So hobbit with the xxx events (running every 5m) did provide enough  
information to indicate an intermittent problem with DNS?

Things running every 5m will collide with a problem that happens for  
a minute frequently enough to 'show up on the radar'

But every site has different requirements.  It's just been my  
experience that sampling more frequently than 5m hits the knee-bend  
of diminishing returns.  It also increases the potential for state  
changes, which chews up the filesystem with the history info.

ymmv
