Wrapping up 1: ICMP health checks with netwatch.If you’re the impatient type, or just looking for a DNS monitoring solution for Pi-hole, skip ahead to the end. Using this problem as an example, let’s take a look at several of the monitoring tools available in RouterOS and how to use them in a script. This wouldn’t eliminate the need to disable/enable WiFi on client devices, but it would 1) restore the network to a working state automatically and 2) notify me that there was a problem. I wanted to create a script to check if the Pihole was available and if not, update the local DNS to remove the Pi-hole until it was online again. My home router runs Mikrotik RouterOS, which offers a scripting engine that can be used to automate device configuration, perform scheduled tasks, etc. While performing some recabling recently I accidentally disconnected the Pi-hole from the core switch, much to the chagrin of everyone else using the internet in the house. I’ve used Pi-hole on a Raspberry Pi as a DNS resolver and adblocker in my home network for several years.
