我对弹性搜索很新，喜欢创建搜索字符串以获取所有主机的cpu_user：
以下是我的索引和字段的外观：
"web_app" : {
"mappings" : {
"data" : {
"dynamic_templates" : [ {
"iostat" : {
"mapping" : {
"type" : "double"
},
"match" : "iostat_*",
"match_mapping_type" : "string"
}
} ],
"_ttl" : {
"enabled" : true,
"default" : 2592000000
},
"properties" : {
"alertCount" : {
"type" : "long"
},
"appcode" : {
"type" : "string",
"index" : "not_analyzed"
},
"collisions" : {
"type" : "double"
},
"cpu_idle" : {
"type" : "double"
},
"cpu_system" : {
"type" : "double"
},
"cpu_user" : {
"type" : "double"
},
"host" : {
"type" : "string",
"index" : "not_analyzed"
},
"ierrs" : {
"type" : "double"
},
"iostat" : {
"properties" : {
"iostat_dm-0" : {
"type" : "double"
},
"iostat_vda" : {
"type" : "double"
},
"iostat_vda1" : {
"type" : "double"
},
"iostat_vda2" : {
"type" : "double"
},
"iostat_vda3" : {
"type" : "double"
},
"iostat_vdb" : {
"type" : "double"
},
"iostat_vdc" : {
"type" : "double"
},
"iostat_vdd" : {
"type" : "double"
}
}
},
任何想法如何创建一个搜索字符串来为所有主机提取cpu用户？
我希望输出在json中，例如每个主机，时间戳和cpu_user值。
这就是elasticsearch中的实际数据：
{ "_index" : "web_app",
"_type" : "data",
"_id" : "12345",
"_score" : 1.0,
"_source":{"oerrs":"0","load_avg_1min":"0.00","thresholdValue":"8931.0","cpu_idle":"100","host":"server1","server_uptime":"117","runQ_threads":"1","iostat":{"iostat_vdc":"6.60","iostat_vda3":"3.00","iostat_vdd":"1.04","iostat_vda2":"2.90","iostat_dm-0":"3.26","iostat_vda1":"3.44","iostat_vdb":"0.45","iostat_vda":"2.90"},"ierrs":"0","appcode":"cds","load_avg_10min":"0.00","page_scanrate":"NA","memory_free":"10572","cpu_user":"0","alertCount":"6","timestamp":"2015-12-01T18:32:00.0051","thresholdLimit":"5.0","memory_used":"8398","collisions":"0","load_avg_15min":"0.00","cpu_system":"0"}
},
, {
"_index" : "web_app",
"_type" : "data",
"_id" : "456",
"_score" : 1.0,
"_source":{"oerrs":"0","load_avg_1min":"0.14","thresholdValue":"19183.0","cpu_idle":"96","host":"server2","server_uptime":"80","runQ_threads":"1","iostat":{"iostat_vdc":"2.26","iostat_vda3":"8.97","iostat_vdd":"0.80","iostat_vda2":"3.60","iostat_dm-0":"3.10","iostat_vda1":"2.41","iostat_vdb":"2.74","iostat_vda":"4.10"},"ierrs":"0","appcode":"cds","load_avg_10min":"0.25","page_scanrate":"NA","memory_free":"409","cpu_user":"3","alertCount":"28","timestamp":"2015-12-01T18:32:00.0038","thresholdLimit":"10.0","memory_used":"24692","collisions":"0","load_avg_15min":"0.43","cpu_system":"1"}
},
