It would be realy great if the sydi-overview.vbs script
could add an additional worksheet for disk information
(size, free space, etc), and then to convert this in a bar
graph layout in order to visually represent space
availability for capacity planning purposes.
P.S. Great work

Could you please describe how you want the bar graph to look
like or perhaps send me an example excel file by email?

I agree. This would be a huge help.

Bar graph should have one column per disk, with all disks
associated to a host grouped together. Each column would
show used & free space in different colours.
E.G. (Please forgive my crude diagram)
+ +
+| + |
| | | |

Host1 Host2
I am open minded as to if the verticle scale should be in MB
or percentage used (ideally 2 graphes would be nice) but
would lean towards MB as my preference.
Nice but not essential, would be if you hover over each
column they are able to give additional info as to the disk
type (e.g. SCSI, SAN, IDE, etc)
Thanks for your fast response to my enquiry, it is greatly
appreciated.

Hello,
I've looked at the diagram on this page and the file Adam
sent me. The problem I see with this is that if done in
Excel the chart quickly becomes bloated, it works fine with
5-10 computers but if you have 20 or over it gets quite hard
to read the chart. 120 computers more or less just gives a
big blob :)
Do you have any suggestions for these scenarios?
Regards

Can I suggest several smaller graphs, each containing 10-20
servers. With each graph then scaled so that it would print on
an A4 page.
A variation to this would be a cell that allows you to configure
how many servers per graph, and another for the paper size
to scale each graph to (I need A4, but no doubt plenty would
want A3 or US Letter).
Sorry but I can't think of any other alternatives.

While the graphing would be nice, I beleive that having the
RAW data in the overview script is the part that would benifit
me the most. I could always manually create the needed
graphs. I usually am working with departmental servers so I
would probably group them that way.
Thank you very much for looking into this. I will take quite a
lessonfrom your code as I could not figgure out how to get
the information in there myself. I am still quite a novice at VB
scripting.

Adam:
If we just have the raw data in the overview part should we
just use the total space and free space or only C:?
Otherwise it will be easier to use a separate sheet.

Any raw data would need to be total space and free space on
each disk and not just c:
If we intend to use raw data then knowing the volume types
(IDE/SCSI/SAN/etc) and the model would also be usefull.
My original intention when I made the request was to be able
to trend disk usage on all disks so that I could predict growth
patterns across all volumes in order to proactively
replace/upgrade disks before they filled up. This is easier to
view graphically hence the original request.
Just a thought...but as Adam is needing to group his servers
by department then perhaps he could run the sydi-
overview.vbs script several times with the appropriate list of
department servers in each run. This way his graph would be
small enough to get the detail he wanted and also grouped
by department as he is required to report upon. This would
also leave the full reporting functionality originally requested
available to other users.

I have to agree with Anona that I would need more than just
the C: drive specs. I like the idea of knowing what type of
drive it is as well. For me this is just to ease the burden of
reporting on our server utilization. I already group the servers
by department so I don't end up with more than 10 or so in a
group.
I have found it useful to pull the entire Domain in run it on
everything, Including workstations. I that instance I would
graph it as the number of systems with over 50% free space,
40%, 30%,... That would be a manual graph but I have found
it difficult to pull the data from the XML files individually.
Especially when we are working with 300+ systems.
I guess my biggest thing is to have the flexability to
manipulate the data in Excel. I was just not able to get the
right sub routine to pull the data from the XML files.
On a side note I did add the transform functionality to the
wrapper script. This has helped me automate the gathering of
data and posting it to our infrastructure intranet site for DR
purposes.
Thank you again for writing this awsome set of scripts.
