Puppet users - Jul 2012 - Creating Subgroups in Puppet Dashboard

Hi All,
 
Is there a feasibility for creating subgroups on the Puppet Dashboard? 
Basically the requirement is that we have a huge number of VMs running 
designated services. Some of VMs having the same service may yet have 
different properties configured on them. We are exploring the feasibility 
of having these properties managed through puppet. Currently all these VMs 
are put into a single group on the Puppet Dashboard and have global 
properties configured on the dashboard. 
 
Can I create a subgroup among these, and configure separate properties so 
that when the Agent contacts the master, based on the subgroup it belongs 
the corresponding property values are picked up (or else the default 
entries are retained)??? 
 
 
Thank you,
 
Praveen

Yes, you can. It''s quite simple:

Create a new group for your sub-group, then in the "Groups" field,
enter
the name of the parent group.

The new subgroup then inherits all of the properties and classes from
the parent group, and you can override properties by entering new values
for them in the subgroup.

You can also override individual properties by setting them on the node
directly, in case you have a one-off situation.

@Calvin:
 
Thanks for the inputs. I had infact fixed it a few days ago.  I created a 
new group and inherited the parent class into it. After that I defined a 
parameter with the same name as was in the "All Nodes" section and
over rid
the value in this new group. Now all the nodes added to the group use the 
new value and the older value defined earlier has sort of become default in 
nature, if nothing is specified.
