The Telemetry service has similar log settings as the other OpenStack services. Multiple options are available to change the target of logging, the format of the log entries and the log levels.
The log settings can be changed in
ceilometer.conf. The list of
configuration options are listed in the logging configuration options
table in the Telemetry
in the OpenStack Configuration Reference.
stderr is used as standard output for the log messages.
It can be changed to either a log file or syslog. The
verbose options are also set to false in the default settings, the
default log levels of the corresponding modules can be found in the
table referred above.
