2 2 ASAP EDL - Contents  Overview of ASAP EDL Language –Why its important to understand EDL. –Requirements and Benefits –Interactive Development Environment –Statements and Examples  ASAP Resources –Internet –See: 2.0 TOI Materials and ASAP 2.0 TOI EDL –Questions =>

3 3 ASAP EDL - Overview  What is EDL ? –Defines how a monitored Entity is related to ASAP features and functions.  Developers use EDL –To define how to monitor Subsystem Availability –To define how to monitor Application Availability  EDL is not something that ASAP users –Need to see, –Understand, –Or even be aware of…

4 4 ASAP EDL – Why care about EDL?  EDL was designed to define entity & availability properties  But EDL resulted in additional benefits: –Allows users to have different sets of customized ASAP settings. –Allows entire environments to be archived for later reference. –Observed behavior can be shared with other ASAP users. –ASAP environments can be mailed to other people. –Useful for Application and System reporting.  Both Data and Schema are stored in an EDL file: –Allows an entire ASAP environment to be saved in EDL file. –Means you can completely snapshot or capture situations. –EDL Files can be saved, mailed, reviewed, and displayed.  To better understand EDL, let’s review EDL Requirements

5 5 ASAP EDL – Requirements  ASAP R2 Requirements…  Needed to allow extensible Entity Definitions –Allow Customers to define different Application Entities. –Allow Third Parties & EMFs access to Application Entities.  Needed to provide an entity-attribute Name-Space –Allow DOTs to use entity-attribute Names, instead of metric id#s. –Allow users to customize entity-attribute Names (internationalization)  Needed to reduce Maintenance –Provide Version Independent code (R2 Client runs against R1 Server) –Reduce Source Code maintenance (Add new Entity w/o code change)

6 6 ASAP EDL – Requirements  Needed to Externalize Definition & Customization of –Entity Names –Attribute Names –Help Text –Heading Text –Availability Vectors –Data Integrity Checks –State Determination Rules –Graph Normalization Values –Data Formatting & Alignment –Command required to retrieve data –… –and any other ASAP property that is related to Entity-Attribute definitions.

7 7 ASAP EDL - Features  Result - Entity Definition Language (EDL) File  EDL File provides “Container” for ASAP properties  EDL File allows ASAP properties to be “Portable”. –Provides Portable encapsulation of ASAP Properties. –Entities, Attributes, and Data can be “moved around”. –You can save/share different ASAP environments. –Client registers the.EDL extension with Windows.  EDL also provides mechanism for: –Version independence - due to encapsulation. –Problem Reporting - Captures entire environment. –Prototyping – Entity, Attribute, Data definitions. –Education – Demo features of environment. –QA/Testing - Reproducing test scenarios.

8 8 ASAP EDL – Benefits  EDL Allows Applications to use full ASAP infrastructure. –Release 1.0 supported multiple applications  But only allowed one stats record definition for all Apps.  All entity Metrics were forced into single record model.  Restrictive, and lead to Nonhomogeneous data. –Release 2.0 allows multiple entity definitions  Allows separate Statistics record definition for each entity.  Allows different Apps to have different entity-attribute names.  Allows named service-level objectives, eg Rank ATM, Cash>1000.  Allows disjoint Applications & Third Parties to share infrastructure.  Allows specific user inclusion/exclusion of App entities... Atm, Funds, Accounting

9 9 ASAP EDL – Getting Started with EDL  EDL Development Environment –Accessed from ASAP Client –Select File... pulldown Menu –EDL menus are initially disabled. Protects inexperienced users

10 10 ASAP EDL – Enabling EDL IDE -EDL not enabled by default -To enable EDL IDE -Select View... Options... -Select Entity Tab -Click EDL Button [...] -Check EDL-IDE check box -Click OK -File... EDL... pulldown menus will now be enabled

11 11 ASAP EDL – Opening EDL IDE Window

12 12 ASAP EDL – IDE  ASAP Interactive Development Environment –Allows Entity definitions to be interactively developed –Allows Rapid Prototyping of Entities and Data –Allows Importing and Exporting of EDL definitions –Provides on-the-fly editing and compilation of entity definitions –Provides context sensitive Help for statements

13 13 ASAP EDL – Working with EDL IDE Window

14 14 EDL IDE – Rapid Application Development

15 15 EDL IDE - Context Sensitive Help

16 16 ASAP EDL - Statements  ENTITY statement –Defines entity name and properties (eg SQL Table) –ENTITY Atm Help “Automated Teller Machine”  ATTRIBUTE statement –Defines entity attribute names and properties (eg SQL Columns) –ATTRIBUTE System Help “System Name” ATTRIBUTE Atm Help “Atm Name” ATTRIBUTE Status Help “Atm Status” ATTRIBUTE Cash Help “Cash in Atm”  DATA statement –Defines data associated with entity –DATA ATM System Atm Status Cash \Chicago Loop Up 150 \Chicago North Up 3750

17 17 ASAP EDL - ENTITY statement  Entity statement defines entity properties  ENTITY ATM Enabled YES Command "APP \* ATM,RAW,TAB,STATE“ Help "Automated Teller Machine“ KeyForNode System KeyForObj Atm KeyForRow “Date Time”;  DATA ATM System Atm Status Op Date Time Cash \Chicago Loop Up /11/15 10: \Chicago North Down /11/15 10:

