版本：7.0.0

描述

采集的数据需要存储，提供给相关人员查看系统调用链路信息，因此需要配置存储项。
一般在本地尝鲜可以使用默认的h2数据库。可以很快的部署SkyWalking服务，体验相关功能。
开发环境可以使用MySQL数据库。
测试和生产环境建议使用elasticsearch。

配置

在application.yml里面，配置storage模块。
具体配置项如下：

selector：存储选择器
elasticsearch：elasticsearch6.X以下配置项
- nameSpace：命名空间，如：SkyWalking
- clusterNodes：集群节点，如：localhost:9200
- protocol：协议，如：HTTP
- trustStorePath：SSL配置路径
- trustStorePass：SSL配置，7.0.0之后可以在secretsManagementFile里面管理
- user：用户名，7.0.0之后可以在secretsManagementFile里面管理
- password：密码，7.0.0之后可以在secretsManagementFile里面管理
- secretsManagementFile：安全管理文件
- enablePackedDownsampling：如果开启，则采样索引（小时和天精度）将向下合并到分钟索引中，es7.0.0的一个增强功能，降低50%的索引数（移除了天和小时的索引需求），但是性能和之前的几乎一致。对于es6.x版本的影响只是保持小时和天的索引，用户需要手动移除他们。
- dayStep：es6.x版本，分钟/小时/月粒度的指标和追踪索引被整合到天里面，ES每天创建一个新的索引。
- indexShardsNumber：索引分片数
- indexReplicasNumber：索引备份数
- recordDataTTL：记录有效时长
- otherMetricsDataTTL：其他指标有效时长（分钟/小时/天）
- monthMetricsDataTTL：月度指标有效时长
- bulkActions：批量操作数
- flushInterval：刷盘间隔时间
- concurrentRequests：并发请求数
- resultWindowMaxSize：结果窗口最大值
- metadataQueryMaxSize：元数据查询最大值
- segmentQueryMaxSize：追踪段最大查询数
- profileTaskQueryMaxSize：性能剖析最大查询数
- advanced：
elasticsearch7：elasticsearch7.X以下配置项
- nameSpace：命名空间
- clusterNodes：集群节点
- protocol：协议
- trustStorePath：SSL文件路径
- trustStorePass：SSL PASS项，7.0.0之后可以在secretsManagementFile里面管理
- enablePackedDownsampling：如果开启，则采样索引（小时和天精度）将向下合并到分钟索引中，es7.0.0的一个增强功能，降低50%的索引数（移除了天和小时的索引需求），但是性能和之前的几乎一致。
- dayStep：
- user：用户名，7.0.0之后可以在secretsManagementFile里面管理
- password：密码，7.0.0之后可以在secretsManagementFile里面管理
- secretsManagementFile：安全管理文件
- indexShardsNumber：分片数
- indexReplicasNumber：副本数
- recordDataTTL：记录有效时长
- otherMetricsDataTTL：其他指标有效时长（分钟/小时/天）

- url：InfluxDB连接URL
- user：InfluxDB用户名
- password：InfluxDB密码
- database：InfluxDB数据库
- actions：InfluxDB收集活动数
- duration：InfluxDB等待时长
- fetchTaskLogMaxSize：请求中提取任务日志的最大数量

示例

具体配置在 application.yml 的 storage 模块。可以看出，配置项都是可以使用运行时参数替换的，也就是说，这些配置都可以在运行时指定参数。一般除了连接项，如IP，端口，用户名，密码这样的必须指定的配置项，其他配置建议使用默认值。
