How to enable JCA Resource Adapter statistics permanently in EAP 6/7?

Issue

• While running the following JBoss CLI command to get the runtime statistics for one of the JCA Resource Adapters, getting the following output as 0 for all the attributes:

[standalone@padrt02:20155 /] /deployment=test.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/global\/testConnector:read-resource(include-runtime=true)
{
    "outcome" => "success",
    "result" => {
        "ActiveCount" => "0",
        "AvailableCount" => "0",
        "AverageBlockingTime" => "0",
        "AverageCreationTime" => "0",
        "CreatedCount" => "0",
        "DestroyedCount" => "0",
        "InUseCount" => "0",
        "MaxCreationTime" => "0",
        "MaxUsedCount" => "0",
        "MaxWaitCount" => "0",
        "MaxWaitTime" => "0",
        "TimedOut" => "0",
        "TotalBlockingTime" => "0",
        "TotalCreationTime" => "0",
        "statistics-enabled" => false
    }
}

• After enabling the resource-adapters statistics as below started getting the following outputs as expected but after restarting the server this resource-adapters statistics is again disabled:

[standalone@padrt02:20155 /] /deployment=jaf-rte-connector.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/global\/OpscRteConnector:write-attribute(name=statistics-enabled, value=true)
{"outcome" => "success"}

[standalone@padrt02:20155 /] /deployment=jaf-rte-connector.rar/subsystem=resource-adapters/statistics=statistics/connection-definitions=java\:\/global\/OpscRteConnector:read-resource(include-runtime=true)
{
    "outcome" => "success",
    "result" => {
        "ActiveCount" => "5",
        "AvailableCount" => "31",
        "AverageBlockingTime" => "1",
        "AverageCreationTime" => "1",
        "CreatedCount" => "5",
        "DestroyedCount" => "0",
        "InUseCount" => "1",
        "MaxCreationTime" => "2",
        "MaxUsedCount" => "5",
        "MaxWaitCount" => "0",
        "MaxWaitTime" => "1",
        "TimedOut" => "0",
        "TotalBlockingTime" => "7",
        "TotalCreationTime" => "8",
        "statistics-enabled" => true
    }
}
