First Use Case: “View Clusters”
• Exercise for Vasco
• Replace manually-maintained Web pages– (such as lxdev nodes usage, list of FS
clusters, …)
• CDB cluster info up-to-date – Possible applications:
• tool for generating e-mails (see further)
• …
“View Cluster” Web page
• See demonstration by Vasco: • https://oraweb.cern.ch/pls/cdbsql/web.main
“Other searches””View Clusters”
• Used fields:– /system/cluster/name
– /system/cluster/subname
– /system/cluster/description
– /system/cluster/itsection
– /system/cluster/itcontact
– /system/cluster/usercontact
– /system/quattor_managed
– /system/function
CDBAutoNotifyContacts.plUsage: try CDBAutoNotifyContacts.pl -h
Required arguments:
● --cluster_name cluster (eg. lxgate)● --os osversion (eg. Slc3)● --subject 'subject text'● --message 'path_to_body_text_as_file'
Variables:
The message text and subject may contain the variables
###NODES### will be replaced by the list of nodes
###SIGNATURE### signature for the body text, can be set on the
command lineNotes
By default, the script will only print out stuff and send nothing. Sending
is activated only by explicitly setting the debug level on the command
line to a value of 0 (zero).
History and idea
● LXGATE cluster reboot: 24 machines, different (groups of) contacts persons to be notified of reboot
● Idea: CDB contains IT and user contacts● Wrote a script to use this information, regroup
the contacts and send exactly one notification mail per user contact group, containing a list of their machines
CDBAutoNotifyContacts
Status
● In CVS, first version released on AFS today● Relies on correct user contact information in CDB!
Related Issues/Tools
• LANDB-CDB synchronisation (for “responsible” fields for “lxnoq” hosts)– Work in progress with NetOps colleagues
• Yet another DB for LCG users:– http://grid-deployment.web.cern.ch/grid-deployment/c
gi-bin/nodes-status.cgi– They should be able to use/update info from/in CDB
• “CDBUpdate” tools: – Modify user & IT contacts, … for a list of hosts– …

• From PAN to CDBW: body to be rewritten

Next Developments (3)
• GUI for cluster creation– “lxnoq” subclusters
– Normal clusters
• In both cases, perl script prototypes have been implemented (and used). Create user-defined templates from a questionnaire:
• pro_software_<cluster>
• pro_system_<cluster>
• pro_type_<cluster>_<os>
Further plans
• See requirement document
• Priorities adjusted with time and demand
