How to monitor different domains with Glassfish V2 SNMP 1.0
It is possible with Glassfish V2.1 to monitor different domains. In this blog, we will explain how to proceed.
Relationships between domain/DAS/ SNMP
The DAS (Domain administrative server) is the central piece of administration. A DAS is corresponding to a specific domain associated to a given administrative port.
DAS with server instance, cluster instances within same domain
Glassfish V2.1 allows to create server and cluster instances instances within the same domain. Glassfish SNMP V2.1 allows to monitor SNMP at:
* DAS level
* standalone instance level
* cluster instance level
It is even possible possible to deploy the snmp war file on the DAS, and on cluster instances at the same time by using different SNMP port. This is described in the SNMP documentation at:

Configuring Glassfish SNMP to monitor different domains
In this section, is shown how to monitor different domains through Glassfish SNMP. Let's assume that we create 3 different domains: domain1, domain2, domain3. Those 3 domains need to have 3 different administrative ports (4849, 4850, 4851)
asadmin create-domain --port 4849 domain1 --user admin
asadmin create-domain --port 4850 domain2 --user admin
asadmin create-domain --port 4851 domain3 --user admin
The user needs to assign a specfic SNMP port for each domain:
asadmin set --port 4849 --user admin server.property.snmp-adapter-port=10163
asadmin set --port 4849 --user admin server.property.snmp-adapter-port=10164
asadmin set --port 4849 --user admin server.property.snmp-adapter-port=10165
The user should restart each domain for each snmp-adapter port value to be taken account
asadmin stop-domain domain1
asadmin start-domain domain1
asadmin stop-domain domain2
asadmin start-domain domain2
asadmin stop-domain domain3
asadmin start-domain domain3
The user can now deploy the Glassfish snmp war file within each domain
asadmin deploy --port 4849 __assnmp.war
asadmin deploy --port 4850 __assnmp.war
asadmin deploy --port 4851 __assnmp.war
Viewing snmp data within the different domains
snmpwalk -c public -v 1 <hostname>:10163 J2EE-MIB::j2eeDomTable
J2EE-MIB::j2eeDomMoName.1 = STRING: "domain1"
J2EE-MIB::j2eeDomEnterprise.1 = OID: J2EE-MIB::sun
J2EE-MIB::j2eeDomMoStateManaged.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomMoStatProv.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomMoEventProv.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomSMState.1 = INTEGER: running(4)
J2EE-MIB::j2eeDomSMStartTime.1 = STRING: "Thu Aug 06 10:13:56 MEST 2009"
snmpwalk -c public -v 1 <hostname>:10164 J2EE-MIB::j2eeDomTable
J2EE-MIB::j2eeDomMoName.1 = STRING: "domain2"
J2EE-MIB::j2eeDomEnterprise.1 = OID: J2EE-MIB::sun
J2EE-MIB::j2eeDomMoStateManaged.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomMoStatProv.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomMoEventProv.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomSMState.1 = INTEGER: running(4)
J2EE-MIB::j2eeDomSMStartTime.1 = STRING: "Thu Aug 06 10:11:43 MEST 2009"
snmpwalk -c public -v 1 hostname:10165 J2EE-MIB::j2eeDomTable
J2EE-MIB::j2eeDomMoName.1 = STRING: "domain3"
J2EE-MIB::j2eeDomEnterprise.1 = OID: J2EE-MIB::sun
J2EE-MIB::j2eeDomMoStateManaged.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomMoStatProv.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomMoEventProv.1 = INTEGER: false(2)
J2EE-MIB::j2eeDomSMState.1 = INTEGER: running(4)
J2EE-MIB::j2eeDomSMStartTime.1 = STRING: "Thu Aug 06 10:14:37 MEST 2009"
TroubleShooting Glassfish Snmp
If you are not able to see the SNMP values, you check the glassfish server.log log file, and see within the log file to check that the SNMP value is correct for this specific domain:
* SNMP Adapter Port: <value port> ( or example 10164 in case of domain2)
