篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Spark（五十）：使用JvisualVM监控Spark Executor JVM相关的知识，希望对你有一定的参考价值。

引导

Windows环境下JvisulaVM一般存在于安装了JDK的目录$JAVA_HOME/bin/JvisualVM.exe，它支持（本地和远程）jstatd和JMX两种方式连接远程JVM。

jstatd (Java Virtual Machine jstat Daemon)——监听远程服务器的CPU，内存，线程等信息

JMX（Java Management Extensions，即Java管理扩展）是一个为应用程序、设备、系统等植入管理功能的框架。JMX可以跨越一系列异构操作系统平台、系统体系结构和网络传输协议，灵活的开发无缝集成的系统、网络和服务管理应用。

备注：针对jstatd我尝试未成功，因此也不在这里误导别人。

JMX监控

正常配置：

-Dcom.sun.management.jmxremote
-Dcom.sun.management.jmxremote.ssl=false
-Dcom.sun.management.jmxremote.authenticate=false
-Djava.rmi.server.hostname=<ip>
-Dcom.sun.management.jmxremote.port=<port>

添加JMX配置：

在Spark中监控executor时，需要先配置jmx然后再启动spark应用程序，配置方式有三种：

1）在spark-defaults.conf中配置那三个参数

2）在spark-env.sh中配置：配置master,worker的JavaOptions

3）在spark-submit提交时配置

这里采用以下spark-submit提交时配置：

spark-submit --class myTest.KafkaWordCount --master yarn --deploy-mode cluster \\
--conf "spark.executor.extraJavaOptions=-Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.port=0 -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false" --verbose --executor-memory 1G --total-executor-cores 6 /hadoop/spark/app/spark/20151223/testSpark.jar *.*.*.*:* test3 wordcount 4 kafkawordcount3 checkpoint4

注意：

1）不能指定具体的 ip 和 port------因为spark中运行时，很可能一个节点上分配多个container进程，此时占用同一个端口，会导致spark应用程序通过spark-submit提交失败。

2）因为不指定具体的ip和port，所以在任务提交阶段会自动分配端口。

3）上边三种配置方式可能会导致监控级别不同（比如spark-submit只针对一个应用程序，spark-env.sh可能是全局一个节点所有executor监控【未验证】，请读者注意。）

查找JMX分配端口

通过yarn applicationattempt -list appicationId查找到applicationattemptid

[[email protected]143 bin]# yarn applicationattempt -list application_1559203334026_0015
19/06/01 17:57:18 INFO client.RMProxy: Connecting to ResourceManager at CDH-143/10.dx.dx.143:8032

通过yarn container -list aaplicationattemptId查找container id list

然后通过 pid 找到对应JMX的端口

[[email protected]146 ~]# sudo netstat -antp | grep 9000

结果中看，疑似为48169或37692，稍微尝试一下即可连上对应的 spark executor

使用JvisulaVM.exe工具添加监控

在本地windows服务器上找到JDK的目录，找到文件$JAVA_HOME/bin/JvisualVM.exe，并运行它。启动后选择“远程”右键，添加JMX监控
