Component Update - Status

- Align the component status field with the Nagios standard
  0=ok, 1=warning, 2=critical
- Modify existing modules to report these status' (Cisco-OTV)
- Add/Modify Alerting Macros to use these status'
- Add the a component status widget
- update edit page to report these status'

 ## <a name="alert">Alerting</a>
 
 It is intended that discovery/poller modules will detect the status of a component during the polling cycle.
-If you are creating a poller module which can detect a fault condition simply set STATUS to 0 and ERROR to a message that indicates the problem.
+Status is logged using the Nagios convention for status codes, where:
+    0 = Ok,
+    1 = Warning,
+    2 = Critical
 
+If you are creating a poller module which can detect a fault condition simply set STATUS to something other than 0 and ERROR to a message that indicates the problem.
 
 To actually raise an alert, the user will need to create an alert rule. To assist with this several Alerting Macro's have been created:
 
-- ```%macro.component_alert``` - A component that is not disabled or ignored and in alert state.
-- ```%macro.component_normal``` - A component that is not disabled or ignored and NOT in alert state.
+- ```%macro.component_normal``` - A component that is not disabled or ignored and in a Normal state.
+- ```%macro.component_warning``` - A component that is not disabled or ignored and NOT in a Warning state.
+- ```%macro.component_critical``` - A component that is not disabled or ignored and NOT in a Critical state.
 
 To raise alerts for components, the following rules could be created:
 
-- ```%macros.component_alert = "1"``` - To alert on all components
-- ```%macros.component_alert = "1" && %component.type = "<Type of Component>"``` - To alert on all components of a particular type.
+- ```%macros.component_critical = "1"``` - To alert on all Critical components
+- ```%macros.component_critical = "1" && %component.type = "<Type of Component>"``` - To alert on all Critical components of a particular type.
 
 If there is a particular component you would like excluded from alerting, simply set the ignore field to 1.
