Hello @tsaleh,

There actually is a reason. `Bosh::Monitor::Events::Alert` instances don't actually have metrics (see https://github.com/cloudfoundry/bosh/blob/master/bosh-monitor/lib/bosh/monitor/events/alert.rb#L87) and so this code doesn't actually need to apply to them.

We'll refactor the code to be clearer on this point and add the new commit to this PR.
