Drools 6包含一個跟蹤輸出，可以幫助您了解系統(tǒng)中正在發(fā)生的事情，事物執(zhí)行的頻率以及多少數(shù)據(jù)。

這也有助于理解Drools 6現(xiàn)在是基于目標(biāo)的算法，它使用鏈接機(jī)制鏈接評估規(guī)則。 有關(guān)此的更多詳細(xì)信息：

http://www.javacodegeeks.com/2013/11/rip-rete-time-to-get-phreaky.html

首先要做的是將slf4j記錄器設(shè)置為跟蹤模式：

<appender name="consoleAppender" class="ch.qos.logback.core.ConsoleAppender"><encoder><!-- %l lowers performance --><!--<pattern>%d [%t] %-5p %l%n %m%n</pattern>--><pattern>%d [%t] %-5p %m%n</pattern></encoder></appender><logger name="org.drools" level="trace"/><root level="info"><!-- TODO We probably want to set default level to warn instead --><appender-ref ref="consoleAppender" /></root> </configuration>

讓我們以購物為例，您可以在這里找到Java和Drl文件：

• https://github.com/droolsjbpm/drools/blob/master/drools-examples/src/main/resources/org/drools/examples/shopping/Shopping.drl
• https://github.com/droolsjbpm/drools/blob/master/drools-examples/src/main/java/org/drools/examples/shopping/ShoppingExample.java

運行該示例將為輸出提供非常詳細(xì)且冗長的執(zhí)行日志。 最初，您將看到插入的對象，這會導(dǎo)致鏈接。 在Drools 6算法鏈接中說明了節(jié)點和規(guī)則的鏈接。 總結(jié)1..n節(jié)點在插入對象時鏈接在一個段中。

然后1..n段鏈接到規(guī)則中。 當(dāng)一個規(guī)則被鏈接時，它就在議程上以進(jìn)行評估。

當(dāng)它最終評估規(guī)則時，它將在訪問每個節(jié)點時縮進(jìn)，從根到末端進(jìn)行評估。 每個節(jié)點將嘗試告訴您此時要插入，更新或刪除多少數(shù)據(jù)。

您可以使用此信息來查看規(guī)則評估的頻率，進(jìn)行鏈接和取消鏈接的次數(shù)，傳播的數(shù)據(jù)量以及更重要的是浪費了多少工作。 這是完整的日志：
