Description RHOS Integration 2014-08-08 04:03:29 UTC 
Cloned from launchpad blueprint https://blueprints.launchpad.net/ceilometer/+spec/predictive-failure-metric.

Description:

We would like to have a metric to monitor and predict host failures. This would require changes to the Ceilometer code:
These are the changes required in Ceilometer files (6 lines total). 

    Add line to ceilometer entry_points.txt file:
            host_pfa = ceilometer.compute.notifications.cpu:HostPfa

     Add line to ./compute/notifications/cpu.py
            class HostPfa(ComputeMetricsNotificationBase):
                 """Handle predictive failure alert message."""
               metric = 'host.pfa'
               sample_type = sample.TYPE_GAUGE
               unit = 'bool'
