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.pl
Usage: 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 line
Notes
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).
CDBAutoNotifyContacts
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
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/griddeployment/cgi-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
–…

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
