(require '[clojure.java.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)
-> 0Give me all the attributes:
(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}Find an invoke an operation:
(jmx/operation-names "java.lang:type=Memory")
-> (:gc)
(jmx/invoke "java.lang:type=Memory" :gc)
-> nilConneting to another process? Just run any of the above code inside a with-connection:
(jmx/with-connection {:host "localhost", :port 3000}
(jmx/mbean "java.lang:type=Memory"))
-> {:ObjectPendingFinalizationCount 0,
:HeapMemoryUsage ... etc.}Serve your own beans. Drop a Clojure ref into create-bean to expose read-only attributes for every key/value pair in the ref:
(jmx/register-mbean
(jmx/create-bean
(ref {:string-attribute "a-string"}))
"my.namespace:name=Value")}- Clone the repo
- Make sure you have maven installed
- Run the maven build:
mvn installwill produce a JAR file in the target directory, and run all tests with the most recently-released build of Clojure.
