Alarm prioritization, muting, and auto-close
Last modified:
About alarm prevention
Alarm cascading means that one alarm is the root cause of a series of subsequent alarms. To prevent unnecessary alarms, VCOM applies the following logic:
Communication loss, total outage, and misproduction alarms
Alarms for dependent components are automatically prevented.
Open data outage alarms
All alarm types except communication loss are prevented for the same component.
Exception: If the data outage alarm occurs at the system level, the specified alarm types are prevented for all components.
Open total outage alarms
Total outage, misproduction, and string alarms are prevented if the affected component depends on the alarm-triggering component.
Examples
A system-level total outage will prevent total outage alarms from dependent components.
An inverter-level total outage means all dependent devices and their inputs will be muted.
Examples of alarm prevention
About muting
You can mute alarms for specific components to avoid undesired or unnecessary alarms during a defined period.
When the muting duration ends, monitoring of the relevant components will continue as normal and the muting will have the status Archived in the muting overview.
Mute a component
Steps
Navigate to the Alarms portlet.
Select
Mute affected component next to the relevant alarm.A window opens. The affected component and its dependent components will be shown.
Enter how long the muting should last and an (optional) reason.
Select
Mute component.The muting will be visible under
System configuration > Monitoring > Muting and prioritization.
Further options
Edit: change the muting end date or reason
Resume monitoring: End the muting before the defined duration ends.
About auto-close
The Auto-close feature automatically closes alarms of any type if the same error does not occur again after a user-defined period. It is intended to ensure resolved alarms "disappear" automatically.
Note
This feature was previously called Autopilot.
Configure auto-close
Prerequisites
You have set up at least one alarm
Steps
On the sidebar at the system level, hover over the system for which you want to set up auto-close.
Select
Open system configuration > Monitoring > Muting and prioritization > Auto-close.Activate the check box and select a time interval after which alarms will automatically be closed.
Note
You can view which alarms were automatically closed in the Alarms portlet. Filter the alarms by Status > Closed alarms.
