This is probably the most useful feature of amtool: the ability to validate the syntax and schema of our Alertmanager configuration file and referenced template files. You can test the check-config sub-command by following this example:
vagrant@alertmanager02:~$ amtool check-config /etc/alertmanager/alertmanager.yml Checking '/etc/alertmanager/alertmanager.yml' SUCCESSFound: - global config - route - 1 inhibit rules - 8 receivers - 1 templates SUCCESS
This type of validation is quite easy to automate and should be done after any configuration change, but before reloading the Alertmanager instance, thereby preventing most types of configuration issues.
