Log Guidelines
Levels Guidelines
During Kilo release cycle 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, cluster start, successful job
execution).
- Warning: Indicates that there might be a systemic issue;
potential predictive failure notice (e.g. job execution failed).
- Error: An error has occurred and an administrator should research the event
(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 functionality; immediately get
administrator assistance (e.g. failed to access keystone/database, plugin
load failed).
Translation Guidelines
All log levels except Debug requires translation. None of the separate cli tools packaged
with Sahara contain log translations.
