怎么保存Druid的监控记录

温高铁 edited this page Jul 26, 2013 · 8 revisions

Druid中有DruidDataSource/Spring/Web等监控记录,其中DruidDataSource提供了保存监控记录的API。

保存DruidDataSource的监控记录

DruidDataSource有一个属性timeBetweenLogStatsMillis,配置timeBetweenLogStatsMillis>0之后,DruidDataSource会定期把监控数据输出到日志中。

  <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
  	... ...
  	<property name="timeBetweenLogStatsMillis" value="300000" />
  	... ...
  </bean>

或者通过jvm启动参数来指定,例如:

  -Ddruid.timeBetweenLogStatsMillis=300000

定制StatLogger

DruidDataSource是通过com.alibaba.druid.pool.DruidDataSourceStatLoggerImpl.DruidDataSourceStatLoggerImpl来实现输入监控数据到日志的,你可以自定义一个StatLogger,例如:

Java代码

  import com.alibaba.druid.pool.DruidDataSourceStatLoggerAdapter;
  import com.alibaba.druid.pool.DruidDataSourceStatLogger ;
  public class MyStatLogger extends DruidDataSourceStatLoggerAdapter implements DruidDataSourceStatLogger {
  	... ...
  }

配置

  <bean id="myStatLogger" class="com.mycompany.MyStatLogger">
  	... ...
  </bean>
  <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close">
  	... ...
  	<property name="statLogger" ref="myStatLogger" />
  	... ...
  </bean>
