Monitoring application performance on the surface and the currents below is a
great way to build a performance baseline and provide application fluency.
Ironically, the deep dive tools sets in place today still may not provide all
the insight you need to quickly resolve anomalous behavior.
Standing back on the shore waiting for an event to go by may not be the best
approach for proactive monitoring. Synthetic monitoring (active monitoring)
is needed to help reduce the blind spots for critical business applications.
For example, 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 the users logged out they
Adopting an Application Performance Management (APM) strategy will help you
manage the quality of the Customer Experience. The challenge is that APM has
evolved into a mosaic of monitoring tools, analytic engines, and event
processors that provide many solutions to different problem sets.
When you step back and look at the big picture it all comes into focus, but
when you're trying to rationalize one technology over another, things aren't
so clear at close range. Product overlaps, ongoing costs, and ownership come
into question, and then someone will eventually ask why so many too... (more)
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)
APM is entering into a period of intense competition of technology and
strategy with a multiplicity of vendors and viewpoints. While the
nomenclature used within its space has five distinct dimensions that
elucidate its meaning, the very acronym of APM is in question: Application
Performance ... Monitoring vs. Management.
It's strange to think that we would not normally use monitoring and
management synonymously, but when used in the APM vernacular they seem to be
interchangeable. This may be a visceral response, but I see the APM idiom
converging on itself and becoming a matter... (more)
Much like electricity, APM will take the path of least resistance when
entering into an organization, attracted to the area with the strongest need;
lightning, as soon as it is triggered, needs to find ground. It may be
brought in to help resuscitate an application that has recently become
lethargic or assist the team in rehabilitating an intrinsic codebase. Once
the goal is attained however, the propensity to pigeonhole APM as a point
solution is high.
Now contrast this with DevOps, which is moving forward with a momentum
permeating IT and giving us a means to change the way we... (more)
