Alerts were introduced in Pacemaker 1.1.15 -- I believe Ubuntu 16.04
has 1.1.14.

Donat: if you can upgrade to a newer Ubuntu, you should be able to get
a version with alerts, which is a better implementation for sending e-
mails than ClusterMon.

If you can't, or you still want to use ClusterMon for the HTML status
updates, my first suggestion would be to make sure that your version of
crm_mon supports the mail-* arguments. It's a compile-time option, and
I don't know if Ubuntu enabled it. Simply do "man crm_mon", and if it
shows the mail-* options, then you have the capability.
