Hello TripleOers, I got a patch together to move us off of our upstart exec <service> | logger -t <service> hack [1] and this got me wondering - why aren't we using the python logging.conf supported by most OpenStack projects [2] to write out logs to files in our desired location?
This is highly desirable for a couple reasons: * Less complexity / more straightforward. Basically we wouldn't have to run rsyslog or similar and have app config to talk to syslog then syslog config to put our logs where we want. We also don't have to battle with upstart + rsyslog vs systemd-journald differences and maintain two sets of configuration. * We get actual control over formatting. This is a double edged sword in that AFAICT you *have* to control formatting if you're using a logging.conf with a custom log handler. This means it would be a bit of a divergence from our "use the defaults" policy but there are some logging formats in the OpenStack docs [3] named "normal", maybe this could be acceptable? The big win here is we can avoid issues like having duplicate timestamps [4] (this issue still exists on Ubuntu, at least) without having to do two sets of configuration, one for upstart + rsyslog, one for systemd. * This makes setting custom logging configuration a lot more feasible for operators. As-is, if an operator wants to forward logs to an existing central log server we dont really have a good way for them to do this. We also have a requirement that we can come up with a way to expose the rsyslog/journald config options needed to do this to operators. If we are using logging.conf we can just use our existing passthrough-config system to let operators simply write out custom logging.conf files which are already documented by OpenStack. Thoughts? Comments? Concerns?
