RE: [External] Re: org.apache.logging.log4j.jmx.HierarchyDynamicMBean not found in log4j 2
Thank you Ralph and Gary for your prompt response.
Perhaps I was not clear, the HierarchyDynamicMBean exists in the log4j-1.214.jar and our app uses it and there are no errors.
As we are trying to migrate to log4j-core-2.17.1, we noticed that HierarchyDynamicMBean is not part of log4j-core-2.17.1.jar and it is throwing errors.
My question are,
is HierarchyDynamicMBean included in log4j 2?
Is there an alternative solution/class?
Can the HierarchyDynamicMBean class be packaged part of log4j2?
Can the HierarchyDynamicMBean be extracted from log4j-1 and add it log4j-2?
Any suggestions on how to migrate log4j2?
Thank you
Shaib

I’m confused. Log4j 1.x used the package org.apache.log4j. Log4j 2.x uses org.apache.logging.log4j. So how was that class part of Log4j 1.x?
Indeed - https://secure-web.cisco.com/1aJ9StItuostdVVrk_AythzsM_-usieWrcWBvKR5Qo3pDj-R-rqduf1Y2dmHEnQf7kTAgDnS7ieZqSYFjy1d9JuT-msPOSykVoeBj4ENeM7b1Np8LTq4WujNs7qJ4Py-OZipVC4xVhgEOq1F1Yx4F_XNOHbBqw8fMHk4L6qidmMp2XYmiM6H9QAkHWYxOO8qcFhVD1zfR7iNjIkY9ypNtfAMEmXmZAj-Xo4nE3Kr-zmXVaVyV_kcUU4Xrbe2eU3rr12RxqNu7sSsy9321TvgucXV4sevmlK6Tr_W4Ur4G8BDQWhQyUbNElOJ63Pw449k83uc65i9ZzA4-X6ZRDpk2dRTLFlha1aoPXA-g3Js5eXWfCLfQglFITMzJVQWwvdusIvq5A6VK4BYVlc2zsbr5fuB7o23Gli4izJk9dlmS1FtfeN7OIYtkx8-osLuNwrT92Fy9IZI84qSAoIuKDvYIfg/https%3A%2F%2Flogging.apache.org%2Flog4j%2F1.2%2Fapidocs%2Forg%2Fapache%2Flog4j%2Fjmx%2FHierarchyDynamicMBean.html
indicates the package name you show below is wrong.
Although Gary just added the JMX components to log4j-1.2-api I don’t believe you should actually use them.
Log4j 2 comes with its own JMX support and since the design of Log4j 2 is different than Log4j 1 I suspect not everything in 1.x will work as expected.

Re: [External] org.apache.logging.log4j.jmx.HierarchyDynamicMBean not found in log4j 2
Posted by Ralph Goers <ra...@dslextreme.com>.
The reason Log4j 2 does not contain that Mean is because Log4j 2 has no Hierarchy object. Instead, it has a LoggerContext. It does have a LoggerContextAdminMBean and it has a LoggerConfigAdminMBean. The latter lets you inspect and manipulate logger configurations.
There would be no way to create the HierarchyDynamicMBean as it is defined in Log4j 1.2 as it references things that don’t exist in Log4j 2.
As for suggestions - Migrating code is largely a matter of changing the dependency and the imports and creating a suitable Log4j 2 configuration. The Log4j 2 API supports most of the Log4j 1 “api” (I use that term loosely since there was no well defined API).
The hard part comes with whatever customizations you have made or code that is accessing the internals of Log4j 1.x. Without knowing what you have done in that regard it is difficult to say what you need to do to migrate.
