Is it possible to read a child attribute via CLI ?

[markboletti]

Dear JBoss users,

I'm writing a small script which gets some KPI from the application server. I'd need to pickup some memory usage info which is contained in the heap-memory-usage attribute of the platform-mbean.

[standalone@localhost:9999 /] /core-service=platform-mbean/type=memory:read-resource(include-runtime=true)

{

    "outcome" => "success",

    "result" => {

        "heap-memory-usage" => {

            "init" => 67108864L,

            "used" => 22823600L,

            "committed" => 65208320L,

            "max" => 518979584L

        },

        "non-heap-memory-usage" => {

            "init" => 35815424L,

            "used" => 42499472L,

            "committed" => 52985856L,

            "max" => 325058560L

        },

        "object-pending-finalization-count" => 0,

        "verbose" => false

    }

}

How can I read a child attribute such as the "used" or "max", which are child of heap-memory-usage ?

Thanks

I think the closest you can get with a CLI command is

/core-service=platform-mbean/type=memory/:read-attribute(name=heap-memory-usage)

{

    "outcome" => "success",

    "result" => {

        "init" => 67108864L,

        "used" => 119206544L,

        "committed" => 272367616L,

        "max" => 477233152L

    }

}

The problem is that "heap-memory-usage" and "non-heap-memory-usage" are attributes of type ModelNode.Object.  If you want to write a script that pull out only "used" or "max" I think you wil need to use Advanced CLI scripting with Groovy, Rhino, Jython, etc.
