我需要在特定节点类型上有平均cpuload。例如，如果我将nodetype指定为tpt，则应该提供所有cpuload的{{1}} nodetype的平均值。我尝试了不同的方法但是徒劳......
我在elasticsearch中的数据如下：
tpt我的查询是
{
"took" : 5,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 4,
"max_score" : 1.0,
"hits" : [
{
"_index" : "kpi",
"_type" : "kpi",
"_id" : "\u0003",
"_score" : 1.0,
"_source" : {
"kpi" : {
"CpuAverageLoad" : 13,
"NodeId" : "kishan",
"NodeType" : "Tpt",
"State" : "online",
"Static_limit" : 0
}
}
},
{
"_index" : "kpi",
"_type" : "kpi",
"_id" : "\u0005",
"_score" : 1.0,
"_source" : {
"kpi" : {
"CpuAverageLoad" : 15,
"NodeId" : "kishan1",
"NodeType" : "tpt",
"State" : "online",
"Static_limit" : 0
}
}
},
{
"_index" : "kpi",
"_type" : "kpi",
"_id" : "\u0004",
"_score" : 1.0,
"_source" : {
"kpi" : {
"MaxLbCapacity" : "700000",
"NodeId" : "kishan2",
"NodeType" : "bang",
"OnlineCSCF" : [
"001",
"002"
],
"State" : "Online",
"TdbGroup" : 1,
"TdGroup" : 0
}
}
},
{
"_index" : "kpi",
"_type" : "kpi",
"_id" : "\u0002",
"_score" : 1.0,
"_source" : {
"kpi" : {
"MaxLbCapacity" : "700000",
"NodeId" : "kishan3",
"NodeType" : "bang",
"OnlineCSCF" : [
"001",
"002"
],
"State" : "Online",
"TdLGroup" : 1,
"TGroup" : 0
}
}
}
]
}
}
但由于无法找到确切来源而下降。
curl -XGET 'localhost:9200/_search?pretty' -H 'Content-Type: application/json' -d'
{
"query": {
"bool" : {
"must" : {
"script" : {
"script" : {
"source" : "kpi[CpuAverageLoad].value > params.param1",
"lang" : "painless",
"params" : {
"param1" : 5
}
}
}
}
}
}
}'
