Tiers configuration

One of the purposes of creating customized grouping pattern configuration is to define the tiers which are assigned to the elements of created groups. The elements of each group that is created by BizAppsAgent can then be divided into tiers.

The configuration for a tier contains a tier name and a set of rules with conditions. The tiers definitions are processed in the defined order. The first tier for which at least one rule meets all conditions that are defined for a particular configuration item is assigned to an element.

1Note: You can control how many tiers are processed by using the firstTierOnly parameter, which is specified in the general section of the pattern configuration. For details, see General configuration.
The customized configuration that is specific to a particular grouping pattern is processed before the default configuration.
The following example shows the simple tier configuration with the tiers definition for elements in created groups. This is also the default tier configuration.
  <tiers>
    <tier>
      <name>Computer Systems</name>
      <rule>
        <className>ComputerSystem</className>
      </rule>
    </tier>
    <tier>
      <name>App Servers</name>
      <rule>
        <className>AppServer</className>
      </rule>
    </tier>
  </tiers>
The following example shows the advanced tier configuration with the tiers definition for elements in created groups.
  <tiers>
    <tier>
      <name>My tier name</name>
      <rule>
        <className>ComputerSystem</className>
        <displayName type="wildcard">*.pl</displayName>
      </rule>
      <rule>
        <className type="strict">LinuxUnitaryComputerSystem</className>
        <displayName type="wildcard">*ibm*</displayName>
      </rule>
    </tier>
    <tier>
      <name>Windows Computer Systems</name>
      <rule>
        <className>WindowsComputerSystem</className>
      </rule>
      <rule>
        <className type="regexp">.*ComputerSystem</className>
        <expression>
          <pattern>$CI.OSRunning.OSName</pattern>
          <match type="regexp">.*Windows.*</match>
        </expression>
      </rule>
      <rule>
        <hierarchyType type="strict">WindowsComputerSystem</hierarchyType>
      </rule>
    </tier>
