I've noticed that log messages are only logged with the request if logging() is not used more than twice. Otherwise I have to select 'Info' in the filter. I've set logservice.AUTOFLUSH_ENABLED to False already.
This is a request with 4 log messages and no filter in the logs (dashboard). 2011-09-12 12:01:44.161 / 200 102833ms 42161cpu_ms 28861api_cpu_ms 0kb instance=0 The same request with filter set to 'Info'. 2011-09-12 12:01:44.139 / flush start=2011-09-12,12:00:01.327 instance=0 I 2011-09-12 12:00:35.855 ParameterOutOfRange: 100 I 2011-09-12 12:00:37.555 ParameterOutOfRange: 100 I 2011-09-12 12:01:44.138 200 And a request with only 1 log message, and no filter in the logs.
