Resolution:
If we want to configure two hawk microagents for the FT EMS server (one microagent for each process), we have to configure two .hma file under the plugin folder where each file is configured to point to an EMS node (i.e. tibjmsadmin1.hma -> node1, tibjmsadmin2.hma -> node2).

For tibjmsadmin1.hma
             &ltarg>-server</arg>
             &ltarg> tcp://node1:7222</arg>
       For tibjmsadmin2.hma
             &ltarg>-server</arg>
             &ltarg> tcp://node2:7233</arg>

But we just need to perform this configuration on one computer from which we want to monitor the EMS server. This computer can be node1 or node2 or any computer in the same subnet.
