Yes, the counter is in-memory and not written to disk. A reboot or a
restart of collectd will reset it to zero.

No, it doesn't.

No, that's not the case. The counter is only ever increased by collectd.

Can you tell me what parts of the documentation you were checking, so I
can (try to) clarify the behavior there? Thanks :)
