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>
