RouterOS Italia

Actually there are two scripts. The first one is the main script for monitoring arbitrary RouterOS parameters. It uses the second auxiliary script for logging.

Add both scripts to your RouterOS. Make sure they are named as "monitoring" and "log-up-down". Add the monitoring script to the system scheduler:

Codice:
/system scheduler add name=monitoring on-event=monitoring interval=5s \

    start-date=jan/01/1970 start-time=00:00:00

Check the log messages. You will see the following lines:

Codice:
Check the log messages. You will see the following lines:

Edit the monitoring script to adjust it for your own RouterOS configuration. By default the script monitors the state of three routes and makes log entries when the state is changed, assuming that a failover between two ISP connections is configured. But you can monitor arbitrary parameters and do other actions than just logging.

If you want to receive monitoring notifications by e-mail, just set up RouterOS system logging for that.
