전단 로그 모니터링 - Nodejs Elastic Search 를 통 해 데이터 프로 세 스 조회

1. es 클 라 이언 트 연결 만 들 기

var elasticsearch = require('elasticsearch');
const Service = require('egg').Service;

let esClient;
class EsBaseService extends Service {
   getEsHost() {
       let esHost = '172.21.101.22:9200';
       if (this.ctx.helper.isPro()) {
           esHost = '172.2.101.2:93200';
       }
       return esHost
   }

   getEsClient(argument) {
       if (!esClient) {
           this.ctx.logger.info('esClient init' + this.getEsHost())
           esClient = new elasticsearch.Client({
               host: this.getEsHost(),
               log: 'info'
           });
       }
       return esClient;
   }

   searchBucketsAndCountFromFsBugInfo(opts) {
       return new Promise((resolve, reject) => {
           this.searchFromFsBugInfo({
               body: opts.body
           }).then(function (body) {
               let data = {
                   name: opts.name,
                   count: body.hits.total.value,
                   buckets: body.aggregations[2].buckets
               };
               resolve(data)
           });
       });
   }
  
   searchFromFsBugInfo(opts){
       return this.getEsClient().search({
           index: 'fs-bug-info',
           body: opts.body
       });
   }

}
module.exports = EsBaseService;

2. 조회 작업 정의

       let name = '      bug ';
       let dateRange = opts.dateRange;
