Alarms

Alarm is an emergency situation that was detected on an object or a link during monitoring process.

Detected alarms are displayed in the alarms interface. You can also display historic alarms in the alarms interface. You can open alarms page with the button on the views panel.

You can configure alarm levels on the Incidents page of the system configuration.

You can manually or automatically clear an alarm to move it to alarm history.

Alarms generation

The system has two ways of generating an alarm – either setting an entity to an alarm state or meeting an alarm generation conditions.

Set object to an alarm state

The system generates an alarm for every entity whose state is set to one with defined severity.

In this case, every object can generate only one alarm.

You can set alarm severity can in the System configuration window, on the States tab.

By default the following states have pre-set alarm severity:

ALARM → ALARM
OVERLOADED → WARNING
NO DATA → MAJOR
DOWN → MAJOR

The incident will be cleared - CLEARED - if the object changes its state to any without selected alarm severity.

When an object inherits an alarm state from its children, a new alarm for the parent object is not generated.

Alarm generation conditions

The system can generate an alarm when object’s Alarm generation conditions are met.

In this case, a single object can generate multiple alarms.

Incident functionality is optional and disabled by default. To enable it, set the following parameters:

in the section Server of the server configuration file:
```
"conditional_incidents_enabled": true
```
in the client configuration file:
```
enableConditionalIncidents: true
```

If alarm generation conditions for the object are set, then the alarm generation on state change will be disabled for this object.

The alarm will be cleared if no Alarm generation conditions defined for this entity are met and the additional clear conditions, if present, are met.
