[edit] Description

The RegEx match uses regular expressions to match values using their identifier. The identifier consists of the five parts that are used to identify each value list: Host, plugin, plugin instance, type, and type instance. You can configure one regular expression for each part – the RegEx match matches if all regular expressions match.

[edit] Synopsis

LoadPlugin "match_regex"
<Chain "PreCache">
  <Rule "ignore_non_fqdn">
    <Match "regex">
      Host "^[^\\.]*$"
      Invert false
    </Match>
    Target "stop"
  </Rule>
</Chain>

The above example matches all values, where the host field does not contain at least one dot, and ignore them. This can be useful on server instances to filter out values from hosts that do not report their name as fully qualified domain name (FQDN).
