Typically one may specify a logging-level (verbose, warning, error) with each log message. The user then can specify run time log level at which point all messages at a level >= log-level get displayed (error would be the highest level and always display). New to Open Stack .. my vote .. go ahead an add the log messages, bet I will benefit from them! The only time logging can interfere is when there are race condition bugs that one is trying to debug .. the issue then is the process of inspection alters the inspected!

Would it be useful to contribute such small logging-only patches aplenty as they appear or would that just unnecessarily bother the reviewers? Are there any logging "best practices" in OpenStack - e.g., is anyone worried about the possible code bloat or "log bloat" due to too many logging statements? (my experience says that it's impossible to have too many logging statements in a complex system, but well). Also, is the log format supposed to be machine-parseable / do people depend on it, or does it make sense to try introducing patches increasing readability of logs, fixing typos etc.? Thanks. [That's my first email to the list. Nice to meet you. I'm a huge fan of everything that helps understand the behavior of distributed systems, thus my interest specifically in logging] -- Eugene Kirpichov http://www.linkedin.com/in/eugenekirpichov _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp _______________________________________________ Mailing list: https://launchpad.net/~openstack Post to : [email protected] Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
