AS7 modcluster load-metric capacity value for "heap"

[bhaveshbhagat4]

Hi,

I am trying to configure load-metric type to "heap". From the following thread, it is apparent that I need to set capacity to actual value of heap (in MB).

https://community.jboss.org/message/726617

My question is, can I set this capacity value to picked-up dynamically (to match whatever I have set as "max-heap" --- something like follwoing) ?

/profile=full-ha/subsystem=modcluster/mod-cluster-config=configuration/dynamic-load-provider=configuration/load-metric=jvmHeap/:add(type=heap,capacity="${jvm.max.heap}",weight=1)

Any help would be greatly appreciated.

Thank you!

That's not correct.  The "heap" load metric already returns a ratio of used heap to max heap.

You do not need to define a capacity (i.e. capacity defaults to 1), unless you want to handicap some of your nodes for some reason.

Hi Paul,

Thank you for your response. I will try configuring it without the the capacity and see how it goes.

Thanks again!
