8 Monitoring Error handling Create an error handler When you create new error handling rules, you can insert them into existing error handling rule sets or create new rule sets for them. These must be nested themselves in top-level rule sets known as error handlers. This section tells you how to create an error handler. Note: You can also use the Default error handler for inserting new nested error handling rule sets. Complete the following procedure to do this: 1 Go to Policy | Rule Sets. 2 From the Rule Sets menu, select Error Handler. 3 On the error handler tree, go to the position where you want to insert the new error handler. Then click Add. 4 From the drop-down menu that appears, select Error Handler. The Add New Error Handler window opens with the Rule Sets tab selected. 5 Configure the following general settings: • Name — Name of the error handler • Enable — When selected, the error handler is enabled. • [Optional] Comment — Plain-text comment on the log handler. 6 [Optional] Click the Permissions tab and configure who is allowed to access the new error handler. 7 Click OK to close the Add New Error Handler window. The error handler is inserted into the tree structure. 8 Click Save Changes. You can now insert one or more nested rule sets into the error handler and fill these with rules. For more information on creating a rule set, see Add a new rule set and Access restrictions. For the rule sets that are by default available for error handling, see Rule sets for error handling. 314 McAfee Web Gateway 7.1.5 Product Guide
