How do you set different e-mail subjects per alert?

[Adam Nielsen]

Hi all,

I have a bunch of tests which do somewhat cryptic things (like checking 
timestamps of log files), so because a check failure doesn't immediately 
explain what the problem is I would like to include a more descriptive 
message in the e-mail subject of the alert.

Looking at the Monit documentation, I should be able to do something 
like this:

check file import.lastrun with path /var/lib/import.lastrun
  if timestamp > 28 hours then
    alert address@hidden with mail-format { subject: "XYZ import error" }

Unfortunately this gives me the following error:

  /etc/monit/monitrc:3: Error: syntax error 'address@hidden'

I'm not sure why it's rejecting the e-mail address, as that's the way 
the command is listed in the documentation.  I don't really want to 
specify the e-mail address anyway, as I want all alerts to go to the 
same place, as specified by the "set alert" command.

So if I leave the address off, hoping it will use the default, I then 
get this error:

  /etc/monit/monitrc:3: Error: syntax error 'mail-format'

I'm a bit confused as I can't see what I am doing differently to the 
examples in the docs.

Can anyone advise how to change the e-mail subject for specific alert 
messages?

Many thanks,
Adam.
