    [ https://jira.jboss.org/jira/browse/JGRP-1065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12487899#action_12487899 ] 

Bela Ban commented on JGRP-1065:
--------------------------------

The syntax is
probe.sh op=STABLE.runMessageGarbageCollection[arg,1 arg2, argN]

The angle bracket were picked because round brackets have to be escaped in most shells

> Needed for diagnosis.
> Add the ability to invoke simple operations via probe.sh (on all reachable instances). This is faster than having to start jconsole, finding the right member and invoking the op.
> Syntax: probe.sh op=STABLE.runMessageGarbageCollection arg1 arg2 ... argN
> This will find protocol STABLE and invoke operation runMessageGarbageCollection with the args given. Method matching is done on a simple argument length to parameter length comparison, and Method.invoke() is used to cast arguments (which are strings) to the parameter types.
> Possible return values are sent in the hashmap, key: "STABLE.runMessagegarbageCollection", value: return value, as string
