jmx

after reading and trying a lot around, I have to ask if anyone has a solution for my problem. I am trying to set up some Tomcats (V6) behind a firewall. This is no big deal - but I want to monitor them via JMX. I read the TC docu and came across the JMXRemoteLifecycleListener . My test TC installation is set up exactly as stated in the above link. Thus I don't get a connection from one host in our network to another. Additionally a third, random port is open every time I start TC. In my server.xml the listener is activated <Listener className="org.apache.catalina.mbeans

I spent some time checking out JBoss AS7 today. I am impressed with what I have seen so far but I noticed that good ol' JMX-Console no longer exist. Does anyone know why it was left out? I understand that I can connect through JConsole, MC4J etc. but is there an alternative that would provide web based access to the deployed MBeans? According to this thread (see below), there will be no such thing. Server management will be achieved in another way - via JBoss native interfaces. There will be, however, a compatibility layer exposing JBoss services through JMX. http://community.jboss.org/thread

My specific question has to do with JMX as used in JDK 1.6: if I am running a Java process using JRE 1.6 with com.sun.management.jmxremote in the command line, does Java pick a default port for remote JMX connections? Backstory: I am currently trying to develop a procedure to give to a customer that will enable them to connect to one of our processes via JMX from a remote machine. The goal is to facillitate their remote debugging of a situation occurring on a real-time display console. Because of their service level agreement, they are strongly motivated to capture as much data as possible and

因项目需要，Zabbix要监控SQL server的连接数，MySQL以及tomcat，下面是对监控上述item的简要介绍。 1. SQL server连接数 　　1.1 SQL server连接数 　　1. SQL Server查询当前连接数 　　2. Sql Server当前并发连接数的查看方法 　　3. 亲测SQLServer的最大连接数 　　4. SQL SERVER用户数、连接数、连接池License SELECT * FROM [Master].[dbo].[SYSPROCESSES] WHERE [DBID] IN ( SELECT [DBID] FROM [Master].[dbo].[SYSDATABASES] WHERE NAME='PointCheckSystem' ) select hostname,count(*) hostconncount from master.dbo.sysprocesses group by hostname order by count(*) desc微软在MSDN上对最大连接数的定义是：“默认是0，代表不限制，但最大连接数是32767”。 　　1.2 Zabbix监控SQL server 　　1. Zabbix监控sqlserver 　　2. Zabbix监控 Windows SQL Server 可选方案1.

I should connect to a java program on localhost jvm using JMX. In other words I want to develop a JMX client to config a java program on localhost. Don't recommend using JConsole! JConsole is not suitable because it is general JMX client and have negative effect on main program performance. Samples on oracle site use RMIConnector and host:port params but I don't know: where should set jmx port? JConsole have an option to connect to java processes by PID. But I don't find any method in JMX api that have PID as input param. We use something like the following to programatically connect to our

1.在server2上安装jdk [root@server2 ~]# rpm -ivh jdk-8u121-linux-x64.rpm 2.解压tomcat软件到/usr/local/目录下 [root@server2 ~]# tar zxf apache-tomcat-8.5.24.tar.gz -C /usr/local/ 3.制作软连接 [root@server2 ~]# cd /usr/local/ [root@server2 local]# ln -s apache-tomcat-8.5.24 tomcat [root@server2 local]# ls apache-tomcat-8.5.24 etc include lib64 sbin src bin games lib libexec share tomcat 4.编辑 catalina.sh 文件，添加JMX参数 [root@server2 local]# cd tomcat/ [root@server2 tomcat]# ls bin lib logs RELEASE-NOTES temp work conf LICENSE NOTICE RUNNING.txt webapps [root@server2 tomcat]# cd bin/ [root@server2 bin]# vim catalina.sh
