Hi Marcin!

You may monitor ngrok's

- log files
- binaries
- configuration files
- init files
- the running process
- TCP ports
- and functional tests as you mentioned, you may check public_url in a  
shell script

see all my configs  
https://github.com/szepeviktor/debian-server-tools/tree/master/monitoring/monit/services
aruba-serclient_script is a very simple example:
/usr/bin/lsof -p "$(cat /run/serclient.pid)" | grep -w "/dev/ttyS1"

so
curl --silent "http://127.0.0.1:4040/api/tunnels/ssh"; | jq -r  
'.public_url' | grep -F 'tcp://0.tcp.eu.ngrok.io:'

adding "if changed status then alert" to monit will alert you.

All the best!
