[Mono-list] Diagnostic Messages

[Jonathan Pryor]

If `syslog' were to be used, what would you suggest for the facility? 
`LOG_USER' might make sense, using `LOG_DEBUG' for Debug-generated
messages and `LOG_WARNING' or `LOG_INFO' for Trace-generated messages.

The one downside with using `syslog' is that you wouldn't see the
messages from inside GDB when debugging under GDB.  You would instead
need to have a different terminal open to view the contents of the
system logfile.  (At least, the only way I currently know to view the
output of `syslog' is to `tail -f /var/log/message' as root, which is
undesirable for multi-user installations.)

So I'm not sure if `syslog' is a better solution.  However, I don't know
much about `syslog' either, so I'm interested in hearing more.  However,
it seems that `System.Diagnostics.EventLog' and related classes would
probably be a closer fit to `syslog' than the `Trace' and `Debug'
classes.

Thanks,

    BSDs (and perhaps Linux, I don't know) have the syslog facility, that is 
    probably the most appropriate equivalent.
