In NetBrain, we have One IP table which maintain the ip to mac mapping. I want to make observability dashboard which will highlight the alert in dashboard if ip to mac entry change for particular to ip address.

Not able to find way to have one ip table data collection once day / as per our schedule and alert if changes happened.

Hi ​@harishchandras 

Do you want to check the mac for management ip of device or all IP as device will have many MAC as per interfaces. For only Mgmt Ip, I called the one ip table inside intent and stored the value of mac inside a variable. Then during next execution we can compare the past value against present and raise alert in case of difference.
