[root@localhost ~]# 

This is more problem e.g. with proc metrics when there might be hundreds of
unrequested instances included (makes harder to use tools like pmrep(1) which
do not allow specifying instances and can theoretically be seen also a
confidentiality issue, i.e., when trying to record only one specific process
information about all running processes is being added to the archive).

The same goes for pmlogextract(1).

Thanks.
