Can not get aggregate grpsum working

[lintmint]

I'm monitoring several nodes with the below item

jmx[\"kafka.server\":type=\"BrokerTopicMetrics\",name=\"AllTopicsBytesInPerSec\"][OneMinuteRate]

I would like to also monitor the sum across all nodes but I can not seem to get that working. I've tried each of the below keys for the Zabbix Aggregate type item with no luck. The name of the aggregate item doesn't even show up in the latest data screen

[FONT="Courier New"]grpsum["Host Group","jmx[\"kafka.server\":type=\"BrokerTopicMetrics\",name=\"AllTopicsBytesInPerSec\"][OneMinuteRate]",sum,0]
grpsum["Host Group","jmx[kafka.server:name=AllTopicsBytesInPerSec][OneMinuteRate]","sum",0]
grpsum["Host Group","jmx[kafka.server:name=AllTopicsBytesInPerSec][OneMinuteRate]","last",0]
grpsum["Host Group","jmx[\"kafka.server\":name=\"AllTopicsBytesInPerSec\"][OneMinuteRate]",last,0]
grpsum["Host Group","jmx[\"kafka.server\":name=\"AllTopicsBytesInPerSec\"][OneMinuteRate]","last",0]
grpsum["Host Group","jmx[\"kafka.server\":type=\"BrokerTopicMetrics\",name=\"AllTopicsBytesInPerSec\"][OneMinuteRate]","last",0]
grpsum["Host Group","jmx[\"kafka.server\":name=\"AllTopicsBytesInPerSec\"][OneMinuteRate]","last",0]
grpsum["Host Group","jmx[\"kafka.server\":\"BrokerTopicMetrics\"][\"AllTopicsMessagesInPerSec\"][OneMinuteRate]","last",0][/FONT]

Any tips would be greatly appreciated.
