Event Log Logging

When specifying the /le option, CheckURL will log all actions to the event log with the event source NTToolkit and the event category CheckURL. Depending on the options specified in the /evt parameter, CheckURL will either log an informational, warning or error event to the event log.

Event Log Rules (/evt)

The event log rules allow you to specify with which severity certain checks will be logged to the event log. For example, you can log an ERROR to the event log if a particular text is not found in an URL, or a WARNING when the checksum of a page has changed.

You can create the event log rules with the following pattern pair: ACTION=SEVERITY,ACTION=SEVERITY,...

Actions

The following actions are available:

•	CHECKSUM_CHANGE A checksum change has been detected

•	CHECKSUM_EQUAL A checksum has not changed

•	TXT_FOUND The specified text has been found in the page

•	TXT_NOTFOUND The specified text has not been found in the page

Severities

Events can be logged with the following severities:

•	Error Logs event as an error

•	Warning Logs event as a warning

•	Information Logs event as a warning

•	Ignore Does not log an event to the event log

Some examples for rules are:

•	TXT_FOUND=Ignore,TXT_NOTFOUND=Warning

•	CHECKSUM_CHANGE=Error,CHECKSUM_EQUAL=Information

Events

CheckURL logs the following events to the event log:

Event ID	Event Message
1000	Unable to connect to "%1" due to error "%2" (%3).
1001	The checksum of URL "%1" was initialized to "%2".
1002	The checksum of URL "%1" changed to "%2".
1003	The checksum of URL "%1" did not change.
