As enterprises embrace the DevOps philosophy, and the coalescence of the
Development and Operations continues, I foresee the conditions ripening to
foster innovative methods of making application performance better and code
deployments smoother. To me, the argument that system monitoring is just a
“nice to have” and not really a core requirement for operational
readiness dissipates quickly when a critical application goes down with no
Application Performance Management (APM) has been bred with all the right
elements to give us the insights we need to see the health of our
applications. Similar to your most trusted watch dog, it alerts us to
anomalies when events occur, providing awareness to the environment that only
they can observe.
This is where APM can bridge the gap between Development and Operations,
supporting the entire application lifecycle. Th... (more)
Don't throw the baby out with the bathwater. Synthetic monitoring (active
monitoring) helps reduce key blind spots for critical applications. We just
experienced a production issue on a fully instrumented critical business
application that first appeared nebulous.
During peak volume time the Service Desk was taking calls from users across
random locations stating that they couldn't login, however if they were
already on the system all was well. Even when they logged out they could
still login again and continue working.
Other facts that came in made the issue more perplexing:
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)
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
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 clo... (more)
