...wants your help to be born! :-)
There is a branch in clojure-contrib that includes work so far:
http://github.com/richhickey/clojure-contrib/tree/jmx
. I want feedback on ease of use, most important features to add next,
code quality, you name it.
Here's a teaser:
-------------------------------------
Usage
(require '[clojure.contrib.jmx :as jmx])
-------------------------------------
What beans do I have?
(jmx/mbean-names "*:*")
-> #<HashSet [java.lang:type=MemoryPool,name=CMS Old Gen,
java.lang:type=Memory, ...]
-------------------------------------
What attributes does a bean have?
(jmx/attribute-names "java.lang:type=Memory")
-> (:Verbose :ObjectPendingFinalizationCount
:HeapMemoryUsage :NonHeapMemoryUsage)
-------------------------------------
What is the value of an attribute?
(jmx/read "java.lang:type=Memory" :ObjectPendingFinalizationCount)
-> 0
-------------------------------------
Can't I just have *all* the attributes in a Clojure map?
(jmx/mbean "java.lang:type=Memory")
-> {:NonHeapMemoryUsage
{:used 16674024, :max 138412032, :init 24317952, :committed
24317952},
:HeapMemoryUsage
{:used 18619064, :max 85393408, :init 0, :committed 83230720},
:ObjectPendingFinalizationCount 0,
:Verbose false}
-------------------------------------
Can I find and invoke an operation?
(jmx/operation-names "java.lang:type=Memory")
-> (:gc)
(jmx/invoke "java.lang:type=Memory" :gc)
-> nil
-------------------------------------
What about some other process? Just run *any* of the above code
inside the with-connection form:
(jmx/with-connection {:host "localhost", :port 3000}
(jmx/mbean "java.lang:type=Memory"))
-> {:ObjectPendingFinalizationCount 0,
:HeapMemoryUsage ... etc.}
