Ceilometer - Telemetry asennus

controller.foo.bar

1. Asennetaan mongodb -tietokanta, Telemetry-palvelua varten.

# apt-get install mongodb-server mongodb-clients python-pymongo

2. Muokataan /etc/mongodb.conf -tiedostoa.

bind_ip = 10.0.0.11
smallfiles = true

3. Pysäytetään mongodb, poistetaan mahdolliset tietokannat ja käynnistetään mongodb uudelleen.

# service mongodb stop
# rm /var/lib/mongodb/journal/prealloc.*
# service mongodb start

4. Luodaan ceilometer-tunnus mongodb:lle.

# mongo --host 10.0.0.11 --eval '
  db = db.getSiblingDB("ceilometer");
  db.addUser({user: "ceilometer",
  pwd: "ceilometerdb",
  roles: [ "readWrite", "dbAdmin" ]})'

5. Luodaan ceilometer-käyttäjä, service ja endpoint Keystonelle:

# keystone user-create --name ceilometer --pass ceilometer
+----------+----------------------------------+
| Property |              Value               |
+----------+----------------------------------+
|  email   |                                  |
| enabled  |               True               |
|    id    | 8ba52fed0a9f41a2be0773caf50aa430 |
|   name   |            ceilometer            |
| username |            ceilometer            |
+----------+----------------------------------+

6. Lisätään ceilometer-tunnukselle admin-rooli ja lisätään tunnus service tenant-ryhmään.

# keystone user-role-add --user ceilometer --tenant service --role admin
(Tämä komento ei oikeinkirjoitettuna tulosta mitään)

7. Luodaan ceilometer-service jonka tyypiksi laitetaan metering.

# keystone service-create --name ceilometer --type metering --description "Telemetry"
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
| description |            Telemetry             |
|   enabled   |               True               |
|      id     | 0b4574d6a9ba458e988c4be17c007e46 |
|     name    |            ceilometer            |
|     type    |             metering             |
+-------------+----------------------------------+

8. Luodaan endpoint ceilometerille.

# keystone endpoint-create --service-id $(keystone service-list | awk '/ metering / {print $2}') \
--publicurl http://10.0.0.11:8777 \
--internalurl http://10.0.0.11:8777 \
--adminurl http://10.0.0.11:8777 --region regionOne
+-------------+----------------------------------+
|   Property  |              Value               |
+-------------+----------------------------------+
|   adminurl  |      http://10.0.0.11:8777       |
|      id     | 923731931a204168af09087e87235d3c |
| internalurl |      http://10.0.0.11:8777       |
|  publicurl  |      http://10.0.0.11:8777       |
|    region   |            regionOne             |
|  service_id | 0b4574d6a9ba458e988c4be17c007e46 |
+-------------+----------------------------------+

9. Asennetaan Ceilometer-api ja agentit:

# apt-get install ceilometer-api ceilometer-collector \
ceilometer-agent-central ceilometer-agent-notification \
ceilometer-alarm-evaluator ceilometer-alarm-notifier \
python-ceilometerclient

10. Luodaan satunnaisjono metering_secret -arvolle.

# openssl rand -hex 10
f2181ad45e6afde66f94 

11. Muokataan /etc/ceilometer/ceilometer.conf -tiedostoa.
