global alert statement

[Martin]

Hi,

here is implementation of global alert statement. It allows to define global 
list of alert recipients with optinal custom message format and event selection 
list (as usual in per service alert definition).

In the case of any event on any monitored service monit will send the alert to 
this recipient list in addition to the mailinglist defined by the service 
localy (conjunction). If the same recipient is defined twice (globaly and 
localy), monit will send only one alert. Localy (per service) defined alert 
recipient overrides global recipient in the case of conflict.

The syntax is the same as normal alert statement, the only exception is that it 
is prefixed by 'set' word (like other global variables). More then one instance 
of this statement is allowed, so you can write for example:

  set alert address@hidden    #receive all events of all services
  set alert address@hidden on { uid, gid, checksum, permission, timeout } 
#receive security events of all services
  ...
  check file myfile with path /my/file
     if timestamp > 15 minute then alert
     alert address@hidden #receive all events of this service
     alert address@hidden on { timestamp } with mail-format { subject: Alarm! } 
#overrides global registration

  check file yourfile with path /your/file
     if timestamp changed then alert
     alert address@hidden #receive all events of this service

  check file theirfile with path /their/file #there is no local recipient 
definition
     if timestamp changed then alert


If you agree, i will check it in.
