With the complexity of today’s modern IT
environments and the multitude of delivery mechanisms available, it’s safe to
say that organizations are swamped with data.
The challenge for implementing capacity
management is being able to distil this wealth of information into a useable
form. Rather than concentrate on
specific platforms or metrics, I have found the following to be a useful guide
for filtering information:
·
If implementing for the
first time, follow the usual ITIL guidance of starting small and building
up. For capacity management this could
be starting with a particular platform, service or application.
·
Work with technical teams to
understand which metrics are available for each of the platforms. This is especially important when dealing
with virtualized platforms as these tend to have various levels e.g. cluster,
host, guest etc which are key for capacity planning.
·
Work with the application
and service support teams to determine all valid metrics and importantly how
these can be correlated with the underlying infrastructure data.
Remember, the more data captured, the more
you need to store, manage and understand.
As well as the obvious capacity implications of storing more and more
data, you are also increasing the likelihood of missing key alerts and data
trends.
On Wednesday I’ll be looking at your most
important asset, People.
