  • EM12c Metric Extensions Designing, Deploying and Dynamic Success Kellyn Pot’Vin Sr. Techical Consultant
  • Kellyn Pot’Vin  Westminster, Colorado  Oracle ACE, Sr. Technical Specialist at Enkitec  Specialize in performance and management of large enterprise environments.  Board of directors for RMOUG, Director of Training Days 2013 and Database Track Committee for KSCOPE 2013  Blog:  Twitter: @DBAKevlar
  • Why We Monitor our Databases  Pro-active notification of issues before resulting in outages/impact to users.  Awareness of performance, resource usage and demands.  Data collection to investigate performance issues- current, recent and historical.  Capacity planning.
  • Monitoring and Notification Downfalls Yahoo News- “Over 70% of workers would give up shower[ing] to eliminate unnecessary emails.”     Paging with “Successful” and/or “I’m OK”. Not alerting for enough types of failures, instead covering with when complete. Paging on “Warning” Setting Critical thresholds too high vs. giving time to correct.
  • When Extend Current Monitoring?  Specialized or proprietary applications could benefit from monitoring and alerting.  EM12c is all about adaptive and selfservice.  Effective Monitoring of all mission-critical systems allows the business to be proactive saving it time, resources and money.
  • Why Not Enhance User Defined Metrics?  No Library to store and view.  No development cycle support, (dev testdeploy)  Lack of versioning.
  • Presentation Agenda  Metric     Extensions The Basics The How The Types The Reasons
  • Rules vs. Metric Thresholds • Rule are Set Globally. • Rules are Independent of Database Metric Settings.
  • What Are Metric Extensions?     A dynamically configured extensions feature allowing to monitor environment specific conditions. Simplifies monitoring of operational processes that once only existed outside of the EM12c console. Eliminates requirements for secondary monitoring and management tools. Eliminate need for external scripting that may require more monitoring logic than EM Jobs can provide.
  • Metric Extensions Details      Metric Extensions replace the formerly known “User Defined Metrics” User Defined Metrics were limited to database and host types, no longer with Metric Extensions. Ability to build a metric extensions library to utilize for your own environment. Full development cycle support Using specific protocols , the Oracle Integration Adapter gathers data about targets for use with metrics extensions.
  • Metric Extension “Verbage”  Metric Extensions Use the following:  Target Type- Required to tell the metric what “tools” will be required to monitor.  Adapter- The type of “communicator” required to execute the metric extension.  Collection Frequency- Interval settings to collect the information.  Columns- Returned data from output and metric value settings.
  • Metric Extension Types          Host Level Java, including Jboss, JVM, OC4J, etc. Metadata Repository OMS- OMS, Repository, Platform Oracle Access Managers Oracle BI Oracle Exadata system and components Oracle HTTP and Weblogic server And others….
  • Metric Determines the Adapter Depending on the type of Target, the Adapter used by the Metric Extension Changes…  Java- JMX(Java Mgmt Extensions/OS Cmds  Cluster Database- OS Cmd/SQL  Apache HTTP Server- OS CMD
  • The “More” of Metric Extensions    A simple wizard allows for easy development and refinement of metric extensions. Ability to test metrics using the “Test Page” allows an ability to run real-time metric evaluations to ensure definitions and scripts are free of errors before deploying. Loved, stand-alone scripts, with small changes can become metric extensions, too!
  • Development Life Cycle
  • Enterprise > Monitoring > Metric Extensions
  • First Step, General
  • OS Scripting, 2 Ways
  • Creating Your Own Script
  • Setting Input and Environment Variables
  • Adding Custom Files  For more complex metric extensions, you can upload parameter files, support files, etc.
  • The Right Panel Display Additional Info
  • Adding Columns  The output of the report will decide the layout and type of columns:
  • Column and Thresholds  The Percentage Used of Temp will be Returned as part of the script, anything over 10 will alert a warning, anything 25 in this column will alert critical.
  • Choose a Target
  • Credentials  Choose a pre-existing setup or new?
  • Completed Creation, Now Test!
  • Testing o Testing can be done as many times as necessary. o A full explanation of any failure is shown in the “Error Message” Window. o A full log of the tests are retained in the Metric Extensions Testing History.
  • The Finale!  Test, rinse, and repeat, (deploy/publish!)  Only publish once you are satisfied that all testing was performed adequately.
  • Check_Temp Library Bound!
  • Publishing/Deploying/Retaining
  • Things to Remember    No Metric Extension is active UNTIL it is deployed. Just because a metric extension is in the library, does not mean that it is ready to deploy and should always be tested before deployment. You are deploying the metric extension to the target, so if you are using a script, the script will need to be on the (remote) target.
  • EM CLI and Metric Extensions Metric Extension Verbs export_metric_extension -- Export a metric extension to an archive file get_unused_metric_extensions -- Get a list of unused metric extensions import_metric_extension -- Import a metric extension archive file publish_metric_extension -- Publish a metric extension for use by all administrators save_metric_extension_draft -- Save a deployable draft of a metric extension
  • Make it Easy on Yourself  emcli help <verb> is your friend… 
  • Metric Extensions Summary  Create development metric extension, wizard will simplify process.  Test with test page and verify that all steps, all features of the metric extension test correctly.  Deploy to target separately or to groups.  Utilize to fulfill any missing areas in monitoring environment.

  • Who: You and the world’s leading authorities on Exadata, all in one place. What: Two days of deep diving into the internals of all things Exadata — providing the tools and knowledge you need to fully harness its advanced powers. When: E4 will be held on August 5-6, 2013; 8:00 a.m. to 5 p.m. each day. Where: Four Seasons Hotel & Resort, Irving, Texas, AND Online Why: Because Exadata machines everywhere want to be fully understood and appreciated.
