NAME

    jmxstat - Poll JMX attributes and more

SYNOPSIS

    jmxstat  [--peformGC|--contention|--disable-contention] [mbean.name[attribute.field], ...] [interval [count]] 

    or 

    java -jar jmxstat-VERSION.jar  [--peformGC|--contention|--disable-contention] [mbean.name[attribute.field], ...] [interval [count]]

DESCRIPTION

    jmxstat connects to a remote JMX server via RMI and reads MBean attributes

    at a regular interval. Authentication is not supported.

    

    jmxstat supports these arguments:

    

    host:port            Host and port of the JMX enabled process to connect to

    

    mbean-attributes     Space separated list of mbean names and attributes to

                         query in the following format:

    

                            mbeanDomain:mbeanKey=mbeanValues,...[mbeanAttribute1[.field],...]

                         

                         If the attribute starts with '!' invoke the method.

    --contention         Render blockedCount and blockedTime for all threads.

                         blockedCount is the total number of times threads

			 blocked to enter or reenter a monitor.

			 blockedTime is the time elapsed in milliseconds for

			 all threads blocked to enter or reenter a monitor.

    --disable-contention Disable the blocked time monitoring activated by the 

                         --contention options.

    --performGC          Perform a full GC.

    interval             Pause _interval_ seconds between each query.

    count                Select count records at interval second intervals.

EXAMPLES

    **Precondition**. These examples assume a JMX enabled process is listening

    on localhost:9999. To use jmxstat itself as the monitored process:

    

        java -Dcom.sun.management.jmxremote.port=9999 -Dcom.sun.management.jmxremote.authentice=false -Dcom.sun.management.jmxremote.ssl=false -jar jmxstat.jar localhost:9999

    Display the number of loaded classes (every 5 seconds, by default):

    

        jmxstat localhost:9999 java.lang:type=ClassLoading[LoadedClassCount]

    

    Display heap usage and thread count every 2 seconds 3 times:

    

        jmxstat localhost:9999 java.lang:type=Memory[HeapMemoryUsage.max,HeapMemoryUsage.committed,HeapMemoryUsage.used] java.lang:type=Threading[ThreadCount] 2 3

    Display thread count and contention information:

       	jmxstat localhost:9999 --contention java.lang:type=Threading[ThreadCount] 2 3

 

    Perform a Full garbage collector:

        jmxstat localhost:9999 --performGC

    Same but using a method invocation:

        jmxstat localhost:1089  java.lang:type=Memory[!gc] 1 1

    Invoking method with parameters:

        jmxstat localhost:1089  localhost:1089  org.nuxeo:name=EventMonitoring,type=service[!setListenerEnabledFlag/auditLoggerListener/false] 1 1
