1. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 1 Integrated Monitoring Dashboard An Innovative Monitoring Approach Proposal by BTIS/DB&I

2. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 2 Agenda Version 1 Opportunities Areas Version 2 Challenges Approach Involvement Additional Material

3. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 3 Version 1 Dashboard version 1 developed by DB team Delivered: 1.User control (Login) 2.Collect key counters for Monitoring Such as: Availability, CPU, Memory, SGA,Tablespace, Blocking Sessions, Top SQLs, Top Waits, Hit Ratios 3. Implement in 3 systems Currently in Apex, Trims and EAS development server -> We will move the system to production servers to realize the benefits. Major benefits Expected: 1.Increase monitoring efficiency. 2.Home developed and customized for our own projects. 3.Ease of monthly reporting by including the same charts to report.

4. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 4 Opportunities Areas Version 1 is running smoothly and during the implementation, we identify below opportunities for enhancements: 1.User control a. Enlarge user group to End users and Operators. Besides the major user DBA group, we can include End users to view online monthly reports, and pass the system to Operators to monitor, (such as current practice which Operators use Patrol to monitor systems). b. The need to define separate roles, privileges and control the access to system. 2.Dashboard Services a.Increase counters to monitor. Each project has different monitoring requirements. More counters need to be provided and customization on these counters are allowed to cater to specific project requirements.

5. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 5 Opportunity Areas (..continued) 2.Dashboard Services b.Alert mechanism Automated alert based on threshold defined for each counter by support. Introduce blackout feature so as to stop alerting during maintenance time. c.Performance baseline With more data into the system, we need to put housekeeping into place, however, data defined as baseline will be retained. 3.Reports a.Intention to post our monthly report on line, so controlled user can view from our dashboard system. b.This address another opportunity to automate our monthly reports. 4.Monitoring program depot a. Need a way to track the changes and version, and also standardize our various monitoring scripts.

6. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 6 Version 2 Version 2 is proposed to address the opportunities found during version 1 development. -> It covers all the functions in version 1 -> It includes the opportunity areas identified. Note version 2 will not replace version 1 at the moment since we need time to study the design. Version 1 can continue to be enhanced and deploy into our production systems since it servers our original purpose.

7. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 7 Challenges 1.Programming skill Identified in Version 1, we need programming specialist to realize more functions (such as customized reporting,.NET and Java programming). 2.Need to change the Version 1 architecture Version 1 is based on client server model for collection of Oracle statistics, and for SQL Server databases all statistics are stored in local server. This limited the performance of dashboard and need effort if we add into a new server. We need to introduce centralized statistics repository, and introduce agent system to upload data from separate servers into the repository.

8. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 8 Challenges (…continued) 3. Effort Enhancing of current version 1 need effort which affects our current support work. Need a way to minimize our effort while still getting the product functions we want.

9. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 9 Approach The NUS IT students need to finish one project during study, and we can get the part time student team to develop the system for us. This is the best solution for our department. By controlling the activities in development version 2, we can achieve: 1.A quality product with the required functions and delivered according to schedule. (The school has also periodic reviews from their side to ensure the delivery). 2.Minimized effort from our department. Our involvement is to provide the requirements, do periodic review, and deploy the code developed offsite into our environment. (Details are in next slide) 3. Free of charge from student project. No facilities and software licenses need to provide for the development.

10. Integrated Monitoring Dashboard SEAP/BTIS/DB&I/Mar 2010 10 Involvement NUS project requires to deliver end of December. Our total involvement for a year is 8 + 12 days (office time). Regardless of the project, we still need to standardize our collection jobs. All other development activities (including customer & development team meeting) can be taken care by Zhang after office hours.
