Improve documentation on Ceilosca not needing Gnocchi
There was a recent question in IRC about how to configure Ceilosca. These edits should make it clearer that Gnocchi is not needed in a Ceilosca deployment, and how to disable it. Change-Id: I25b894e1ad222e3b55c6787c0625c03b9ebdcbf1

Python plugin and storage driver for Ceilometer to send samples to monasca-api. Also known as Ceilosca.
To set up Ceilosca automatically, read the instructions in devstack/README.md or use the included Vagrantfile
Assumes that an active monasca-api server is running after installing DevStack.
Not all Ceilometer components are required. The following may be disabled in
local.confif using an older Ceilometer release. :
disable_service ceilometer-alarm-notifier disable_service ceilometer-alarm-evaluator disable_service ceilometer-collector
- Panko and Aodh from the Telemetry project are not required, as Monasca will be providing these types of services.
Gnocchi is also not required, as Monasca uses a configured Time-Series Database for measurement storage.
Gnocchi installation in DevStack may be skipped by setting the following in
pip install python-monascaclient
Copy the following files from
ceilosca/ceilometer to devstack’s ceilometer location, typically at
monasca_client.py monasca_opts.py opts.py publisher/monasca_data_filter.py publisher/monasca.py tests/* (skipping the init.py files)
setup.cfg (used at the time of installation)
Under ‘ceilometer.sample.publisher =’ section add the following line:
monasca = ceilometer.publisher.monasca:MonascaPublisher
/etc/ceilometer/pipeline.yamlto send the metrics to the monasca publisher. Use the included
monasca-ceilometer/etc/ceilometer/pipeline.yamlfile as an example.
/etc/ceilometer/ceilometer.conffor setting up storage driver for Ceilometer. Use the included
monasca-ceilometer/etc/ceilometer/ceilometer.conffile as an example.
Copy the included
monasca_field_definitions.yml file from
monasca_field_definitions.yaml file contains configuration how to treat each field in Ceilometer sample object on per meter basis. The
monasca_data_filter.py uses this file and only stores the fields that are specified in this config file.
ceilometer.confhas monasca_user role added.
Since we don’t have a full repo of ceilometer, we setup the ceilometer repo in venv and copy monasca integration files in there, and run the unit tests over that code. At present this is tested against ceilometer stable/pike branch, if you need to test against different branch you can change it in test-requirements.txt

From time to time, Ceilometer introduces new meters. The list of currently supported measurements can be found at https://docs.openstack.org/ceilometer/pike/admin/telemetry-measurements.html (which is generated from https://github.com/openstack/ceilometer/doc/source/admin/telemetry-measurements.rst).
Some meters require additional configuration in Ceilometer. For example, the SDN pollster meters need specialized drivers. For more information about how Ceilometer collects meters through polling or collecting, please reference the Telemetry documentation and measurements.
As with Ceilometer, the list of meters to be published is specified in
As metering data accumulates over time, it is recommended that Ceilometer be configured to only publish meters where the customer has a need for the data. Additionally, it is recommended to check the measurements captured by Monasca agents to avoid any duplication of data.
To enable or disable meters,
/etc/ceilometer/pipeline.yaml. Hint: You can see which meters are currently being reported through
ceilometer meter-listin Pike and earlier).
/etc/ceilometer/pipeline.yamlfile to add or remove entries from the meters list.
To create new meters (or clean out removed meters),
monasca_field_definitions.ymlwith the new meters.
Also note that HPE published documentation describing how to configure the metering service (using Ceilosca in Helion OpenStack 3.0 and later), which may be helpful for historical context. link 1 link 2 link 3
Here are a few examples of how a meter gathered by Ceilometer and passed through Ceilosca can be found and used in the Monasca API.
In Ceilometer pipeline YAML file
|Ceilometer meter||Monasca API metric|
Note: Monasca Agent can gather many similar metrics directly, such as cpu time for a VM. For simplicity, it is recommended that the Monasca Agent be favored when choosing which metrics to use.
