Measurements
==============
A list of the current usage data that ceilometer will (eventually) listen for
can be found at:
Three type of meters are defined in ceilometer:
http://wiki.openstack.org/SystemUsageData.
.. index::
double: meter; cumulative
double: meter; gauge
double: meter; delta
For a list of the planned meters, refer to:
========== ==============================================================================
Type Definition
========== ==============================================================================
Cumulative Increasing over time (instance hours)
Gauge Discrete items (floating IPs, image uploads) and fluctuating values (disk I/O)
Delta Changing over time (bandwidth)
========== ==============================================================================
Here are the counter types by components that are currently implemented:
