Another question I have is about the restoration of monitoring data to a primary monitoring node that has temporarily failed. As per documentation it states that a manual backup should be taken from the secondary node and restored to the primary to essentially provide the missing events during the outage. I have a couple of questions about this process:
1. What happens when the primary monitoring comes back online - does it sync up with the secondary monitoring node effectively overwriting the events the secondary has or does it just continue on its merry way?
2. To restore data to the primary monitoring node do you need to de-register the primary before restoring the backup taken from the secondary and re-join it to the deployment or do you just restore from the primary admin GUI? As far as I can see this still means that there will be a hole in the data for the period of time it takes to restore from backup.
