Site naming convention

We use the BDII names. The site names displayed in the Siteview GridMap interface are downloaded from the gridops web site.

For ALICE

For every site name Costin provides 2 addition parameters: MLname and IPAddress (of the vobox I guess...).

Costin explained that there are 38 sites for which he could match the names with the names used in SAM, for the rest the name is the one from ML. For CERN ALICE have several ML instances (each on one VoBox).

Among the different names which refer to CERN, the only ones that could be summed up are CERN-L and CERN-gLite=CERN-PROD. He has removed CERN and CERN_lxgate since they represent the central services and don't run any jobs. CERN_HLT is a cluster down in Point 2, it's a totally different resource from the two above, so it should be treated separately, just as the CERNMAC cluster.

Currently (5 Nov) Costin has implemented a matching mechanism and CERN-gLite has become CERN-PROD (since there was an IP-based match between the two names; in fact we can still see the ML name in one line from the dump: CERN-PROD,general,MLname,!CERN_gLite; CERN-PROD,general,IPaddr,128.142.173.147) while for the other one (CERN-L) there was no match so it kept the ML name (CERN-L,general,MLname,CERN-L; CERN-L,general,IPaddr,128.142.173.212). Thus I can add CERN-L to CERN-PROD.

In order to make things simpler, it would be better to have one measurement per tuple (VO, activity, metric). Costin was asked then to provide only one value for CERN, instead of 2. But the answer is that he prefers to keep them separated on their side, since you can have different status codes on the two and you need the different names to correlate with the status dump page to get detailed information.

But from the site administrator point of view, does it make sense to have 2 sites called CERN for this VO? Probably no, and in any case is not something that can be fixed on Siteview side.

For ATLAS

Atlas already uses the names following the BDII convention. No need to translate.OK

For CMS

A mapping was provided by Julia.OK

For LHCb

Adrian so far has provided metrics only for the Tiers1. They are few, so I introduced the mapping by hand in my database schema. Later, more sites where added. A text file has been provided which maps the LHCb names with official names. This is a static information in the DB, this is not a good solution, because it has to be updated (if necessary) by hand
