Chip Holden commented on TOSCA-216:
-----------------------------------

From Shitao:

I get some commends for clarification:
 
1, in the proposal, does one  metric sample only monitoring one parameter for the application?
If I would like to monitor for example, cpu, memory as well as some application KPIs, do I need to establish many sample metrics, and one for each parameters?
 
2, how do I know which parameter (or parameters in case for my first commends that one metric sample can monitoring several parameters) the sample metric monitoring for? In the tosca.monitoring.MetricSample definition in A.1.3.1, only in the description element say that “A single metric sample,applicatio KPI, like CPU, MEMORY, etc”, but there is no other place in the sample saying what exactly this sample metric monitoring for, cpu or memory? Maybe in the monitoring_endpoint capability, it needs to indicate what parameter does this endpoint expose to the outside for monitoring, so when a sample metric connect to this endpoint, it means that this sample metric is for that paramter.
 
Those are my rough understanding for this proposal.
