HWDB -> Snow: Status  Automatic push via the Snow JSON interface using user certificate  Synchronise the warranty information  Synchronise the host information  Incremental synchronisation  Feed Snow production  Retire machines for retired contracts Done Full data pull on regular basis

HWDB -> Snow: Future plan  TO BE FINISHED:  Pull the retired flag per host  Decided that it is not possible. Check in LANDB instead? When should the check be run?  From the HWDB or from INFOREAM  Run the code with a service account certificate  Work in progress To be finished

Puppet/Forman -> Snow: Status  Automatic push via the Snow JSON interface using user certificate  Synchronise the cluster information  Synchronise the essential flag  Incremental synchronisation  Feed Snow production Full data pull on regular basis Done

Puppet/Forman -> Snow: Status II  Snow pulls from Puppet on demand (per host)  Create a proxy code running at CERN that  Provide SOAP interface for Snow via basic authentication  Pull data from Puppet using certificate  Enhance Snow to calls the SOAP interface, whenever an alarm for unknown machine arrives  Synchronise on demand with LANDB and HWDB for the future? (for the future) Pull on demand Done To be tested

Others…  IT Contact – change the “Add CI Contacts to Watch List” action in order to merge the CDB IT Contact with the LANDB main/responsible user/e-group  Operating system is retrieved from LANDB for all network devices (going in production on Monday) Done

Pending questions  Retired information:  From where?  HWDB warranty information  How?  Marked with by retired flag - wait  Still synchronised with CDB:  Contract type, Model number – to be stopped  Department/Group ? – future: puppet master – not needed, retrieved from the FE

What else  Puppet will provide Default FE per host or host_group  Will be sent to Snow in the alarm (for special alarms).  Will be exported to Snow. In case of a new alarm coming without an FE, the incident will be assigned to the Default FE.  Could be done in LANDB maybe?  Accounts to be defined in Snow as CIs  Enclosure information  From INFOR

THANKS TO  Gavin, Miguel and Michal for the new fresh ideas and collaboration.  Alexandre who helped with the certificate usage and who provided us with final version of the two puppet views containing the essential flag and the host_group.  Steve who tries to make the Snow people life easier with special views and basic authentication access  Daniel who did the job on the Snow side  Afroditi who gave us all hwdb world
