I wonder if anyone here can assist me to point into the right direction to create simple OutOfBand monitoring solution.
I have already established the ExpressRoute circuit from my Data centre to Azure Regional datacenter.
Requirement: Monitor the OnPremise Network appliances (Gateways, Firewalls and other services IP addresses) from Azure, then send an email alert or trigger alert via PagerDuty.
However, as per this documentation https://learn.microsoft.com/en-us/azure/azure-monitor/platform/agents-overview
I cannot find any way to monitor just a few select IP addresses of network appliances, since it requires Agent install.
I also cannot configure Pingdom service to test my network appliances IP address either.
Thanks in advance.
