How to query current cluster shard allocation setting

[LeeSyd (Lee)]

I may be doing something stupid. I'm sure I've queried under older versions but can't seem to query through the API or console to determine current cluster shard allocation setting - is anybody able to assist please?

I can enable and disable with a PUT but if I try the console with the following: -
GET _cluster/settings
{
"persistent": {
"cluster.routing.allocation.enable"
}
}

I get error: -
{
"error": "Incorrect HTTP method for uri [/_cluster/settings?pretty] and method [POST], allowed: [PUT, GET]",
"status": 405
}

You can't run:

GET _cluster/settings
{
 "persistent": {
  "cluster.routing.allocation.enable"
 }
}

You can run:

GET _cluster/settings

What is happening behind the scene of the Dev Console is that anytime you are providing a body with the GET http verb, the verb is transformed to POST.
Because browsers don't really support GET with body.
