TDS & Capacity Planning at Emfisys

Introduction

Combined presentationTDS experienceCapacity Planning website

Currently using TDS SPP and BMC Patrol Perform & Predict Data from 100+ servers (40+

applications)Small fraction of BMO total server farm, will

expand to 1,500+Historical data kept for capacity planning,

daily reports to intranet

TDS Experience at Emfisys

Background

Using BMC Patrol since 1997 Data from 40+ servers, almost 20 services

and growingLooked at alternatives summer 2000

Tivoli onsite & strategicBMC Patrol & Datametrics Viewpoint also onsiteEvaluated TDS, Patrol, Viewpoint

Installed TDS in production January 2001

Database moved February 2002

Configuration

All data from single TMR Soon to collect from three more Many gateways

Single TDS server handles all functions TDS application, Cognos cubes, also

Oracle databases (SPP, maybe others) SPP database on TDS servers

Gives TDS users access to raw data Inventory database helps billing & costing


6


Successes

Collecting performance data from 100+ production servers Producing daily reports for 40+ business

applications on BMO intranetBenefit to application support teams

Using database with other business information to produce capacity updates

Planning to expand to 1,500+ serversMore efficient capital & expense dollars

Challenges (1 of 4)

Job timeout applies to response only All Tivoli, not just TDS

e.g. aggregation and database population jobs

Timed-out job task continues to run

Need longer baseline for extrapolating trends 6 months may exclude seasonal peaks

e.g. Christmas, RRSP seasonEnhancement requested Oct/2000, available?


8


Challenges (2 of 4)

Need workload characterizationServers will soon run multiple applications

Need differentiation between actual and forecast data

e.g. on Hourly views, can’t tell which is whichRequirement not yet raised to Tivoli

Need System Purpose matrixReplace single unsorted text-only variable in

Cube 3 with a matrix with sorting, etc.Enhancement requested Oct/2000

System Purpose Matrix Example

Server name Bus. Application Location Support Team

CVDB1 Cust. Value Toronto Team A

CVDB2 Cust. Value Montreal Team A

CVApp Cust. Value Toronto Team A

CVWeb1 Cust. Value Vancouver Team C

CVWeb2 Cust. Value Montreal Team C

CVFW1 Cust. Value Toronto Team B

CVFW2 Cust. Value Montreal Team B

Challenges (3 of 4)

Database maintenance and product recovery functions should be delivered

Oracle database cleansing, re-org, tuning, etc.Aggregation file backupDM event(s) for RIM failure, data collection

failureControl over data collection retriesPopulation job log file cleansing or rollover

New version difficultiesImplementation of DM 4.0 has yielded 42

layers instead of 18…?


11


Challenges (4 of 4)Graphics flexibility

Changes sometimes not accepted in TDSUsing Cognos as delivered with TDS helps but

design capability still limited• Exploring full-function version of Cognos, but need to

know if “new TDS” will use it

Want to include capacity threshholds on charts

Web outputJPG output files too big, GIF smallerEnhancement requested Oct/2000Automated thumbnails would be nice


12


Opportunities

Expansion planned to over 1,500 servers Capacity planning and performance

reporting handled by three-person team Enabled by top-down ability to focus on

servers trending towards trouble or running off trend

Looking to evaluate TDS Oracle, UDB, Notes and TSM Discovery Guides


13


Conclusions

TDS has potential to allow a small team to handle capacity planning for a very large number of servers

Require Tivoli support Database tuning Product enhancements

Server purpose matrixGraphics flexibilityetc.

Interlude - CP at BMOData collection

• Collect raw performance data from systems & applications, aggregate to repositories

Performance reporting• Publish to intranet daily or...

Data inspection• Learn trends and usual patterns• Problem notification to support teams as needed

Emfisys Capacity Planning Website

Background

Website in existence for many yearsMVS and other data updated daily or as neededUNIX data added starting 1997

UNIX website redesigned 1999/2000Reorganize data by type of serviceGroup charts to avoid scrolling pagesShow daily data week by week

Development continuesAdd application data, improve groupings &

accessibility

Discussion

Anyone else using TDS SPP for capacity planning or performance reporting? Successes, challenges, opportunities

Anyone using TDS Oracle, UDB, Notes or TSM Discovery Guides?

Anyone else presenting performance data for large numbers of servers?

Questions?
