在ES 2.4.1中动态更新慢日志？

Question

我想为我的Elasticsearch 2.4.1启用慢日志，但当我动态尝试它时，它为我显示错误？

PUT _cluster/settings
     {
      "transient": {
        "index.search.slowlog.threshold.query.debug": "0s",
        "index.search.slowlog.threshold.fetch.debug": "0s",
        "index.indexing.slowlog.threshold.index.debug": "0s"
      }
    }

日志中的响应

此设置应在索引级给出，而不是在群集级给出。

PUT indexname/_settings
     {

        "index.search.slowlog.threshold.query.debug": "0s",
        "index.search.slowlog.threshold.fetch.debug": "0s",
        "index.indexing.slowlog.threshold.index.debug": "0s"

    }
