You can confirm the latest MP version in the [ALL VERSIONS] sticky post - veeam-management-pack-for-microsoft-system-center-f1/current-version-is-7-0-july-22nd-2014-t22648.html
If you have all .2218 MPs, then I think you have the GA version of 8.0, with no updates.
If your goal is to track a vCenter alarm, which targets VMs, then as Sergey said I recommend you wait for Update 4. It is cumulative, so you will get all previous updates 1-3 when you apply Update 4.
If you want to implement an alert now, then you can enable the event logging as Sergey suggested. In general events are not a heavy load on our Veeam Collector - it is performance data which is the bulk of the payload.
However, events will be an additional load, of course. And also you will have extra manual steps to create your own SCOM alerting monitor/rule for this event.
Unless your need for this alert is urgent I would recommend waiting for our Update 4. Then you will have a simple method to create any SCOM monitor to track any vCenter Alarm. We cannot guarantee release dates in general, but Update 4 should ship next month.
