Alarm

Alarm is a task that allows for configuration of alarms on selected devices. The current set of devices support by this task is WeOS 4 and WeOS 5 devices.

Interface components

Each device can configure multiple actions and triggers, as well as enable or disable summary trap.

Actions

When an alarm event occurs, the operator can be informed in a number of ways. This is defined by a specific alarm action that is associated with any given alarm trigger. The alarm action in turn specify one or more alarm targets that will be used to notify the operator.

The available targets vary depending on the WeOS version

WeOS 4

Target	Description
SNMP-Trap	Generate an SNMP trap
Log	Log status change to syslog
LED	Set ON/Status LED
Status-Relay	Control the status relay (digital out)
Port	Control the admin status of a port.
Reboot	Reboot the unit. USE WITH CAUTION!

WeOS 5

Target	Description
SNMP-Trap	Generate an SNMP trap

Port selection

There are some presets available to make it easier to select the correct ports. The presets are as follows:

info

Only presets that are applicable to the current device and configuration will be shown.

Triggers

An alarm trigger will monitor a provided alarm source and define the conditions for when specific alarm events occur, in other words, when the trigger becomes active (alarm situation) or inactive (normal operation).

Exactly which triggers are available depends on the device. The list you see in WeConfig is based on the list of supported trigger types the devices themselves provide.

These are all the triggers that WeConfig currently supports:

Common parameters

All triggers have a set of common parameters:

Parameter	Description
Enabled	Enables or disables the trigger.
Active Severity	Specify the severity level of active alarm events detected by this trigger.
Inactive Severity	Specify the severity level of inactive alarm events detected by this trigger.
Action	The action to be invoked when this trigger detects an alarm event.

Serverity levels are defined as follows:

Severity Level	Description
Emergency	System is unusable
Alert	Action must be taken
Critical	Critical conditions
Error	Error conditions
Warning	Warning conditions
Notice	Significant condition
Info	Informational message
Debug	Debug-level message
None	No severity
