Previously, the alarm notification contained only a stringified
reason. This change adds a JSON formatted reason why the alarm changed its
state to the notification.
New notification:
{
"alarm_id": "0ca2845e-c142-4d4b-a346-e495553628ce",
"current": "alarm",
"previous": "ok",
"reason": "Transition to alarm due to 1 samples outside threshold, most recent: 99.4"
"reason_data": {
"type": "threshold",
"disposition": "outside",
"count": 1,
"most_recent": 99.4
}
}
It also improves the reporting of OR-combination alarms. Previously the
reason said something like "At least one alarm in xx,yy,zz in state alarm".
Now only the offending alarms are listed.
