Question
Upgrading HiveMQ version from 3.x to 4.x and want to upgrade How can the following plugins be upgraded from HiveMQ 3 to HiveMQ 4?
hivemq-sys-topic-plugin-3.0.0.jar
...
jvm-metrics-plugin-3.1.0.jar
...
etc.
Answer
jvm-metrics-plugin-3.1.0.jar plugin: HiveMQ 4, by default, exposes all JMX metrics on remote port 9010, and
...
the customer can monitor them using
...
the monitoring tools. Hence
...
this plugin is deprecated and
...
is not
...
required anymore.
...
hivemq-sys-topic-plugin-3.0.0.jar plugin: HiveMQ 4 does not support $SYS topics for security reasons. Hence this plugin is not supported with HiveMQ 4.
