Shady Lane Consulting helps you get the most out of your IT resources. It is important to take a
holistic view of the environment, not focus on just one or two components.
Description of Consulting Modules
- Implement a performance management methodology using MeasureWare and PerfView
- Customers often buy tools such as GlancePlus, MeasureWare
and PerfView along with their systems, and they may even start collecting
performance data. However, they seldom develop and implement a performance
management methodology which enables them to get the most value from these
products. This module helps the customer to manage their logfiles, define
applications, develop custom graphs, etc.
- Implement Application Response Monitor (ARM)
- ARM is a feature of MeasureWare which allows for the
measurement of transaction rates and response times for a user written
application. Once the application is instrumented, the data is logged and
can be graphed with PerfView.
- Implement Process Resource Management (PRM)
- PRM allocates system resources to defined applications. A
specific application may be getting too many resources, in which case PRM
will be used to limit the available resources. In other cases PRM can be
used to ensure that a particular application is getting sufficient
resources. The need for PRM typically occurs on very busy systems with multiple
applications.
- Integrate MeasureWare with OpenView Operations (OVO)
- Customers who have implemented ITO or OVO typically have a need to integrate performance alarms into their message
browser. This module helps to define MeasureWare alarms and integrates them into
OVO.
- Integrate SAP R3 performance metrics with MeasureWare
- SAP customers can look at performance metrics with CCMS,
but like GlancePlus, it is only a snapshot of performance at a certain time.
This module provides for the SAP transaction and response time metrics to be
continuously logged and then graphed with PerfView.
- Conduct Baseline Performance Analysis
- There are multiple reasons why a customer should have a
baseline of their performance. The initial reason is to gain an
understanding of the current resource utilization, any current or potential
bottlenecks, and a general idea of available capacity. There is, however, an
even more important reason to have a baseline performance analysis. Whenever
a significant change is made to an application or to the infrastructure, it
is important to be able to determine the effect that the change has made.
This can best be done by measuring the performance again and comparing it to
the previous baseline.
- Conduct System Configuration Review / Tuning
- This module is a review
of hardware and software configuration, from a performance point of view.
The analysis of disks includes lvm as well as channels and controllers. Kernel parameters will be
reviewed. Tuning and configuration recommendations will be made.
- Conduct Oracle Configuration Review / Tuning
- The best time to do a configuration review is prior to
going live with a major application, with the hope of avoiding performance
problems. Unfortunately, this module is most commonly used when a customer
already has a performance problem, and needs help. This module is a review
of hardware and software configuration, from a performance point of view.
The analysis of disks includes lvm as well as channels and controllers and
may include tablespace layout. Kernel and database parameters will be
reviewed. Tuning and configuration recommendations will be made.
- Design & Implement Service Level Agreements
- The basis for proactive Performance Management is a
Service Level Agreement (SLA). Most customers attempt to manage performance
by monitoring system resource utilization. This can be effective in many
situations, but this approach has some drawbacks. If the end users are
satisfied with response time and throughput, it doesn't necessarily matter
how busy the system is, or whether there are any bottlenecks. On the other
hand, the demands of the application may be such that even a lightly loaded
system may not be fast enough to meet the user's needs. This module helps to
establish and monitor a performance based SLA.
- Conduct Application Design Review
- Generally, when a customer develops a new application, the
last thing that is considered are the performance objectives, and how can
the application be developed to meet the performance objectives. Sometimes,
however, the customer is aware that performance is critical, and they want
someone to review the application design from a performance perspective.
This module is intended to be used during the design phase of developing a
new application.
- Load Testing
- Load testing is similar to benchmarking, but is somewhat
different because the configuration is usually pre-determined. Prior to
implementing a major application, a load test can be used to determine the
performance of the infrastructure.
- Conduct Capacity Planning Study
- Customers are frequently asking, "Is there enough
capacity to add 100 more users?", or "What will happen to response
time if another application is added?". Capacity planning can be as
simple as doing a trend analysis, or as complex as using analytical modeling
techniques to determine the answers to questions like these. It always
starts with a Baseline Performance Aanalysis, as described above.
- Monitor Application Performance
- Monitoring application performance can take many forms. For a user-written application,
ARM can be used to measure transaction response time. Sometimes information can be extracted
from log files. Other times, custom scripts need to be written to execute and monitor dummy
transactions.
- Conduct Training and Knowledge Transfer
- Customized training can be conducted for any of HP's performance management products.
