When using the host rename feature of WATO and setting a new name that contains a dot, for example myhost.domain, the rename failed to set a correct new name. Instead of setting the intended name, the name was set to "myhost[.]domain" in different places.

The affected files are:

• Nagios core: var/nagios/retention.dat
• NagVis maps: etc/nagvis/maps/*.cfg
• Monitoring history of all supported cores:
  • var/check_mk/core/history
  • var/check_mk/core/archive/*
  • var/nagios/nagios.log
  • var/nagios/archive/*

In case you did such a rename action, you can stop your site and fix the wrong names in the mentioned files on your own, e.g. by using sed.
