  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.htm • See: 2.0 TOI Materials and ASAP 2.0 TOI EDL • Questions => email: support@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

  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. ASAP EDL – Opening EDL IDE Window

  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. ASAP EDL – Working with EDL IDE Window

  14. EDL IDE – Rapid Application Development

  15. EDL IDE - Context Sensitive Help

  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 ATMSystem Atm Status Cash-------- ----- ------ ----\Chicago Loop Up 150\Chicago North Up 3750

  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 ATMSystem 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

  18. ASAP EDL - ATTRIBUTE statement • Attribute statements define entity columns • ENTITY ATM ...

  19. Value State ASAP EDL – “StatePairs” • 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 <Value> has a <State> associated with it • StatePairs form a ( <Value>,<State> ) 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.

  20. Value State ASAP EDL – “StatePair” Property • 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 ATMSystem 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

  21. ASAP EDL – Cash “StatePair” Example • DATA ATMSystem 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 • System • Atm • Status • Op • Date • Time • Cash • CashState

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

  23. Value Value is State Value State Value State ASAP EDL - “StateRule” Algorithms

  24. 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 ATMSystem 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

  25. 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...

  26. 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

  27. 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

  28. 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.
