Macros such as $DATE, etc. +## are expanded at runtime. For example, to override the sender, use: +# +# set mail-format { from: monit@foo.bar } +# +# +## You can set alert recipients whom will receive alerts if/when a +## service defined in this file has errors. Alerts may be restricted on +## events by using a filter as in the second example below. +# +# set alert sysadm@foo.bar # receive all alerts +# +## Do not alert when Monit starts, stops or performs a user initiated action. +## This filter is recommended to avoid getting alerts for trivial cases. +# +# set alert your-name@your.domain not on { instance, action } +# +# +## Monit has an embedded HTTP interface which can be used to view status of +## services monitored and manage services from a web interface. The HTTP +## interface is also required if you want to issue Monit commands from the +## command line, such as 'monit status' or 'monit restart service' The reason +## for this is that the Monit client uses the HTTP interface to send these +## commands to a running Monit daemon.
