The correct way to do this is to use the new watchdog hook that made it
to Drupal 6.
Here is the API call
http://api.drupal.org/?q=api/function/hook_watchdog/HEAD
There are already standards in place for alert levels that the above hook
and modules that call it can use.
There is a backport of that to Drupal 5.x here
http://drupal.org/node/149341
The syslog module in the above patch, and in D6 can already log to
a flat file, and the output is themable so you can format it however
you like.
Here is an example module that does logging to email per severity level.
http://drupal.org/project/logging_alerts
And again...
The company I work for bases all of our projects on the Drupal
infratructure. The watchdog application simply doesn't work for us, so
I'd created a module to log messages to file in the format:
00:00:58 [module::function_name][LOG_LEVEL]: Checking to see if user
0c2f977cc24e4e41d8cd6d9a4099ab0b is anonymous.
We've decided that this is likely a worthwhile project to release to the
community, so I am currently working on a release. Right now, I have a
group of Log Levels (FATAL, ERROR, WARN, INFO, DEBUG, TRACE), one log
type (DRUPAL_BASE) and the ability to add/configure more.
The site admin can configure whether or not to turn on logging, a
minimum log level to write out, where the log files should live, etc.
I will send another message once the initial release is made, but wanted
to gauge what people thought about this module. It's more of a
developer's module, as it requires developers to add a hook, such as:
drupal_log_to_file("MODULE_NAME::FUNCTION_NAME", "LOG_TYPE",
LOG_LEVEL, "MESSAGE")
into their code, in order for the system to log anything.
Let me know anyone's thoughts :)
