WATO has now a new function Rename Host. You will find a button with that name in the Properties of a host. It allows a renaming of an existing host. Before you can use that feature you need to have all changes activated, so nothing is pending.

Renaming a host is a complex precedure that will not only rename the host in WATO, but also in:

  • all rules from Host & Service Parameters
  • cluster's node definitions
  • a host's parent definitions
  • Business Intelligence rules
  • notification rules (both rule based and flexible notifications)
  • internal Check_MK data like caches and performance counters
  • auto-disovered services of the host
  • logfile information of logwatch plugin
  • stored SNMP walks
  • RR databases with performance data
  • RRD updates in journal of RRD Cache
  • spool files of PNP4Nagios
  • NagVis maps
  • monitoring history entries (events and availability)
  • the current monitoring state (including ackowledgements and downtimes)

Please note that renaming of a host involves a temporary stop of the monitoring core. This is neccessary in order to avoid situation where the old and the new name of a host is being used at the same time.
