To display monitoring statistics for an application component or subsystem for which
monitoring has been enabled, use the
asadmin get command.

To get the statistics, type the asadmin get command in a terminal window, specifying a name
displayed by the list command in the preceding step. The following example attempts to get
all attributes from a subsystem for a specific object:

asadmin> get --user adminuser --monitor server.jvm.*

The command returns the following attributes and data:

server.jvm.dotted-name = server.jvm

server.jvm.heapsize-current = 21241856

server.jvm.heapsize-description = Provides statistical information about

the JVM’s memory heap size.

server.jvm.heapsize-highwatermark = 21241856

server.jvm.heapsize-lastsampletime = 1080232913938

server.jvm.heapsize-lowerbound = 0

server.jvm.heapsize-lowwatermark = 0

server.jvm.heapsize-name = JvmHeapSize

server.jvm.heapsize-starttime = 1080234457308

server.jvm.heapsize-unit = bytes

server.jvm.heapsize-upperbound = 518979584

server.jvm.uptime-count = 1080234457308

server.jvm.uptime-description = Provides the amount of time the JVM has

been running.

server.jvm.uptime-lastsampletime = 1080234457308

server.jvm.uptime-name = JvmUpTime

server.jvm.uptime-starttime = 1080232913928

server.jvm.uptime-unit = milliseconds

For further examples using the get command, refer to

“Examples of the list and get

Commands” on page 196

. For further information on the dotted names you can use with the get

command, refer to

“Understanding and Specifying Dotted Names” on page 195

.

Understanding and Specifying Dotted Names

In the asadmin list and get commands, specify the dotted name of monitorable objects. All
child objects are addressed using the dot (.) character as separator, thus these are referred to as
dotted names. If a child node is of singleton type, then only the monitoring object type is needed
to address the object, otherwise a name of the form type.name is needed to address the object.

For example, http-service is one of the valid monitorable object types and is a singleton. To
address a singleton child node representing the http-service of instance server, the dotted
name is:

server.http-service
