when check the cluster status all three nodes are able to see and policy
i compared both version management plugin enabled.
enabled rabbitmq-plugins rabbitmq_management and restarted services.

I will convert this issue to a GitHub discussion. Currently GitHub will automatically close and lock the issue even though your question will be transferred and responded to elsewhere. This is to let you know that we do not intend to ignore this but this is how the current GitHub conversion mechanism makes it seem for the users :(

A newly joined node will emit stats after a period of time. Before that happens, it won't have any stats to report and the UI won't have any to display.

Different cluster nodes may have different set of plugins or settings, which can also affect what stats are collected or how often.

Finally, mixed version clusters (such as this 3.8.2 and 3.9.8 cluster) are not guaranteed to provide every feature or be compatible in every way. They don't have any major incompatibilities but 3.8 nodes obviously won't be able to interpret some 3.9-specific data, for example.
