Log Guidelines
Levels Guidelines
During the Kilo release cycle the sahara community defined the following log levels:
- Debug: Shows everything and is likely not suitable for normal production operation due to the sheer size of logs generated (e.g. scripts executions, process execution, etc.).
- Info: Usually indicates successful service start/stop, versions and such non-error related data. This should include largely positive units of work that are accomplished (e.g. service setup and configuration, cluster start, job execution information).
- Warning: Indicates that there might be a systemic issue; potential predictive failure notice (e.g. job execution failed).
- Error: An error has occurred and the administrator should research the error information (e.g. cluster failed to start, plugin violations of operation).
- Critical: An error has occurred and the system might be unstable, anything that eliminates part of sahara's intended functionalities; immediately get administrator assistance (e.g. failed to access keystone/database, failed to load plugin).
Formatting Guidelines
Now sahara uses string formatting defined in PEP 3101 for logs.
LOG.warning(_LW("Incorrect path: {path}").format(path=path))Translation Guidelines
All log levels except Debug requires translation. None of the separate cli tools packaged with sahara contain log translations.
- Debug: no translation
- Info: _LI
- Warning: _LW
- Error: _LE
- Critical: _LC
