Open Stack

Another approach could be to use Monasca as the back end. The publisher 
has been recently added upstream [1].

It uses InfluxDB as the time series DB. The message queue between the 
API and TSDB adds resiliency and allows setting up InfluxDB in HA.

What you get on top is a generic, multi-tenant monitoring solution. 
Cloud users can install their own agents, push own application metrics 
and set up own alerting per project. Support for auto-scaling with Heat 
templates is included.

Greetings
