Re: Errorlog empty

The logging_collector is on, but I don’t know if it was restarted after it was turned on. I did run a ‘pg_ctl reload’, but still it did not log any msgs.
Does it need an actual restart? I cannot simply do that because this is production, has to be scheduled.

Thanks.

Maria

My configuration:

log_destination = 'stderr'
logging_collector = on --necesita restart
log_min_duration_statement = 0
log_line_prefix = '%t [%p]: [%l-1] [%r]: user=%u '
log_checkpoints = on
log_connections = on
log_disconnections = on
log_lock_waits = on
log_temp_files = 0

Hi,
In postgresql.conf file you will find some ERROR REPORTING AND LOGGING parameters.
These parameters are responsible for error log generation:

log_destination = 'stderr'
logging_collector = on
log_directory = 'pg_log'

Under When to log:

log_min_error_statement = error
log_min_duration_statement = 0

Under What to log:
log_line_prefix = '%t [%p]: [%l-1] [%r]: user=%u '
log_checkpoints = on
log_connections = on
log_disconnections = on
log_lock_waits = on
log_temp_files = 0

I think changing these parameters will start the error logs in the pg_log folder of your data directory.
