Ceilometer Configuration Options

Ceilometer Sample Configuration File

Configure Ceilometer by editing /etc/ceilometer/ceilometer.conf.

No config file is provided with the source code, it will be created during the installation. In case where no configuration file was installed, one can be easily created by running:

oslo-config-generator \
    --config-file=/etc/ceilometer/ceilometer-config-generator.conf \
    --output-file=/etc/ceilometer/ceilometer.conf

The following is a sample Ceilometer configuration for adaptation and use. It is auto-generated from Ceilometer when this documentation is built, and can also be viewed in file form.
