How to Configure SNMP Counter Monitors

Question

Hi there,
I want to receive a SNMP trap if attributes of the SNMP Agent (JMX
MBeans) change in WLS 6.1. I'm playing around with the PetStore
example that is part of the package. I enabled SNMP and configured
localhost as a TrapHost, great ! Now I want to configure a couple of
Counter and Attribute Monitors. What do I put for
Monitored MBean Type
Monitored MBean Name
Monitored Attribute Name
if I want to monitor e.g.
ejbEntityHomeRuntimeTransactionsCommittedTotalCount Attribute in the
EJBEntityHomeRuntime Table ??
I have trouble getting it working,
thanks for any help,
Alex
Bonus question: Do I need to do this always with the Admin Console or
can I edit the config.xml file myself ?

Answer 1

well, here is the way you can set up a SNMP String Monitor for monitoring
the changes to the FileName attribute in the LogMBean:
Monitored MBean Type - Log
Monitored MBean Name - myserver
Monitored Attribute Name - FileName
The easiest way to figure these attributes is with the help of the
JavaDocs for MBeans. Please verify the data type that the method returing
attribute that you are trying to monitor with the type of the monitor you
are trying to set.
ie, you cannot setup a String monitor for a boolean attribute in the
mbean.In the case above, the getFileName method returns a String object,
so it makes sense to set a String monitor for it!
You can setup your monitor for EJBEntityHomeRuntime in a similar fashion!
Its not necessary to specify the complete ObjectName in the
MonitoredMBeanName. as the WLS constructs it automatically from the the
Name, Type and the target to which you target this trap monitor.
Hope this helps,
