+===========================
+More Power and Thermal Data
+===========================
+
+https://blueprints.launchpad.net/ceilometer/+spec/power-thermal-data
+
+Add more power and thermal data besides IPMI sensor data and Node Manager basic
+data. These data from platform hardware are independent of OS/driver, and
+valuable to show running status of node.
+
+
+Problem description
+===================
+
+We already have IPMI sensor data and Node Manager basic data, but they don't
+provide enough info of overall picture for server in data center. Some extra
+data can be added, like CUPS(Compute Usage Per Second), which indicates
+CPU/IO/Memory utilization, and Volumetric Airflow, which indicates current
+amount of air that goes through server. These data plus previous basic
+power/thermal data, can be used as input for Nova scheduling.
+
+
+Proposed change
+===============
+
+Add capability to get new data in NodeManager class. Add new pollsters to get
+CUPS and airflow data.
+
+Add following new metrics:

+
+Work Items
+----------
+
+* Add raw IPMI command to get new data in NodeManager class
+
+* Implement 2 new pollster: CUPS and airflow
+
+* Add unit test coverage
+
+* Update related docs
+
+
+Future lifecycle
+================
+
+Once this feature enabled, need test and bug fixing in next 2 releases to avoid
+regression
+
+
+Dependencies
+============
+
+This feature depends on IPMI/NM capable servers
+
+
+Testing
+=======
+
+This feature with previous IPMI sensor data and NM basic data need 3rd party
+testing system to verify its function. This testing system development is in
+progress.
+
+
+Documentation Impact
+====================
+
+The added metrics will need to be documented in the `measurements section`_.
