| | 3 | 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. |

| | 8 | * 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. |
| | 9 | * 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. |
