System Administrator’s Roles

The overall system performance is dependent upon the component which shows worst performance. So that system tuning based on real performance and/or resource utilization data is very import`ant to improve system performance. The performance of system is affected by various factors.

• CPU, Memory, Disk, and Network PerformanceBasic system hardware resources

• Database Engine• Application Framework• Applications• File systems• Others

Software Resources

• Hardware Partitioning, Virtualization• Load balancing - Nodes - Disks - Networks - Others• Application configuration• OS configuration

System Performance & Monitoring

George was in trouble. A seemingly simple deployment was taking all morning, and there seemed no end in sight. His manager kept coming in to check on his progress, as the customer was anxious to have the deployment done. He was supposed to be leaving for a goodbye lunch for a departing co-worker, adding to the stress. He had called in all kinds of help, including colleagues, an application architect, technical support, and even one of the system developers. He used email, instant messaging, face-to-face contacts, his phone, and even his office mate's phone to communicate with everyone. And George was no novice. He had been working as a Web-hosting administrator for three years, and he had a bachelor's degree in computer science. But it seemed that all the expertise being brought to bear was simply not enough. Why was George in trouble?

George is a system administrator, one of the people who work behind the scenes to configure, operate, maintain, and trouble-shoot the computer infrastructure that supports much of modern life. Their work is critical and expensive. The human part of total system cost-of-ownership has been growing for decades, now dominating the costs of hardware or software. 4

System administrators are responsible for well running and maintaining of system services.

• System resources utilization (CPU, Memory, Disk I/O, Network I/O)• Tracing system logs• Monitoring wasted resource (i.e. Memory leak)• Tracing unexpected process behavior • User account management• Support to develop application programs (Super-user support, test, execution)• Applying and integrating new H/W, S/W

Daily system operation inspection

• Applying system updates, applying patches• System backups

System administration as usual

Others

When the system performance is getting down and/or system failure occurs, system administrators try to solve the problem as soon as possible, and these activities consumes time and human resources.

• System Administrators• Database Administrators• Network Administrators• Hardware Vendor Engineers• Software Vendor Engineers• Application Developers

Holding an urgent meeting with people related with issue

• Arguing no responsibility on themselves. (If it is hard to find evidence, few people confess responsibility.)• Lack of system logs when the issue occurred• Lack of system performance data• Long time for taking action

Ordinary situation till any action taken

• Resources wasted• Customer complaints for delayed service

Following issues

Activities for troubleshooting system failure

When system failure occurs, you have to pay money for recovering.

• 2 weeks for system administrator : $6,000• Database/Application/Software administrator(each 1 week) : $9,000• Outsourcing support expense : 3 companies for a week : $9,000• $24,000 paid in total

One time system failure expense (A pay per a month - $9,000 for Advanced technician)

7

• Customer dissatisfaction• Customer call response cost• Adverse effect on the company reputation

If 6 unexpected system failure occurs per a year, $144,000 is paid for labor expense

• Resources wasted• Customer complaints for delayed service

Invisible cost

The wasted money when system issue occurred

By reducing system recovery time by 1/3, you can save $100,000 a year. (Customer satisfaction will be improved.)

• Collecting performance data regularly (every 5min ~ 10min)• Tracing system logs• Tracing system events• Reporting features• Collecting and analysis for system resource utilization • Monitoring critical processes

Common requirements for General tools and Expert tools

• Collecting very short interval performance data (by second unit)• Monitoring every single process without certain configuration• Tracing by user, process, group• System performance comparison, analysis and tracing for certain period (at the time of system failure.)• User defined script execution and tracing the outcomes• Tracing system configuration changes

Distinct requirements for Expert tools (Including System Failure Analysis)

System failure usually occurs under unexpected conditions. For instance, database engine process is the most critical one in database server. Generally, system administrators configure database engine processes should be monitored in advance. However, if an unexpected process, which in not defined to be monitored in advance, causes database server system failure, the monitoring configuration mentioned above is useless. In fact, it is impossible for system administrators to define all the impact factors, which may cause the problem of a server, whether database servers or application servers or others, to be monitored in advance. For this reason, general system management solution can not trace the root cause of the problem when system failure occurred.

onTune, a leading edge Expert System Performance Analysis solution does not need to set extra configuration. Once it installed, all the system environments including resources, processes, configurations, and others to be monitored automatically.

Expert System Performance Analysis solution can be a substitute for general System Management Solution, but vice versa can not be. Expert System Performance Solution should provide analysis functions at the time of system failure as well as real-time system monitoring features.

No difference between general System Management Solution and Expert System Performance Analysis solution?

10 Usability Heuristics for User Interface Design by Jakob Nielsen

The 10 most general principles for interaction design. They are called "heuristics" because they are more in the nature of rules of thumb than specific usability guidelines. onTune is the product satisfying these principles.

Visibility of system status : With simple and easy navigation, system performance data of past time and real-time is provided.

Match between system and the real world : Collecting all data for whatever operating system and showing it in simple words.

User control and freedom : Simple to exit from a window and take control.

Consistency and standards : Standardizing various performance data by operating systems, and providing the data in a single language

Error prevention : Eliminating error-prone conditions.

Recognition rather than recall : Easy to understand icons and menus for navigation.

Flexibility and efficiency of use : Direct access menus, right mouse button menus makes it easy to get information.

Aesthetic and minimalist design : Simple menu, intuitive icons, easy navigation for beginners
