Introduction
The basic workings jobs of checks are described here.

Checked are done by the Shinken Enterprise daemon at regular intervals, as defined by the check interval and retry interval check definitions.

Services State Changes
When Shinken Enterprise checks the status of services, it will be able to detect when a service changes between OK, WARNING, UNKNOWN, and CRITICAL states and take appropriate action. These state changes result in different state types (HARD or SOFT), which can trigger event handlers to be run and notifications to be sent out. Check state changes can also trigger on-demand host checks. Detecting and dealing with state changes is what Shinken Enterprise Enterprise is all about.
When check change state too frequently they are considered to be “flapping". Shinken Enterprise can detect when services start flapping, and can suppress cancel notifications until flapping stops and the service's state stabilizes. More information on the flap detection logic can be found on the flapping page.
