開發(fā)環(huán)境，測試環(huán)境，預發(fā)環(huán)境和生產(chǎn)環(huán)境一般相互隔離的，使用開發(fā)環(huán)境或者測試環(huán)境可以使用cat來查看索引的情況

例如：

但預防環(huán)境和測試環(huán)境是不允許訪問的，那怎么辦呢？

可以使用后臺來查看上述信息，提供界面交互。

java client如何調(diào)用cat服務呢

舉例：

Settings setting=Settings.builder().put("cluster.name", "my-cluster").build();TransportClient client=new PreBuiltTransportClient(setting); client.addTransportAddress(new TransportAddress(InetAddress.getByName("127.0.0.1"), 9300));Map<String, IndexStats> stats=client.admin().indices().stats(new IndicesStatsRequest()).actionGet().getIndices();for(IndexStats stat:stats.values()) {System.out.println(JSON.toJSONString(stat.getTotal().getDocs()));}

輸出結果

{"averageSizeInBytes":457,"count":5966,"deleted":150,"fragment":true,"totalSizeInBytes":2798548} {"averageSizeInBytes":389,"count":11030,"deleted":52,"fragment":true,"totalSizeInBytes":4316958} {"averageSizeInBytes":545,"count":3516,"deleted":144,"fragment":true,"totalSizeInBytes":1996912} {"averageSizeInBytes":5154,"count":1,"deleted":0,"fragment":true,"totalSizeInBytes":5154} {"averageSizeInBytes":394,"count":12717,"deleted":47,"fragment":true,"totalSizeInBytes":5029512} {"averageSizeInBytes":437,"count":347,"deleted":0,"fragment":true,"totalSizeInBytes":151761} {"averageSizeInBytes":393,"count":14373,"deleted":147,"fragment":true,"totalSizeInBytes":5709073} {"averageSizeInBytes":3508,"count":3,"deleted":0,"fragment":true,"totalSizeInBytes":10525} {"averageSizeInBytes":487,"count":5374,"deleted":288,"fragment":true,"totalSizeInBytes":2762143} {"averageSizeInBytes":4790,"count":2,"deleted":0,"fragment":true,"totalSizeInBytes":9581} {"averageSizeInBytes":84,"count":10000,"deleted":0,"fragment":true,"totalSizeInBytes":849464} {"averageSizeInBytes":6374,"count":1,"deleted":0,"fragment":true,"totalSizeInBytes":6374} {"averageSizeInBytes":3862,"count":2,"deleted":0,"fragment":true,"totalSizeInBytes":7724}