DATA ATM System Atm Status Op Date Time Cash CashState \Chicago Loop Up /11/15 10: \Chicago North Down /11/15 10:

20 20 ASAP EDL - ATTRIBUTE statement syntax  Attribute statement defines attributes and properties  ATTRIBUTE Align LEFT | RIGHT Format Graph GraphMax Grid Heading HeadPickup Help MetricRule StatePair StateIsOp StateRule TypeData INT | INT32 | INT64 | REAL64 | CHARnn

21 21 ASAP provides the concept of StatePair Availability Vectors. StatePairs allow a state to be associated with an attribute value. When an attribute is defined to be a State Pair The Attribute has a associated with it StatePairs form a (, ) Pair Examples (98, 7) => Value=98, State 7 => Critical (“Up”, 2) => Value=“Up”, State 2 => Up Useful for assigning a state to a value, regardless of the value. ValueState ASAP EDL – “StatePairs”

22 22  In EDL “StatePair” indicates a state is paired with an attribute.  StatePair YES, says an attribute has a state associated with it.  State of attribute is determined by the value following Attribute.  AT Status GRID YES -- Show Annotated Status in Grid GRAPH YES –- Analysis & Graph Property StatePair YES –- Attribute is a State Pair vector StateRule UseStateGraphState –- State algorithm StateIsOp YES –- State is Operational object state HELP "Operational Status of Object"; AT OpState HELP "Operational State of Object";  DATA ATM System Atm Status Op Date Time Cash CashState \Chicago Loop Up /11/15 10: \Chicago North Down /11/15 10: ASAP EDL – “StatePair” Property ValueState

23 23 ASAP EDL – Cash “StatePair” Example  DATA ATM System Atm Status Op Date Time Cash CashState \Chicago Loop Up /11/15 10: \Chicago North Down /11/15 10:  System  Atm  Status  Op  Date  Time  Cash  CashState

24 24 ASAP Availability Vectors are not necessarily StatePairs in EDL. Availability Vector States are based on one of three constructs: Attribute is a Attribute a simple number such as: Transaction Rate, …. Attribute Value is a Attribute Value is interpreted as a 2 =>Up, 6 =>Warning, 7 =>Critical, 8 =>Down, … Attribute has Associated with it: StatePair Attribute is a (, ) Pair (“OK”, 2) => Value=“OK”, State 2 => Up (98, 7) => Value=98, State 7 => Critical Value Value is State ValueState ASAP EDL – “Availability Vectors”

25 25 ASAP EDL - “StateRule” Algorithms Value Value is State ValueState ValueState

26 26 ASAP EDL - DATA statement  Data statement allows entity data to be defined and saved in EDL file along with entity properties.  Data statement is useful for: –Saving data in an EDL file (eg for running environment) –Manually prototyping data for an entity (eg for design) –Displaying data in saved EDL file (demo/reporting).  DATA ATM System Atm Status Op Date Time Cash \Chicago Loop Up /11/15 10: \Chicago North Down /11/15 10:

27 27 ASAP EDL - DATA statement syntax  Data statement allows Entity data to be defined and saved in an EDL file along with entity properties. DATA Heading1 Heading2 Heading \Col1dat Col2Data Col3Data ;  WYSIWYG design layout makes DATA statement easy to use.  What-you-see-is-what-you-get Syntax is useful for both: –Designing prototype data for a new entity –Viewing generated EDL Data when using the EDL Export Function...

28 28 ASAP EDL – Exporting EDL  ASAP Client allows Exporting environment. –When you select File... Export EDL... –Client creates EDL for its Environment.  Exported EDL includes: –All Entity & Attributes Definitions –All Live Data for enabled entities –All Availability, Stats, & Performance data for enabled Objects and associated states –All Attribute settings including:  Show in Graph  Show in Grid  Graph Max values  State Determination Rules  To Export, select File... Export EDL... From ASAP Client browse window...

29 29 ASAP EDL – Export EDL - Options Dialog  Export EDL – Dialog defines what to export –System Entity Definitions  Cpu, Disk, Expand, File, Process, RDF, Spooler, System, Tape, TMF,... –User Entity Definitions  App, Atm, Funds, Accounts,... –Data Statements  Data for selected entities, eg Cpu, Disk,...  Click OK – To Generate & Export EDL

30 30 ASAP EDL – Exported EDL - IDE Window  When EDL is Exported to IDE Window  Exported EDL can be: –Edited –Compiled –Saved –Mailed –Imported –Re-compiled  Note EDL includes DATA statements  Represents Snapshot of the entire ASAP environment

31 31 ASAP EDL – Summary  Provides Extensible definition of Entities & Attributes –EDL Import - Allows Entities to be added. –EDL Export - Allows Environment to be captured.  EDL File - Provides a Container for ASAP properties –Allows ASAP properties to be Portable. –Encapsulates Entity, Attribute, and Data definitions. –Allows Saving and Sharing of ASAP environments.  EDL Provides: –Version Independence - due to encapsulation. –Problem Reporting – entire environment is captured. –Separation of statistics records - for Application entities. –Discrete entity-attribute names for Service Level Objectives. –Rapid Prototyping of Entity, Attribute, and Data definitions.  Allows Customers & Third parties to share ASAP Infrastructure.
