The "Butterfly Effect" theoretically describes a hurricane's formation being
contingent on whether or not a distant butterfly had flapped its wings weeks
before. This highlights a sensitive dependence on environmental conditions
where a small change at one place (Dev Env) can result in large differences
to a later state (Production).
Consider the possibility that a small innocuous code change could go
undetected, promoted through Development & QA, and then have catastrophic
effects on performance once it reaches production. The environmental variants
need to be minimized and closely monitored to prevent the anomalous behavior.
Depending on transaction volume and performance characteristics there will be
a certain level of noise that will need to be squelched to a volume level
that can be analyzed. This is the precipice where APM intersects Capacity

By embracing End-User-Experience (EUE) measurements as a key vehicle for
demonstrating productivity, you build trust with your constituents in a very
tangible way. The translation of IT metrics into business meaning (value)
is what APM is all about.
The goal here is to simplify a complicated technology space by walking
through a high-level view within each core element. I'm suggesting that the
success factors in APM adoption center around the EUE and the integration
touch points with the ITIL / ITSM processes.
When looking at APM at 20,000 feet, four foundational elements come ... (more)
Convincing the astute executive who is cautious in not making an impetuous
decision on an APM investment can prove to be challenging. Consider the
amount of due diligence that is brought to bear in the decision making
process. The wide array of APM technologies that need to be reviewed can be
The selection criteria for application monitoring doesn't have to be an
arduous one, lending credence to the idea that an APM solution can be
simplified, understood, and implemented. I'm suggesting that the critical
success factors in the adoption of APM center around the End-... (more)
A look into ITIL's Continual Service Improvement (CSI) model and the
Application Performance Management (APM) framework indicates they are both
focused on improvement. I see them as being two sides of the same coin. APM
defines the approach and toolsets that CSI uses while leveraging specific
processes in Service Design, Service Transition, and Service Operation.
If you’re thinking about how to build a sustainable APM solution and how it
can be anchored into the IT culture, consider focusing on the integration
touch points with existing IT processes.
Within the CSI model there ar... (more)
Can event management help foster a curiosity for innovative possibilities to
make application performance better? Blue-sky thinkers may not want to deal
with the myriad of details on how to manage the events being generated
operationally, but could learn something from this exercise.
Consider the major system failures in your organization over the last 12 to
18 months. What if you had a system or process in place to capture those
failures and mitigate them from a proactive standpoint preventing them from
reoccurring? How much better off would you be if you could avoid the
