When a process calls asl_log (or syslog), there's a filter that determines whether the message gets sent to syslogd. That's the filter that you are correctly changing with asl_set_filter. Normally, the filter screens out Info and Debug level messages, If you set it to ASL_FILTER_MASK_UPTO(ASL_LEVEL_DEBUG) or LOG_UPTO(LOG_DEBUG) when using the syslog(3) API, then your process doesn't screen out anything. When a message is received and processed by syslogd, more sorting and filtering takes place. For messages that are saved in the ASL database, there's a filter that's very similar to the client-side filter. By default, it screens out Info and Debug level messages. Messages that get saved to the "Legacy" BSD log files, like /var/log/ system.log, have their own filtering rules that are found in /etc/ syslog.conf. The "syslog" command line utility does a database seacrh, so if you want to use it to retrieve Debug level messages, you'll need to adjust the database filter. You can do that temporarily (until the next time syslogd restarts) with: That sets syslogd's filter to ASL_FILTER_MASK_UPTO(ASL_LEVEL_DEBUG). See the syslog(1) man page for details. You can also set the filter in syslogd's startup plist: /System/Library/LaunchDaemons/ com.apple.syslogd.plist. Add to the ProgramArguments. See the syslogd(8) man page for details. If you change the plist, you'll need to reboot (or stop and re-start syslogd using launchctl) for the change to take effect. I'd like to send debug messages to the asl system log on Leopard without using sudo, but haven't had any success. Here's a small test program that will also send a "test" message with the "raduis" facility: but didn't find anything. I checked to make sure the the master filter was off, and it was. If you read through the man page, you'd also find that the following code *should* work: But due to a bug in asl_open(), it doesn't. Sorry about that! The bug will be fixed in 10.5 (Leopard). That didn't work either. I searched the lists for 'ASL_LEVEL_DEBUG' but didn't come up with anything beyond the two tests above. Any ideas why neither of those two programs work on 10.5.2? Any ideas what would? This email sent to site_archiver@lists.apple.com
