Prometheus Plugin Interface
===========================

This interface is used for notifying alert that is detected by
the External Monitoring Tool. The External Monitoring Tool is
Prometheus based Monitoring system.

The Prometheus Plugin has 5 functions:

- Alerting interface for ETSI NFV-SOL 002/003 based Performance Management Job.
- Alerting interface for ETSI NFV-SOL 002/003 based Performance Management
  Threshold.
- Alerting interface for ETSI NFV-SOL 002/003 based Fault Management.
- Alerting interface for Prometheus Plugin AutoScaling.
- Alerting interface for Prometheus Plugin AutoHealing.
