rgmanager is entirely configuration-driven; it does not monitor most things.

ricci is an optional service which is not required to run rgmanager nor the rest of the cluster software.

It's possible to make rgmanager monitor system-local services.  For example, if you had a 3-node cluster and you wanted to start and monitor specific services on each of them (ex: ricci on all 3 nodes, httpd on node 2, ricci & nfsd on node3), you could do the following:

  <failoverdomains>
    <failoverdomain name="node1" restricted="1">
      <failoverdomain name="node1" restricted="1"/>
    </failoverdomain>
    <failoverdomain name="node2" restricted="1">
      <failoverdomain name="node2" restricted="1"/>
    </failoverdomain>
    <failoverdomain name="node3" restricted="1">
      <failoverdomain name="node3" restricted="1"/>
    </failoverdomain>
  </failoverdomains>
  <rm>
    <resources>
      <script name="ricci" file="/etc/init.d/ricci" />
      <script name="httpd" file="/etc/init.d/httpd" />
      <script name="nfs" file="/etc/init.d/nfs" />
    </resources>
    <service name="monitor-node1" domain="node1">
      <script ref="ricci" />
    </service>
    <service name="monitor-node2" domain="node2">
      <script ref="ricci" />
      <script ref="httpd" />
    </service>
    <service name="monitor-node3" domain="node3">
      <script ref="ricci" />
      <script ref="nfs" />
    </service>
  </rm>

Note that services which you expect rgmanager to start and monitor, you should chkconfig off.
