After a clean install of OpenNMS 22, almost all JMX stats for the minions have disappeared, compared to the stats from 20.1.0.
By enabling debug logging in one of the minions, it reports a bunch of missing objects every time OpenNMS tries to collect data:
ObjectName java.lang:type=GarbageCollector,name=MarkSweepCompact is not registered. ObjectName org.apache.camel:context=org.opennms.core.ipc.rpc.camel-impl,type=routes,name="RPC.Server.Detect" is not registered. ObjectName org.apache.camel:context=org.opennms.core.ipc.rpc.camel-impl,type=routes,name="RPC.Server.DNS" is not registered. ObjectName org.apache.camel:context=org.opennms.core.ipc.rpc.camel-impl,type=routes,name="RPC.Server.PING" is not registered. ObjectName org.apache.camel:context=org.opennms.core.ipc.rpc.camel-impl,type=routes,name="RPC.Server.PING-SWEEP" is not registered. ObjectName org.apache.camel:context=org.opennms.core.ipc.rpc.camel-impl,type=routes,name="RPC.Server.Poller" is not registered. ObjectName org.apache.camel:context=org.opennms.core.ipc.rpc.camel-impl,type=routes,name="RPC.Server.SNMP" is not registered.
It seems like most of the MBeans have changed. These are the closest objects I could find in the current (22.0.4) list of MBeans:
