How to detect an old consumer

Hello,

I want to detect old consumers in my kafka servers. Is there any tool to
see the last date when they connected? I tried in kafka-manager but I only
have the consumer group and its offset, which is not useful to detect that
problem...

Thanks in advance!

Old consumers use ZK to store their offsets.  Could you leverage the
timetamps of the corresponding znodes [1] for this?
