Install and configure controller node
This section describes how to install and configure the Telemetry module, code-named ceilometer, on the controller node. The Telemetry module uses separate agents to collect measurements from each OpenStack service in your environment.
To configure prerequisites
Before you install and configure Telemetry, you must install
MongoDB
, create a MongoDB database, service credentials,
and API endpoint.

Enable the Open Build Service repositories for MongoDB based on your openSUSE or SLES version:
On openSUSE:
# zypper addrepo -f obs://server:database/openSUSE_13.2 Database
On SLES:
# zypper addrepo -f obs://server:database/SLE_12 Database
Note
The packages are signed by GPG key
05905EA8
. You should verify the fingerprint of the imported GPG key before using it.Key Name: server:database OBS Project <server:database@build.opensuse.org> Key Fingerprint: 116EB863 31583E47 E63CDF4D 562111AC 05905EA8 Key Created: Mon 08 Dec 2014 09:54:12 AM UTC Key Expires: Wed 15 Feb 2017 09:54:12 AM UTC

- Edit the
/etc/mongodb.conf
file and complete the following actions:Configure the
bind_ip
key to use the management interface IP address of the controller node.bind_ip = 10.0.0.11
By default, MongoDB creates several 1 GB journal files in the
/var/lib/mongodb/journal
directory. If you want to reduce the size of each journal file to 128 MB and limit total journal space consumption to 512 MB, assert thesmallfiles
key:smallfiles = true
You can also disable journaling. For more information, see the MongoDB manual.
Start the MongoDB services and configure them to start when the system boots:
# systemctl enable mongodb.service # systemctl start mongodb.service

/etc/mongod.conf

If you change the journaling configuration, stop the MongoDB service, remove the initial journal files, and start the service:
# service mongodb stop # rm /var/lib/mongodb/journal/prealloc.* # service mongodb start
You can also disable journaling. For more information, see the MongoDB manual.

with the password you chose for theceilometer
user in the Identity service.Note
Comment out any
