Presentation Provides Overview of– Availability Monitoring Concepts– ASAP Features, its Architecture– Release 2.0 Functions

ASAP Resources– White Paper & Migration Guide on TUT CD– Manuals on TIM Independent Products CD– IntraNet http://spg.web.tandem.com/ASAP– InterNet http://nonstop.compaq.com/view.asp?PAGE=OpsMgmt_ASAP

Before discussing ASAP– It’s important to understand, Why Monitor Availability?– It’s because monitoring increases actual Availability.– To understand why, first discuss Availability concepts.

Scenario - Person needs Taxi

– Has No Cash... so needs ATM

– Assumes ATM will be Available:

– Availability has many dependencies:

Right Card.. Valid Pin.. Remember Pin.. No Line.. Atm Up.. Network Up.. Routers Up.. Server Up.. Application running.. Account valid.. Balance OK.. Atm $ ?

Card?

Up?

Line?

Pin?Network?

Is a Relative NotionIs a Relative NotionIs a Relative NotionIs a Relative Notion

Scenario - Person in hurry - Has 2 minutes to catch Taxi

– If there is a long line, for example Q=10:

– Even though ATM is Operational

– For User at end of the line:

– ATM is NOT Available

Q=10Q=0

Availability

Service Level ObjectivesService Level ObjectivesService Level ObjectivesService Level Objectives

Users need to define “Availability” according to their own criteria.

Notion is called - Service Level ObjectivesIf “SLO” not met... things “slow” down.

ATM Service Level Objectives - Taxi fare:– Status = Up

– Queue = 0

– Cash = $20

Availability

Varies with UsageVaries with UsageVaries with UsageVaries with Usage

User definition of “Availability” varies with usage.

Definition of ATM “Availability” is different for $20 Taxi fare versus $300 Air fare

Goal ATM:– Status = Up

– Queue = 0

– Cash = $20

Availability

Depends on ApplicationDepends on ApplicationDepends on ApplicationDepends on Application

Availability depends on how you intend to use object.

Users define “Availability” based on their own criteria.

Goal ATM – Air Fare::– Status = Up

– Queue = 0

– Cash = $300

What if Air Fare were $800? Would ATM be available? Not dependent on Hardware.

ReviewReviewReviewReview

Availability – Has many Dependencies– Is a relative Notion– Depends on Usage or Application– Can be defined with Service Level Objectives

To provide true High Availability Enterprise– Cannot just Monitor Hardware & Operating System– But must also Monitor Availability of Application Domains– External Monitoring inadequate; Apps Hang, Loop, Deadlock– External Monitoring can’t know about internal domains & values

If Application Domain Service Levels are not monitored, it’s impossible to know when Application Domains are unavailable.

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 allows DATA to be included in an EDL File.– Allows Data to be associated with Entity-Attribute definitions.– Entities, Attributes, & Data are encapsulated all together

EDL allows encapsulation of entire ASAP environment.

EDL Provides a way to – Have different sets of customized ASAP settings.– Save your current environment for later reference.– Mail your entire ASAP environment (with data) to others.– Share observed behavior with other ASAP users.

EDL also useful for – Problem Reporting - Capture entire environment.– Prototyping – Entity, Attribute, Data definitions.– Version Independence - due to encapsulation.– Education – Demo features of environment.– QA/Testing - Reproducing test scenarios.

Availability SummaryAvailability Summary

Definition of Availability is subjective. It depends on how you intend to use object.

Studies indicate if you monitor AvailabilityActual object Availability is increased...

If Application Service Levels are not monitored, you will not know when Applications become unavailable.

ASAP provides both Availability monitoring, and Service-Level Objectives monitoring.
