How to restart and alert if condition matches in Monit

You can disable this alert by setting up a local alert statement. This is thoroughly documented here: http://mmonit.com/monit/documentation/monit.html#setting_a_local_alert_statement

This should do it:

check process blop with pidfile /.../blop.pid
    alert recipient@address.com but not on { pid }
    start program = "..."
    stop  program = "..."

From the monit manpage:

alert foo@bar with reminder on 1 cycle

This will repeat the alert every time the process check repeats once it is in a failed state (eg, quite a lot). You may want to set this so it only reminds you ever hour or less

This seems to be set where you'd set an alert destination, rather than in the check stanza. However, you can specify an alert destination for individual checks/services, as well as the global one.

check filesystem datafs with path /dev/sda1
  alert foo@bar on { resource } with reminder on 10 cycles
  if space usage > 80% for 5 times within 15 cycles then alert
