This is one of the use cases for expressions in the configuration model.
So in the JGroups/Infinispan subsystem the relevant attributes would
need to support expressions and the domain.xml configuration would use
expressions:
<host-topology site="${host-topology.site}"
rack="${host-topology.rack}"
machine="${host-topology.machine}"/>
The host.xml server element can be used to specify the values:
<server name="server-one" ...>
<system-properties>
<property name="host-topology.site" value="s1"/>
...
</system-properties>
</server>

Dear AS7 devs,
for the JGroups/Infinispan topology stuff (AS7-3023) I need to have some
information configured per-host. In particular I was thinking of
something like the following snippet of XML:
<servers>
<server name="server-one" group="main-server-group">
<host-topology site="s1" rack="r1" machine="m1" />
</server>
<server name="server-two" group="main-server-group">
<host-topology site="s1" rack="r1" machine="m2" />
</server>
</servers>
How and where should I add this information ?
Thanks
Tristan
