-A '''watchdog''' is a mechanism for detecting system states (e.g. full filesystems, database failures, etc.) that require immediate attention by project staff. Typically the desired response to such a condition is to notify a pager, sending a short text description.

 BOINC provides a framework for defining watchdogs:
 
- * A set of '''watchdog scripts''' are run from cron. Each script checks for an error condition, and present, it appends a descriptive line to an error log file. An example is '''wd_nresults_changing.php''', which makes sure that the number of results changes.
- * The script '''wd.php''', also run from cron, scans the error log files. If any has been updated since the last run, it sends email to a set of recipients, containing the last line of the file.
+ * A set of '''watchdog scripts''' are run as periodic tasks. Each script checks for an error condition, and present, it appends a descriptive line to an error log file. An example is '''wd_nresults_changing.php''', which makes sure that the number of results changes.
