ES（elasticsearch）,以下簡稱ES
ES的查詢有query、URL兩種方式，而URL是比較簡潔的一種，本文主要以實例探討和總結URL的查詢方式
1、語法
curl [ -s][ -g][ -X<REST Verb>][ -H 'Content-Type: application/json'] '<Node>:<Port>/<Index>[/Type][/ID]/_search?pretty&q=<search string>' 注意要用''包起來，否則后面的&會被識別為“后台執行”，即&后面的內容被忽略
-s 不輸出查詢的時間那些東西
-g 做轉義用
<REST Verb>：REST風格的語法謂詞，GET/POST/PUT <Node>:節點ip，默認使用localhost <port>:節點端口號，默認80，ES默認使用9200 <Index>:索引名，支持通配符，power_json* <Type>:索引類型，由於一個index只有一個type，可不輸入 <ID>:操作對象的ID號，可不輸入
q ：前面加&，后跟查詢語句
2、常用參數
q---查詢字符串 sort---排序執行。可以是fieldName或 fieldName:asc/ 的形式fieldName:desc。fieldName可以是文檔中的實際字段，也可以是特殊_score名稱，表示基於分數的排序。可以有幾個sort參數（順序很重要）。 from---從命中的索引開始返回。默認為0。 size---要返回的點擊次數。默認為10。 _source_include---查詢包含某些source字段的文檔。 _source_exclude---查詢不包含某些source字段的文檔。 timeout---搜索超時，將搜索請求限制在指定的時間值內執行，並使用在到期時累積的點擊數進行保釋。默認為無超時。 default_field---默認為index.query.default_field，即未指定字段前綴時返回所有字段，索引設置為* default_operator---默認查詢運算符，未指定時默認為OR。 analyzer---用於分析查詢字符串的分析器名稱。 _source---設置為false禁用_source字段檢索。 analyze_wildcard---是否應分析通配符和前綴查詢,默認為false status:active---where the status field contains active
---（status相當於fieldname,active相當於值----->TESTID：39232032303039,由於=被用在了前面“q=”,所以這里用“：”代替了“=”） title:(quick OR brown)---where the title field contains quick or brown. If you omit the OR operator the default operator will be used author:"John Smith"---where the author field contains the exact phrase "john smith" _exists_:title---where the field title has any non-null value date:[2012-01-01 TO 2012-12-31]---All days in 2012 count:[10 TO *]---Numbers from 10 upwards count:>=10---Numbers from 10 upwards
3、總覽

4、詳解
4.1、查詢節點
heap.percent：堆內存，1/2最大內存-1和31之間取較小的值，高的話就是ES集群負擔比較重，解決：關閉一些索引（閾值差不多可以定在80左右）后會釋放一部分heap.percent，但不會釋放disk.percent
ram.percent：一直挺高，物理內存的使用情況，Lucene會將閑置的內存都占用做cache，如果有應用使用內存時，cache會被釋放出來
cpu：一般不會很高，5以下吧，如果有很多query的話會高，如果一直高釋放不掉可能查詢語句有問題
node.role：【mdi】master data i查詢接口（可否在節點上查詢）
[zhang@node2 ~]$ curl localhost:19200/_cat/nodes?v ip heap.percent ram.percent cpu load_1m load_5m load_15m node.role master name 192.168.243.74 50 98 0 0.09 0.08 0.10 di - node5 192.168.243.35 39 90 0 0.11 0.19 0.23 mdi - node2 192.168.243.11 57 99 1 0.19 0.14 0.14 mdi * node1 192.168.243.51 65 95 0 0.07 0.09 0.13 di - node4 192.168.243.40 50 95 0 0.05 0.14 0.20 mdi - node3
4.2、查詢節點健康狀態
[zhang@node2 ~]$ curl localhost:19200/_cat/health?v epoch timestamp cluster status node.total node.data shards pri relo init unassign pending_tasks max_task_wait_time active_shards_percent 1561104338 16:05:38 zhang green 5 5 3074 157326 0 0 0 0 - 100.0%
4.3、查詢節點
disk.percent顯示占用的硬盤空間
[zhang@node2 ~]$ curl 'localhost:19200/_cat/allocation?v&s=node' shards disk.indices disk.used disk.avail disk.total disk.percent host ip node 615 1.9tb 9.2tb 8.9tb 18.2tb 51 192.168.243.11 192.168.243.11 node1 615 2.3tb 8.7tb 9.4tb 18.2tb 47 192.168.243.35 192.168.243.35 node2 614 2.2tb 7.6tb 10.5tb 18.2tb 42 192.168.243.40 192.168.243.40 node3 615 2.2tb 7.5tb 10.6tb 18.2tb 41 192.168.243.51 192.168.243.51 node4 615 2.1tb 7.1tb 11tb 18.2tb 39 192.168.243.74 192.168.243.74 node5
