05/24/2023, 1:26 AMhmm. i am not sure (never done this myself) but i guess you would need to add it to an override on
druid.indexer.runner.javaOptsdruid.indexer.runner.javaOptsArray-Ddruid.monitoring.monitors=...Gian Merlino
05/24/2023, 1:27 AMthe issue is the MM itself cannot do queries so it can't load a query monitor
Gian Merlino

05/24/2023, 1:27 AMthis is a little awkward, perhaps we should make this better by adding a system to allow monitors to be configured the same on all node types, and ignore the ones that aren't applicable to the node type

05/24/2023, 1:27 AMwe offer a similar capability for extension modules
