OOF is one of the first projects to provide metrics to Prometheus.   

As part of that, OOF integrated Python based exporter client software.

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

# 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.
