The Monitoring tab is a dashboard that displays
summary widgets of all your SD-WAN firewall and Prisma Access health
metrics. This tool provides actionable intelligence about the activity
on your SD-WAN network by enabling you to quickly identify applications
or links experiencing performance issues. You can view path quality
and link performance for all VPN clusters—for a specific VPN cluster—within
a specified period of time.
At a glance, you can view the total number of VPN clusters with
branch or hub firewalls that are experiencing impacted application
performance and those that are healthy. You can view the following
application and link health states for VPN Clusters:
App Performance
Impacted—One or
more applications in the VPN cluster for which none of the paths
have jitter, latency, or packet loss performance that meet the specified
thresholds in the Path Quality Profile in the list of paths from
which the firewall can choose.
OK—Applications in the VPN cluster are healthy and
experiencing no or below the specified thresholds for the jitter,
latency, or packet loss performance in the Path Quality Profile.
Link Performance
Error—One or more sites in the VPN cluster have connectivity
issues such as when a tunnel or a virtual interface (VIF) is down.
Warning—One or more sites in the VPN cluster have links with
bandwidth (supported in PAN-OS
11.2.0 with SD-WAN plugin 3.3.0 and later releases),
jitter, latency, or packet loss performance
measurements that compare unfavorably to a moving seven day average
value.
OK—Links in the VPN cluster are healthy and experiencing no or
below the specified thresholds for the
bandwidth (supported in PAN-OS
11.2.0 with SD-WAN plugin 3.3.0 and later releases),
jitter, latency, or packet loss performance in
the Path Quality Profile.
Beginning with PAN-OS 11.2.0, SD-WAN
plugin 3.3.0 and later releases support 'bandwidth' which is the primary measure
of the link performance.
If a hub or branch firewall have an application configured with
Forward Error Correction, an Error Correction Initiated message
is displayed to notify you that the hub or branch firewall detected
and corrected errors in transmitted data.
