Alert for disconnected

L4 Transporter

Hello -

Can AIOps alert me when a device has become disconnected from Panorama?  If not, is there some other method of being alerted to this?

Hello @RobertShawver

 

thank you for post.

 

I do not know answer for AIOps. Based on documentation only disconnection from CDL is alerted: https://docs.paloaltonetworks.com/aiops/aiops-for-ngfw/alerts-toc/view-service-alerts. 

 

Potentially you can set an alerting based on system logs. Each time a Firewall is disconnected from Panorama, it generates below critical logs:

If you set in: Panorama > Log Settings > System > Add > Filter: ( description contains 'Disconnected from' ), then add email profile for alerting, you can get an email notification.

 

This alerting can however be noisy if you perform Panorama upgrade when all Firewalls will disconnect and reconnect or Firewall in branch location with flapping WAN connection.

 

One alternative that is manual is to go to: Panorama > Managed Devices > Troubleshooting > Select Test: Log Collector Connectivity. After execution, this will give report of log collector connectivity status of all Firewalls. In corner case, when Firewall is registered in Panorama, but does not send logs this is useful to proactively detect it. I let NOC Team to run it once a week just in the case something slipped through fingers.

 

Kind Regards

Pavel
