  1. JBoss Network Enterprise Manager Introduction and Walkthrough The Professional Open Source™ Company

  2. Agenda • Overview • Installation • Topology • Console Overview • Q & A 2 The Professional Open Source™ Company

  3. 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 3 The Professional Open Source™ Company

  4. 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 4 The Professional Open Source™ Company

  5. 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. 5 The Professional Open Source™ Company

  6. 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 6 The Professional Open Source™ Company

  7. 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 7 The Professional Open Source™ Company

  8. 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 8 The Professional Open Source™ Company

  9. Installation 9 The Professional Open Source™ Company

  10. 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 10 The Professional Open Source™ Company

  11. 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 11 The Professional Open Source™ Company

  12. 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 12 The Professional Open Source™ Company

  13. 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 13 The Professional Open Source™ Company

  14. 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) 14 The Professional Open Source™ Company

  15. 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 15 The Professional Open Source™ Company

  16. 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 16 The Professional Open Source™ Company

  17. 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 17 The Professional Open Source™ Company

  18. 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). 18 The Professional Open Source™ Company

  19. 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”). 19 The Professional Open Source™ Company

  20. 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). execute action now schedule future actions 20 The Professional Open Source™ Company

  21. 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. click here for alert history click here to define new alert definitions 21 The Professional Open Source™ Company

  22. Dashboard • Aggregates many aspects from the Resource view. • Most interesting portlets: • Auto-Discovery • Favorite Resources • Recent Alerts • Control Actions • Problem Resources 22 The Professional Open Source™ Company

  23. Administration • Allows you to define: • JBN EM users and roles • Access control • Global server configuration settings 23 The Professional Open Source™ Company

  24. 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. Go to online help Context sensitive help 24 The Professional Open Source™ Company

  25. Q & A • 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! 25 The Professional Open Source™ Company
