Follow Gnocchi installation instructions
Initialize Gnocchi for Ceilometer:
$ gnocchi-upgrade --create-legacy-resource-types
Note
Prior to Gnocchi 2.1, Ceilometer resource types were included, therefore –create-legacy-resource-types flag is not needed.
Edit /etc/ceilometer/ceilometer.conf for the collector service:
[DEFAULT]
meter_dispatchers = gnocchi
event_dispatchers = gnocchi
[dispatcher_gnocchi]
filter_service_activity = False # Enable if using swift backend
filter_project = <project name associated with gnocchi user> # if using swift backend
[service_credentials]
auth_url = <auth_url>:5000
region_name = RegionOne
password = password
username = ceilometer
project_name = service
project_domain_id = default
user_domain_id = default
auth_type = password
Copy gnocchi_resources.yaml to config directory (e.g./etc/ceilometer)
To minimize data requests, caching and batch processing should be enabled:
Enable resource caching (oslo.cache should be installed):
[cache]
backend_argument = redis_expiration_time:600
backend_argument = db:0
backend_argument = distributed_lock:True
backend_argument = url:redis://localhost:6379
backend = dogpile.cache.redis
Enable batch processing:
[notification]
batch_size = 100
batch_timeout = 5
Start notification service
Clone the ceilometer git repository to the management server:
$ cd /opt/stack
$ git clone https://git.openstack.org/openstack/ceilometer.git
As a user with root permissions or sudo privileges, run the ceilometer installer:
$ cd ceilometer
$ sudo python setup.py install
Generate configuration file:
$ tox -egenconfig
Copy the sample configuration files from the source tree to their final location:
$ mkdir -p /etc/ceilometer
$ cp etc/ceilometer/*.yaml /etc/ceilometer
$ cp etc/ceilometer/ceilometer.conf /etc/ceilometer
Edit /etc/ceilometer/ceilometer.conf
Configure messaging:
[oslo_messaging_notifications]
topics = notifications
[oslo_messaging_rabbit]
rabbit_userid = stackrabbit
rabbit_password = openstack1
rabbit_hosts = 10.0.2.15
Set the telemetry_secret value.
Set the telemetry_secret value to a large, random, value. Use the same value in all ceilometer configuration files, on all nodes, so that messages passing between the nodes can be validated. This value can be left empty to disable message signing.
Note
Disabling signing will improve message handling performance
Refer to Configuration Options for details about any other options you might want to modify before starting the service.
Edit /etc/ceilometer/ceilometer.conf:
Change publisher endpoints to expected targets. By default, it pushes to a metering.sample topic on the oslo.messaging queue. Available publishers are listed in Publishers section.
Start the notification daemon:
$ ceilometer-agent-notification
Note
The default development configuration of the notification logs to stderr, so you may want to run this step using a screen session or other tool for maintaining a long-running program in the background.
Note
The polling agent needs to be able to talk to Keystone and any of the services being polled for updates. It also needs to run on your compute nodes to poll instances.
Clone the ceilometer git repository to the server:
$ cd /opt/stack
$ git clone https://git.openstack.org/openstack/ceilometer.git
As a user with root permissions or sudo privileges, run the ceilometer installer:
$ cd ceilometer
$ sudo python setup.py install
Generate configuration file:
$ tox -egenconfig
Copy the sample configuration files from the source tree to their final location:
$ mkdir -p /etc/ceilometer
$ cp etc/ceilometer/*.yaml /etc/ceilometer
$ cp etc/ceilometer/ceilometer.conf /etc/ceilometer/ceilometer.conf
Configure messaging by editing /etc/ceilometer/ceilometer.conf:
[oslo_messaging_rabbit]
rabbit_userid = stackrabbit
rabbit_password = openstack1
rabbit_hosts = 10.0.2.15
In order to retrieve object store statistics, ceilometer needs access to swift with ResellerAdmin role. You should give this role to your os_username user for tenant os_tenant_name:
$ openstack role create ResellerAdmin
+-----------+----------------------------------+
| Field | Value |
+-----------+----------------------------------+
| domain_id | None |
| id | f5153dae801244e8bb4948f0a6fb73b7 |
| name | ResellerAdmin |
+-----------+----------------------------------+
$ openstack role add f5153dae801244e8bb4948f0a6fb73b7 \
--project $SERVICE_TENANT \
--user $CEILOMETER_USER
Start the agent:
$ ceilometer-polling
By default, the polling agent polls the compute and central namespaces. You can specify which namespace to poll in the ceilometer.conf configuration file or on the command line:
$ ceilometer-polling --polling-namespaces central,ipmi
Note
The Ceilometer’s API service is no longer supported. Data storage should be handled by a separate service such as Gnocchi.
Edit nova.conf to include:
[DEFAULT]
instance_usage_audit=True
instance_usage_audit_period=hour
notify_on_state_change=vm_and_task_state
[oslo_messaging_notifications]
driver=messagingv2
Configure the driver in sahara.conf:
[DEFAULT]
enable_notifications=true
[oslo_messaging_notifications]
driver=messagingv2
Edit proxy-server.conf to include:
[filter:ceilometer]
topic = notifications
driver = messaging
url = rabbit://stackrabbit:openstack1@10.0.2.15:5672/
control_exchange = swift
paste.filter_factory = ceilometermiddleware.swift:filter_factory
set log_level = WARN
and edit [pipeline:main] to include the ceilometer middleware before the application:
[pipeline:main]
pipeline = catch_errors ... ... ceilometer proxy-server
Also, you need to configure messaging related options correctly as written above for other parts of installation guide. Refer to Configuration Options for details about any other options you might want to modify before starting the service.
