We've setup an environment to test out this exporter. One of the metrics we'd like to monitor doesn't seem to be present: elasticsearch_indices_active_queries Here is the config we're using: /exporter-bin/elasticsearch_exporter/elasticsearch_exporter \ --es.uri="${DOMAIN_ENDPOINT}" \ --aws.region="us-east-1" \ --log.level="${LOG_LEVEL}" \ --es.all \ --es.cluster_settings \ --es.indices \ --es.indices_mappings \ --es.indices_settings \ --es.shards \ --es.snapshots \ --es.timeout="45s" \ --log.output="stdout" & I also cannot find this metric referenced anywhere in code. Has this metric been deprecated?
