dynamically disabling prometheus exporter to reduce log messages

[ewolfman]

Hi,

I am trying to reduce the amount of Prometheus log messages while setting the Elasticsearch cluster to DEBUG.
The following does not work as I get tons of DEBUG messages.

PUT /_cluster/settings
{
  "transient": {
    "logger._root": "DEBUG", 
    "logger.org.elasticsearch.rest.prometheus.RestPrometheusMetricsAction": "INFO"
  }
}

Therefore I tried to temporarily disable prometheus as stated here: https://github.com/vvanholl/elasticsearch-prometheus-exporter#install like so:

PUT /_cluster/settings
{
  "transient": {
    "prometheus.cluster.settings": false,
    "prometheus.indices": false
  }
}

But I still see log messages like so:

{"type": "server", "timestamp": "2022-06-29T15:52:51,969Z", "level": "DEBUG", "component": "o.e.r.p.RestPrometheusMetricsAction", "cluster.name": "###", "node.name": "###", "message": "Registered new cluster gauge index_querycache_cache_count", "cluster.uuid": "####", "node.id": "###" }

How can this be achieved?
