Magento - how to write in the admin actions log?

As per title. Can't seem to find anything rel开发者_如何转开发evant.

app/code/core/Enterprise/Logging is what I think your looking for.

This is from the Model/Handler/Controllers.php file.

    //Add log entry details
    if ($data) {
        $change = Mage::getModel('enterprise_logging/event_changes');
        $processor->addEventChanges($change->setSourceName('params')
            ->setOriginalData(array())
            ->setResultData($data));
    }

I've never used it but hope it helps?
