Re-sent Alert ( with reminder on )

 * Monit by default sends just one notification

i.e.

# Notified each tenth cycle

# Global
set alert [email protected] not on { instance } with reminder on 10 cycles

OR

# Per Service
CHECK HOST
    alert foo@bar with reminder on 10 cycles
    IF ...
       ...
       ...
    THEN alert

Multiple email recipients

settings

alert [email protected]
alert [email protected]

mail-format

set mail-format {
     from: [email protected]
 reply-to: [email protected]
  subject: $SERVICE $EVENT at $DATE
  message: Dear Sir

    Monit $ACTION $SERVICE at $DATE on

    $HOST: $DESCRIPTION.

Yours sincerely,
monit
}

設定某 Service 不出 Alert 某 E-Mail

i.e.

set alert foo@bar

check process p1 with pidfile /var/run/p1.pid
  noalert foo@bar

Event Filter

Settings

[1]

set alert foo@bar only on { Event1, Event2, ... }

[2]

set alert foo@bar but not on { Event1, Event2 ... }

Event:

• instance   # email content: "Monit instance changed"
• nonexist   # email content: "Does not exist""
• ...

Event Queue

If no mail server is available, Monit can queue events in the local file-system for retry until the mail server recovers.

The event queue is persistent across Monit restarts

By default, the queue is disabled and if the alert handler fails, Monit will simply drop the alert message.

# 當沒有 "set alert [email protected]" 時就沒有 E-Mail Alert
# slots = queue size = store up to number event messages

SET EVENTQUEUE BASEDIR <path> [SLOTS <number>]
