HPA matching logic is the first one in OOF to export its metrics.

Scope of R3 is to integrate OOF and Prometheus with basic hpa/vnf statistics with minimum labels. R4 will integrate more detailed metrics with additional label support.

OOF-HPA metrics (Dileep Ranganathan)

...

• Number of times there is successful flavor match :   flavor_match_successful
• Number of times there is unsuccessful flavor match:  flavor_match_unsuccessful
• Number of times cloud region is selected successfully :  cloud_region_successful_selection
• Number of times no cloud region is selected:  cloud_region_unsuccessful_selection

Metrics alone does not provide much information. Labels for each metric quality the metric.

...

Labels for cloud_region_successful_selection and cloud_region_unsuccessful_selection (R4)

• cloud_region
• service_name
• customer_name

In case of cloud_region_unsuccessful_selection, few more additional labels would help (R4)

• no_selection_due_to_flavors
• no_selection_due_to_distance
• no_selection_due_to_cost

Current Metrics planned to support in R3

# General rule of thumb - if label not available. Label=N/A
# Service name will be set as N/A for HPA metrics in R3.

# Currently this needs lots of changes. R4 will take care of this.
