java应用程序查看之jps命令

旧城等待， 2022-02-25 15:26 260阅读 0赞

jps只显示java应用程序，与ps -ef | grep java作用类似。  
一、先man jps查看命令描述选项

$ man jps

OPTIONS  
The jps command supports a number of options that modify the output of the command. These options are subject to change or removal in the  
future.

-q
              Suppresses the output of the class name, JAR file name, and arguments passed to the main method, producing only a list of local JVM
              identifiers.
    
       -m
              Displays the arguments passed to the main method. The output may be null for embedded JVMs.
    
       -l
              Displays the full package name for the application’s main class or the full path name to the application’s JAR file.
    
       -v
              Displays the arguments passed to the JVM.
    
       -V
              Suppresses the output of the class name, JAR file name, and arguments passed to the main method, producing only a list of local JVM
              identifiers.

二、用法举例  
1、列出进程号、应用程序包名或类名

$ jps
    10097 Jps
    6755 KnDeviceTagConsumer
    24261 LoadCreditRating
    23943 fd-recommend-dubbo-provider.jar
    14808 fd-recommend-dubbo-consumer.jar
    28697 Bootstrap
    9449 KnApplistTagConsumer
    7818 dubbo-admin-0.0.1-SNAPSHOT.jar

2、列出进程号、详细包名或路径

$ jps -l
    10114 sun.tools.jps.Jps
    6755 com.feidee.bigdata.recommend.tag.device.KnDeviceTagConsumer
    24261 com.feidee.bigdata.listserv.creditrating.LoadCreditRating
    23943 /usr/local/tomcat/fd-recommend-dubbo/fd-recommend-dubbo-provider/lib/fd-recommend-dubbo-provider.jar
    14808 /usr/local/tomcat/fd-recommend-dubbo/fd-recommend-dubbo-consumer/lib/fd-recommend-dubbo-consumer.jar
    28697 org.apache.catalina.startup.Bootstrap
    9449 com.feidee.bigdata.recommend.tag.device.KnApplistTagConsumer
    7818 ./dubbo-admin-0.0.1-SNAPSHOT.jar
    32748 org.apache.catalina.startup.Bootstrap
    6878 com.feidee.bigdata.recommend.iteminfo.KnItemInfoConsumer

3、只列出进程号

$ jps -q
    6755
    24261
    23943
    14808
    28697
    9449
    7818
    10154
    32748
    6878

4、列出jvm详细参数

$ jps -v
    6755 KnDeviceTagConsumer
    24261 LoadCreditRating
    23943 fd-recommend-dubbo-provider.jar -Xms1g -Xmx1g
    14808 fd-recommend-dubbo-consumer.jar
    11369 Jps -Denv.class.path=.:/usr/jdk1.8.0_51/lib/dt.jar:/usr/jdk1.8.0_51/lib/tools.jar -Dapplication.home=/usr/jdk1.8.0_51 -Xms8m
    28697 Bootstrap -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -XX:MaxNewSize=687865856 -XX:NewSize=687865856 -Xms1024m -Xmx1024m -Djava.endorsed.dirs=/usr/local/tomcat/tomcat-fd-listserv/endorsed -Dcatalina.base=/usr/local/tomcat/tomcat-fd-listserv -Dcatalina.home=/usr/local/tomcat/tomcat-fd-listserv -Djava.io.tmpdir=/usr/local/tomcat/tomcat-fd-listserv/temp
    9449 KnApplistTagConsumer
    7818 dubbo-admin-0.0.1-SNAPSHOT.jar
    32748 Bootstrap -Dnop -Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager -Djava.security.auth.login.config=/home/testknpub/tomcat/kerberos_files/kafka_client_jaas.conf -Djava.security.krb5.conf=/home/testknpub/tomcat/kerberos_files/krb5.conf -XX:MaxNewSize=687865856 -XX:NewSize=687865856 -Xms1024m -Xmx1024m -Djava.endorsed.dirs=/home/testhadoop/tomcat/tomcat_18001/endorsed -Dcatalina.base=/home/testhadoop/tomcat/tomcat_18001 -Dcatalina.home=/home/testhadoop/tomcat/tomcat_18001 -Djava.io.tmpdir=/home/testhadoop/tomcat/tomcat_18001/temp
