\JLog

Joomla! Log Class

This class hooks into the global log configuration settings to allow for user configured
logging events to be sent to where the user wishes them to be sent. On high load sites
Syslog is probably the best (pure PHP function), then the text file based loggers (CSV, W3c
or plain Formattedtext) and finally MySQL offers the most features (e.g. rapid searching)
but will incur a performance hit due to INSERT being issued.
