Using JConsole in combination with SNMP
I have created a simple agent (using version 5 JDK) to handle an MBean. Within this agent I have created two adapters; an HTML and SNMP adapter. The HTML adapter is working fine via the browser (i can execute the operations on the MBean).
Question is; Can I use JConsole to connect to the SNMP adapter?; if not how then?
Code:
publicvoid addSnmpAdapter(int port)
throws Exception{
// Register and start the SNMP adapter
SnmpAdaptorServer snmpAdapter =new SnmpAdaptorServer();
ObjectName snmpAdapterName =new ObjectName(
"MBeanAgent:name=snmpadapter,type=SNMP,port=" + port);
snmpAdapter.setPort(port);
mbs.registerMBean(snmpAdapter, snmpAdapterName);
snmpAdapter.start();
System.out.println("SnmpAdapter on port " + port);
}
Start command:
java -Dcom.sun.management.jmxremote -Dcom.sun.management.snmp.acl=false -Dcom.sun.management.snmp.port=162 MBeanAgent
Hi Willem,
No you cannot use JConsole to "connect to the SNMP adapter".
JConsole is a JMX Console, not an SNMP console.
What are you trying to do with that SNMP Adaptor anyway?
If you use Java DMK to start an SNMP adapter, and do nothing more,
the adaptor will show you nothing. It is empty. You still need to
generate, implement, and add at least one SNMP MIB to the adaptor.
For more information on this, see the Java DMK documentation.

Java SE 5.0 has a built-in SNMP agent that can be started using System
properties on the Java command line. This agent implements a single MIB,
the JVM-MANAGEMENT-MIB, that exposes the JVM Management and Monitoring
data through SNMP.
See here for more info on the JVM SNMP Agent:

Hi,
It depends on what exactly you want to monitor, but it might well be that
the JVM SNMP agent and its JVM_MANAGEMENT_MIB are enough for your
needs.
The JVM_MANAGEMENT_MIB exposes almost all the information that you
can see in JConsole (except for stack traces and Sun's extension).
You will find plenty of information on that subject on my blog.
Hope this help,
