$cluster variable for Elasticsearch 7.x

Hello,

I’m trying to setup a datasource for Elasticsearch and added to the query : {“find”:“terms”,“field”: “cluster_name.keyword”}, but it doesn’t find anymore my cluster. I have this result


{
“name” : “node735”,
“cluster_name” : “elk_clogsdev_logging”,
“cluster_uuid” : “XXVCSSB-RXialcTi6U961A”,
“version” : {
“number” : “7.2.0”,
“build_flavor” : “default”,
“build_type” : “rpm”,
“build_hash” : “508c38a”,
“build_date” : “2019-06-20T15:54:18.811730Z”,
“build_snapshot” : false,
“lucene_version” : “8.0.0”,
“minimum_wire_compatibility_version” : “6.8.0”,
“minimum_index_compatibility_version” : “6.0.0-beta1”
},
“tagline” : “You Know, for Search”
}

Is that query still correct ?

Thank you,
Adrian
