What Host name based tagger is done for

You can define a tagger that will use the Host name to automatically add host templates to detected objects. The common tagger named regexp-tags can load new ip range rules with modules.

How to define a new Regexp rule

For each Regexp rule, you will need to define a new module and add it in the regexp-tags tagger configuration.

You can copy the sample module /etc/shinken/modules/sync-regexp-tag.cfg into a new file name and edit it:

define module{
  module_name       sync-regexp-tag-windows
  module_type       sync-regexp-tag
  matched_prop      host_name
  matched_regexp    .*srvwin.*
  method            append
  property          use
  value             windows
}

The properties are:

• module_name: must be unique in the modules
• module_type: must be equal to sync-regexp-tag

• matched_prop: the property that we will match. By default the property is host_name (Name of the host object)

• matched_regexp: Regexp that the object must match to activate this rule

• method: how you want to modify your detected object:
  • replace: put the value if not another one is in place
  • append: add the value at the END of the host templates
  • prepend: add the value at on the BEGINING of the host templates
  • set: just the value, erase what was before.
• property: which host property to change. By default the property is "use" (host templates)
• value: which value to set/append/prepend/replace

Then you must edit the ip-tags tagger definition to link your new module in the file /etc/shinken/taggers/regexp-tags.cfg:

define tagger {
  tagger_name    regexp-tags
  order          1
  modules        sync-regexp-tag,sync-regexp-tag-windows
  description     This tagger will tag host based on the host_name
}

Then you must restart your shinken-synchronizer daemon.
