escalations for passive checks?

[Andrew Laden]

Escalations are based entirely on alert received/processed by nagios,
not on time.

For active checks, the time factors control how often the service is
checked, and therefore how often an alert is sent to nagios. 
For passive checks, this obviously doesn't hold.

If you want to get around this, you can try to craft an active check
that gets the current status of the item, and "repeats" it back to
nagios, thus creating another alert. I've never tried this though.
