Dashboard – Overview Scorecard
In the following example of a dashboard we can immediately see that we have a green, 2 reds and some greys. Based on the green, amber and red status we can immediately see that we have an issue with a couple of these categories, memory and I/O.

Is
this enough information? Who is viewing this information and does it tell them
enough? If management were looking at this information they would be worried as
they can see red in the status. It does scare senior management when they see a
red status, mainly due to the fact that they do not have the time or
inclination to see what is behind the issue. They would immediately be on the
phone to their capacity management team asking why there are issues and it then
causes more pressure further down the tree.
It
may be that this particular issue is not an immediate problem, maybe one of the
thresholds was breached during a certain time period and needs investigation.
Dashboard – Overview Scorecard Detail
We
can drill down and find out some further information on the issue in this case.
In
the report below there is still some red showing so it is going to have to be
investigated fully and we would need to drill down even further to find out
what applications are involved here.
In
the further drill down report below we can see that we have some paging
activity on Unix that has breached the threshold.
These
red, amber and green scorecards have to be based on thresholds.
Where
the grey is shown this simply means that there is no threshold data attached to
that.
We
need to get in to the details to understand what the root cause of the issue is
and understand whether the issue is serious or not.
On Monday I'll be taking a closer look at Unix reports. In the meantime why not take a few minutes and complete our online Capacity Management Maturity Survey to find out where you fall on the Maturity Scale and receive a 20 page report for free.
