No, I haven't.  I view my problem as being TOO MANY different sources to
begin with :-).

Sounds like zabbix is out -- no PHP or Web server on the system involved,
and I can't install one (in-service production box).

I've never heard of a "monitor" command for unix, and there isn't one on
this Centos installation.  I'm open to persuasion here.  And I haven't
looked into whether this info is directly accessible in the proc
filesystem or something yet either.
