I'm not running heartbeat at the site in question, and wasn't thrilled
about setting  it up between the director  and two  realservers.  More
importantly,  Mon is generalizable  to  an org-wide monitoring  system
(which heartbeat is  not).   Mon has  a wider  range of service  check
scripts and alerts than ldirectord has and is therefore more flexible.
If somebody wanted to monitor ipvs but take action ONLY by alpha pager
(i.e.  *not* modifying ipvs) then  Mon would be  more appropriate than

% You are in a maze of twisty passages, all alike.
