- this change adds rsyslog (https://github.com/rsyslog/rsyslog) as
a new service that runs on every AWX node (managed by supervisord)
in particular, this feature requires a recent version (v8.38+) of
rsyslog that supports the omhttp module
(https://github.com/rsyslog/rsyslog-doc/pull/750)
- the "external_logger" handler in AWX is now a SysLogHandler that ships
logs to the local UDP port where rsyslog is configured to listen (by
default, 51414)
- every time a LOG_AGGREGATOR_* setting is changed, every AWX node
reconfigures and restarts its local instance of rsyslog so that its
fowarding settings match what has been configured in AWX
- unlike the prior implementation, if the external logging aggregator
(splunk/logstash) goes temporarily offline, rsyslog will retain the
messages and ship them when the log aggregator is back online
- 4xx or 5xx level errors are recorded at /var/log/tower/external.err
