监控 Apache ActiveMQ 消息中间件
对 Apache ActiveMQ 消息中间件的运行状态，节点，Topic等相关指标进行监测。
使用协议：JMX
监控前操作
您需要在 ActiveMQ 开启
JMX服务，HertzBeat 使用 JMX 协议对 ActiveMQ 进行指标采集。
修改安装目录下的
conf/activemq.xml文件，开启JMX在
broker标签中添加userJmx="true"属性<broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}" useJmx="true">
<!-- others -->
</broker>修改安装目录下的
bin/env文件，配置JMX 端口 IP等将如下原配置信息
# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.port=11099"
# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"
# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.access.file=${ACTIVEMQ_CONF}/jmx.access"
# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote"更新为如下配置，⚠️注意修改
本机对外IP# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.password.file=${ACTIVEMQ_CONF}/jmx.password"
# ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.access.file=${ACTIVEMQ_CONF}/jmx.access"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.port=11099"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.ssl=false"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote.authenticate=false"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Djava.rmi.server.hostname=本机对外IP"
ACTIVEMQ_SUNJMX_START="$ACTIVEMQ_SUNJMX_START -Dcom.sun.management.jmxremote"重启 ACTIVEMQ 服务，在 HertzBeat 添加对应 ActiveMQ 监控即可，参数使用 JMX 配置的 IP 端口。
