由jolokia代理連接到遠程cassandra JMX

Question

我嘗試通過jolokia（jolokia site）代理和hawt（hawt site）程序連接到遠程cassandra JMX，但是我不能。請指導我在jolokia和hatw程序中需要哪些配置和更改。

我打算在這裏出去走走，並建議您在cassandra配置中未啓用遠程JMX。按照datastax documentation，你應該修改cassandra-env.sh並啓用remote_jmx（設置$LOCAL_JMX = no），並編輯這些行，以滿足您的需求：

LOCAL_JMX=no 

if [ "$LOCAL_JMX" = "yes" ]; then 
    JVM_OPTS="$JVM_OPTS -Dcassandra.jmx.local.port=$JMX_PORT -XX:+DisableExplicitGC" 
else 
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.port=$JMX_PORT" 
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.rmi.port=$JMX_PORT" 
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl=false" 
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.authenticate=true" 
    JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.password.file=/etc/cassandra/jmxremote.password" 
# JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.keyStore=/path/to/keystore" 
# JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.keyStorePassword=<keystore-password>" 
# JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.trustStore=/path/to/truststore" 
# JVM_OPTS="$JVM_OPTS -Djavax.net.ssl.trustStorePassword=<truststore-password>" 
# JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl.need.client.auth=true" 
# JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.registry.ssl=true" 
# JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl.enabled.protocols=<enabled-protocols>" 
# JVM_OPTS="$JVM_OPTS -Dcom.sun.management.jmxremote.ssl.enabled.cipher.suites=<enabled-cipher-suites>"
