Dear all,
In yesterday's Ops, I mentioned the monitoring consolidation meeting on SAM3 which took place last week. The talk on SAM3 can be found below [1]. As part of this development work, as I mentioned, a validation process is underway to understand the differences between the corresponding outputs of the SAM2 and SAM3 metrics. There's a twiki page on it [2] where you can see the currently listed discrepancies and, where applicable, an explanation.
You can see a few examples from the UK already which we had fed back; as I mentioned, it looks like most of the differences were because of additional metrics being exposed. It's worth noting that a blue result, or unknown, gives no penalty to the site as I understand it.
The examples I listed in the wiki are the only ones I could find when I went through the ATLAS UK sites last week. It would be very useful if site admins could look at the relevant experiment pages for their site from the list below and look for discrepancies between the SAM2 and SAM3 data. When I looked at the data last week I used a 48 hour period, but I think it would be more useful to expand this to a week; the links reflect this.
Please let me know if you find any discrepancies that haven't been mentioned in the twiki (I'm hoping that the sites there are covered) before Ops next week and I'll compile them to pass back to the consolidation group.

(although in this last case I note immediately that there's an issue where I couldn't see a way of selecting T2s from the list as only the T0/1s are shown)
Cheers,
David
