Not sure if this is an ECE or just general Elasticsearch query, but I'm trying to set up watchers on node stats e.g. check JVM heap not using over 80%.

Is there a way to do this using the search input. I know it would be possible with a Http input but then I have to worry about authenticating to the cluster which isn't ideal.

\*additional query  
If I use the http request, like below, the payload has a node ID in it (see below)

```auto
"payload": {
  "nodes": {
    "s59clI5ORciYdbW16QOPfg": {
       "timestamp": 1548936254192,
        ....

```

Is there a way of

- creating a watcher that would loop through all of the nodes and alert on values in the node if a condition met
- If not "moving into" the node without having to specify the key in the watcher

Thanks
