Alarm
There is a lot going on in the system with WCUs uploading data and many there are thousands of WCUs doing all sorts of things. Keeping track if all this is a tough job and this is where the alarms are at your disposal. This view is meant to collect all relevant information regarding the status of individual WCUs. Of course, it can keep status of more than WCUs but at this very moment that is what is there.
As default, the alarms from the last 24 hours are kept in the list. The list is updated automatically with new alarms once every 10 minutes. Alarms already on the list are not removed, hence, over time there will be alarms from over 24 hours ago. A figure of the alarm panel is on the right. An alarm consists of five parts, a resource identifier, a time, a message, a severity and a category.
A resource identifier can basically take any form, it is a string that identifies the source of the alarm. In the case to the right there are three distinct WCU resources with id wcu::04-1B-94-00-20-8C, wcu::00-09-D8-02-B7-4A and wcu::04-1B-94-00-20-76.
Time is simply at what time the alarm was triggered.
A message is a textual description of what happened. In this case it was because certificates are about to expire. The message looks as follows: 'Certificate expires on 20181019-184056 +02:00'.
Severity is a way to communicate the urgency.
Category is a way to categorize an alarm. This is particularly useful for searching.
