[Pacemaker] crm_mon with sending mails

[Tom Tux]

Hi all,

I started "crm_mon" in the background to send me mails when a
cluster-event occurs:
crm_mon -d -H [smtp-server] -T [my_mailaddress]

But when I manually stop or start a resource or take one node offline
and online again, I did not receive an email.

My question hereby:
On which cluster-events will the crm_mon send emails? Can I define, on
which events the crm_mon has to mail me?

Thanks a lot.
Tom
