Machines are monitored using Collectd thresholds and notifications.

Collectd gathers metrics and checks collected values agains a configured list of thresholds. If a value is outside of the acceptable range, a new alert is raised and sent to Dartagnan instance.

Alerts can be generated by Collectd thresholds, cron jobs or even external daemons like NMS which constantly monitor the status of registered services.
