecture One server collecting data from agents running

on each monitored platform (hub-n-spoke model) Database persists inventory metadata, collected

metrics and alert information

• User interfaces JBN EM Console – a web-based GUI JBN EM CLI – an interactive command line shell Users/roles provide access control


Overview - Server

• A J2EE app with a Web GUI• Runs on Linux, Windows, Solaris, and HP/UX• Inventory

Physical and logical topology• Monitoring

Platforms, JEMS products extensible for future products

• Control Ad-hoc and scheduled

• Problem Resource Identification & Root Cause Baselines - a rolling snapshot of normal system behavior

• Events & Alerting • Security / Access Control

User/Roles SSL

• High Scalability Can be enabled for increased scalability


Overview - Agent

• Standalone Java app with small portions of portable C code in places where Java does not yet reach.

• Runs on Linux, Windows, Solaris, HP/UX, and AIX.• The agent has pluggable subsystems

Measurement Control Auto-discovery

• Plugin Layer Sits below the subsystems Subsystem delegates to plugin when a subsystem needs to interact

with a particular product (for example to gather a metric or restart a service).

Plugins can be added or removed as you decide which products you want to manage or ignore

• Fault Tolerant Agent continues to function normally even if the JBN EM server is

temporarily unavailable. Collected metrics will be spooled to disk. When the JBN server comes back online, the agent transmits all spooled data.

The configuration of each agent (which metrics it collects, what its control schedule is, and so on), is stored centrally at the JBN server. If an agent gets deleted from a platform for any reason, then nothing is lost. When the agent is reinstalled, it will download its configuration from the server and resume operations as if nothing had happened.


Installation

• UNIX Installation Download the appropriate server

installation package for your platform, run the setup script and answer the prompts

A basic install can be performed by executing “setup.sh –full” and choosing which components you want to install: the server, agent and/or shell


Installation

• Windows Installation Download the appropriate installation

package for your platform, run the graphical installer and follow the wizard

The installer allows you to choose which components you want to install: the server, agent and/or shell

A Windows Service will be installed for the server and agent so they can be started automatically

A Windows Service for the database will be installed if you elect to use the embedded database


Installation

• Database Embedded Postgres External Postgres External Oracle

• If you want the embedded Postgres, the installer will install it for you

• If you want to use an external database, you must install it separately


Installation


Installation

• Running on UNIX Use the .sh scripts

• jbn-server.sh• jbn-agent.sh• jbn-shell.sh

• Running on Windows Use the Windows Services to

start/stop the server and agent. jbn-shell.bat


Topology

• One or more host machines running one or more software products is known as your “topology of resources”. JBN EM can inventory your topology In the world of JBN EM, your “inventory”

includes only those resources that are to be managed

• JBN EM inventories your enterprise topology through its discovery mechanisms


Topology Nomenclature - Physical

• Inventory consists of one or more “resources”.

• A physical resource can be described generically as one of these types: Platforms

• The actual machines in your environment• Hosts “server” resources (see below)• One agent runs on each managed platform

Server• Product specific, such as a JBossAS instance or

an Apache Web Server.• Hosts “service” resources (see below)

Service• Individual components within a server• Examples are EJBs, JMS destinations


Topology Nomenclature - Logical

• You can logically group your physical resources Compatible Group

• Group of like resources (servers of type “JBoss 4.0”)

Mixed Group• Group of different types (platform, servers

and/or services) Auto Group Application

• Groups of services of different types


Populating Inventory

• JBN EM inventories your enterprise topology through its discovery mechanisms Auto-discovery

• Process table scan• Windows Registry scan

Manual• File scan

Auto-discovery scans can be scheduled Newly discovered resources can be

accepted (adding them to your inventory) or rejected (and thus ignored)


JBN EM Console Overview

• The Console is one of two interfaces for accessing the JBN EM functionality (the other being the CLI shell).

• Dashboard Aggregates various information into a single screen. Shows auto-discovery results

• Resource Browsing• Resource Views

Shows information on resources found in inventory Displays performance/health metrics Executes control actions on resources Allows you to configure and view alerts

• Administration JBN EM user and role management Access control definitions for both Console and CLI System configuration


Importing Discovered Resources

• Dashboard shows you resources that have been auto-discovered

• Select resources to import or reject• Importing resources tells JBN EM that

you want to manage those resources


Browsing Inventory List

• View the inventory list• Shows physical and logical resources• Manually add resources to inventory• Click on a resource to get its individual view


Resource View - Inventory

• Shows the inventory metadata for the resource. There are four categories: Type information (e.g. Tomcat 4.1, Tomcat 5.0) List of resources it contains (e.g. services in the server). List of resources which contain it (e.g. groups). Configuration information used by JBN EM (e.g. location

of run.bat for JBoss).


Resource View - Monitoring

• Shows metric values collected on a resource over time.

• Can view metric values in three ways: High-level chart (default). Detailed chart. Raw metric data.

• Can configure which metrics are actually collected and how frequently they are collected (called the “metric collection interval”).


Resource View - Control

• Allows execution of particular actions on a resource.• Only available for certain resources. Available actions

depend on resource type.

• Can view history of previously executed control actions.• Control actions can be executed immediately or scheduled

for later execution (may be recurring or non-recurring schedule).

schedule future actions

execute action now


Resource View - Alerts

• General mechanism for responding to events.• Alerts are triggered when specific conditions are met on:

One or more metric values, e.g. JVM Free memory. Control action status values, e.g. JBoss restart status.

• When an Alert is triggered: It is stored in the Alert History. (Optionally) an email can be sent to JBNEM users, JBNEM roles

or external email addresses. (Optionally) a control action can be executed. Alerts can be enabled or disabled individually or collectively.

alert definitions


Dashboard

• Aggregates many aspects from the Resource view.

• Most interesting portlets: Auto-Discovery Favorite Resources Recent Alerts Control Actions Problem Resources


Administration

• Allows you to define: JBN EM users and roles Access control Global server configuration settings


Help

• Documentation available online at:https://network.jboss.com/docs/jbnhelp/bin/view/JBN/Index.html

• Context sensitive help for each page is also available.

• Future WebEx presentations coming soon! Will demonstrate in more detail the features

provided by JBN EM Will hopefully be able to more completely

answer your questions

Thanks for your time!
