Subject RE: javax.management.AttributeNotFoundException
Date Thu, 26 Apr 2012 10:25:27 GMT

We are fetching the values through MBeanServerConnection::getAttribute("X") method. I went
through the Camel source code where these attributes are obtained through  org.apache.camel.management.mbean.Statistic.

I tried (non-static way) -
MBeanServerConnection::getAttribute("org.apache.camel.firstExchangeCompletedTimestamp")
MBeanServerConnection::getAttribute("firstExchangeCompletedTimestamp")

But none seems to be working.

Hi

Yeah Camel 1.x and 2.x has changed.

The API for JMX is now in javadoc, and you can see the attributes here
http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/api/management/mbean/ManagedPerformanceCounterMBean.html

from this package
http://camel.apache.org/maven/current/camel-core/apidocs/org/apache/camel/api/management/mbean/package-frame.html

Problem is with "FirstExchangeCompletionTime". So I am concluding that there might not be
any possible problem revolving the server connection. When we were at Camel.1.6.4, the same
line of code for the attribute "FirstExchangeCompletedTimestamp" used to work fine. Had there
been any change in JMX set up after Camel 1.6.4?
