Cronjob is done via "create-fedfiles.sh" script. From that script, we are calling "create_allow-list.sh" and "create_fedmaps.py"
create_allow-list.sh:
-Input :
Redirector names -> cms-xrd-global.cern.ch:1094 and cms-xrd-transit.cern.ch:1094
-Purpose :
Query gloabal redirectors above and get the sites and regional redirectors who are subscribed to these global redirectors.
-Output :
Allow list of both US and EU regions are produced.
Host names are produced for both production and transational federation. (prod.txt and trans.txt)
create_fedmaps.py :
-Input :
1. Hostnames in in/prod.txt and in/trans.txt
2. http://dashb-cms-vo-feed.cern.ch/dashboard/request.py/cmssitemapbdii
-Purpose :
We want to convert hostnames to "cms sitenames", e.g t2-cms-xrootd01.desy.de ---> T2_DE_DESY.
-Output :
JSON file which consists of 3 categories :
1. Production Federation
2. Transitional Federation
3. Nowhere Sites. (Sites which are not subscribed to any redirector.)
