Activiy Log Watcher - seeking advice for how to use this
Using Jamroom
I think the module was created to allow developers greatest space of movement in that 'How' its supposed to be used is left to them.
Think the premise is: The activity log exist, it contains stuff, if you want to do stuff when stuff is put there, use this module.
There already exists a feature to log "Page Not Found" to the activity log, its at
MODULES -> CORE -> SYSTEM CORE -> ACTIVITY LOG -> log 404 Not Found
Turn that on and you'll see any URL that a customer lands on that results in a Not Found error.
Be aware that bots scan sites so you'll probably see a lot of:
your-site.com/xml_rpc.php
type urls and others that just dont make sense like
This is bots guessing that your site might be 'Wordpress' or 'Drupal' and if it is, then they will try to run through a list of known attacks for those systems.
The way a developer might use it could be to add a log to the activity log:
jrCore_logger('MAJ', 'Something happened that I want to know about');
Then use the module to watch for that and notify the developer when it does.
