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 http://NonstopASAP.com/Document.htmhttp://NonstopASAP.com/Document.htm –See: 2.0 TOI Materials and ASAP 2.0 TOI EDL –Questions => email: support@NonstopASAP.comsupport@NonstopASAP.com
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 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 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 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 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 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 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

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

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 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 2 2000/11/15 10:00 150 7 \Chicago North Down 8 2000/11/15 10:00 3750 2 ASAP EDL – “StatePair” Property ValueState

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 ASAP EDL - “StateRule” Algorithms Value Value is State ValueState ValueState
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 2 2000/11/15 10:00 150 \Chicago North Down 8 2000/11/15 10:00 3750
