使用监控工具:利用Kibana、Prometheus + Grafana等监控工具获取性能数据。 分析查询语句:检查查询语句的复杂性和效率,找出潜在的性能瓶颈。 五、提升Elasticsearch查询性能的具体建议 合理配置内存参数:如maximum_memory_per_shard、max_memory_per_query等,以确保内存分配合理。 数据分布均匀:确保数据在集群中的分布均匀,以...

It’s important to define the correct mapping to avoid problems at query time. For example, you want to avoid having Elasticsearch identify some field as Number and then later try indexing data that, in that same field now contains a string. Trying to index such data will fail. Segments A...

You can use other variables inside the query. This example is used to define a variable named$host: This uses another variable named$sourceinside the query definition. Whenever you change the value of the$sourcevariable via the dropdown, Grafana triggers an update of the$hostvariable to contai...

-d ' { "runtime": { "hour_of_day": { "type": "keyword", "script": { "source": "emit(doc[\"@timestamp\"].value.getHour().toString())" } } } }' Then I can query that here: Why do we need this feature? Because runtime fields are not exposed by default and are very ...
牛逼的集群运维需要结合可视化工具(如:kibana,cerebro,elastic-hd,Prometheus + grafana,结合业务自研工具如 阿里云Eyou等)能极大提高效率。 1、集群健康维度:分片和节点 集群、索引、分片、副本的定义不再赘述。分片数的多少对集群性能的影响至关重要。分片数量设置过多或过低都会引发一些问题。
