Re: false alerts on process resources

[Jay Shaughnessy]

This does not seem like an issue with alerting.  The resource is being 
reported with DOWN availability and so you get the alert. (Same with UP, 
I guess).  So it really is a question of why DOWN was reported if, as 
you say, the resource seems to be UP the entire time.  It must have to 
do with the component's inquiry into the Process component...
