need to setup a cron job or scheduele, as it runs immediately after the normal
poller automatically.

Threshold Tab displays current thresholds, current value, triggered status, and host status
High/Low settings as well as adjustable baseline monitoring.
Global and individual email notification for triggered thresholds.

Install just like any other plugin, just throw it in the plugin directory,
in a folder called thold.
