一、参考

elasticsearch 学习系列目录——更新ing

search log analyzer

二、Opster

2.1 装置运行

es download

kibana download

tar -xzvf elasticsearch-7.12.1-darwin-x86_64.tar.gzcd elasticsearch-7.12.1/./bin/elasticsearchtar -xzvf kibana-7.12.1-darwin-x86_64.tar.gzcd work/esEnv/kibana-7.12.1-darwin-x86_64./bin/kibana

2.2 设置慢查问

PUT kibana_sample_data_logs/_settings{  "index.search.slowlog.threshold.query.warn": "100ms",  "index.search.slowlog.threshold.query.info": "50ms",  "index.search.slowlog.threshold.query.debug": "10ms",  "index.search.slowlog.threshold.query.trace": "60ms",  "index.search.slowlog.threshold.fetch.warn": "100ms",  "index.search.slowlog.threshold.fetch.info": "50ms",  "index.search.slowlog.threshold.fetch.debug": "20ms",  "index.search.slowlog.threshold.fetch.trace": "60ms",  "index.search.slowlog.level": "debug"}

接下来，在kibana中模仿查问，产生一些慢查问日志
