VI/VDI Performance is Tied to a Dynamic Shared Infrastructure


Insights have to be from more than just a vCenter vantage point


Comprehensive data center visibility is essential

Dynamic Interaction Tracking is a “Must Have”


Interactions must be tracked otherwise there is no context for
what’s driving resources


Live and historically


Quick surges have to be visible to be understood


Interactions come and go in a blink of an eye


Reports will average out spikes


Storage latencies are missed in the majority of environments


Negative interactions have to be played back in a way the
other “silo” can see them


Static relationships/dependencies are a notion of the past


So are products based upon that model

“Smoking Gun” Myths & Red

light Monitoring

MYTH #1

There is
A

smoking gun

REALITY

There are multiple shooters

WHAT’S MISSING

Ability to look into the other

silo with their vantage point

MYTH #2

Alerts point me

to the smoking gun

REALITY

Alerts warn me my

performance is “shot”

WHAT’S MISSING

Interactional context:

The equivalent of a “motive”
