In day-to-day network functioning, many incidents occur that may be a cause
for concern. Prisma SD-WAN identifies these incidents that occur in the network and
classifies them into two types to determine the type of fault.
An alarm is an indication of a fault in the system. Alarms can be
raised and cleared, and can be of the following severity:
Critical – Whole or part of a network is down, and requires immediate
action.
Major – Network is impacted, and needs immediate attention.
Minor – Network is degraded, and needs attention soon.
An alert may or may not be an indication of fault in the network.
An alert is raised when system-defined or customer-defined thresholds are reached.
These alerts and alarms can be viewed from the Events tab of the
Prisma SD-WAN portal.
Alerts and alarms generated in the system are triggered by different types of events,
categorized broadly as hardware issues, software issues, device interface issues, device
registration issues, peering issues, site level issues, tunnel issues, and application
performance issues. These issues, based on the type of event, may originate from the ION
device or the controller.
