Alessandra, can we include feedback on GridView too?
a) Data retrieved from SAM and GridView is not always consistent. In
particular the Tier1 availability metrics. Gridview is the more usable
interface so we'd like to believe it.
b) I'd like a view of a subset of Tier2s, either by region or allowing
manual selection. SFT was good in letting you save settings so that you
didn't have to set up your query each time.
c) Tier2 names in GridView are nonsense. They have just made up their
own abbreviations to meet some arbitrary field constraint. A good
example of a user interface designed with the underlying system in mind,
not the user.
d) extracting data, not just plots.
I believe the item below is under way but it is worth supporting it so
it gets sufficient priority to actually be finished.
d) Some SAM failures are due to SAM, or rather not to the site. The
SAM-BDII problems are a good example of this. In evaluating site
metrics, failures due to SAM problems should be removed. A new status of
Unknown would help. Tests could be pass/fail/unknown, sites could be
up/down/unknown. A simple change would be daily availability=up/up+down
and not up/24. A more sophisticated use would be unknowns in a series of
up or down would not break the sequence. Ie up-up-up-unknown-up-up would
be treated as all ups, similar for downs.
Regards,
John

Hi,
has people seen this or did it get lost in the amount of broadcasts you
receive? No answer to me means we are all happy with what we got which
is fair enough.
cheers

Dear System Manager,
there will be a review of the SAM tests on Monday, May 21st 2007 in
order to prioritize correctly the SAM team work.
The following areas will be covered during the review:
- SAM framework
- SAM tests/sensors
- Displays: how SAM provides information to Gridview and other
interfaces to be displayed.
We would like to collect your suggestions on how to improve this
service.
Our goal in conducting this review is to help steer the SAM development
in the most effective direction. To this end, we request that you, if
possible, tell us not so much "what is wrong with SAM" but "how can we
improve SAM". It would also help if you know of small things that could
be done that would make your sysadmin life much easier; suggestions for
a complete redesign of the system are less useful (given the advanced
state of development of SAM), unless they are absolutely brilliant :)
Please send your feedback to:
Daniele Cesini <[log in to unmask]>
Alessandra Forti <[log in to unmask]>
Jeff Templon <[log in to unmask]>
by Wednesday May 16th 2007. We will summarise it and discuss it during
the review.
SAM tests documentation can be found here:
https://twiki.cern.ch/twiki/bin/view/LCG/SAMOverview
in case you want to look at it.
Thank you in advance for your cooperation
SA1 site representatives
Alessandra, Daniele, Jeff
