Thanks for your reply, Daniel. Regarding the group list, do you mean that if the group of the source cluster has not committed an offset (the group does not exist or the group has not committed an offset to the topic being replicated), then the current metric cannot be collected? Then this involves the question of motivation: Do we want to monitor the topic list and group list we configured, or the topic list and group list that are currently being replicated? If it is the latter, shouldn't it be detected for a group that has not committed an offset? I don't know if I understand correctly.
