A potential customer is asking us about how much hosts licences do them need to monitor some aws cloudwatch services (RDS, Dynamo, API Gateway) etc, them have running.
Anyone have some idea about this?

One per host that they configure in XI. However, each configured host can monitor any number of services.

In case it helps - we map multiple CloudWatch Alarms to a single Nagios Host definition, linking them by simple packing of the CloudWatch Alarm Name. The different Metrics show up as Services. For example a single RDS shows up as one Host in Nagios, with Services representing the Metrics like CPUUtilization, DatabaseConnections, DiskQueueDepth, etc.
We even go as far as creating Host & Service Groups automatically based on the CloudWatch Alarm Name.
(If Amazon would ever develop Tags for CloudWatch Alarms we wouldn't have to pack the Name field, but it's a work-around that's only mildly annoying.)
I mention this with regard to your host sizing question because for us the number of Host objects relates to the number of actual AWS resources, not the number of CloudWatch Alarms monitoring those resources.

Thanks stefanw!
mvergara, do these answer your question or is there anything we can clear up for you?
