I am trying to enable the HA between the main poller and standby poller. I am not sure which DNS to select, our environment has a linux based DNS. Both of these servers are hosted in Azure cloud. What would be the best way to enable HA. If i am going with DNS type- Other then Solarwinds recommends a script to be created which can help in updating the DNS record, if someone has the script, can you please help me with the same.
