You can exclude specific events from being raised as alerts if you find them unnecessary or distracting. To filter the alerts you do not want to receive, you use Exclude Text to indicate the content that identifies an unwanted alert. Use Exclude Text in conjunction with Include Text to refine a subset of an alert category.
There are two methods for filtering alerts from being reported by the monitoring feature. One entails working in the Profile Details page and the other entails using the Choose Action drop-down menu from the Monitoring Alerts list page.
You can filter the alerts you receive based on the message text and severity level.
Use Exclude Text in conjunction with Include Text to refine a subset of an alert category.
NOTE: The criteria match text, for example, error, is matched in Windows event logs against both the severity level and the message itself. |

NOTE: the search would look for matches for code 5code 7. In this case you should use Add to create a separate line for the second inclusion.
NOTE: However, Exclude Text does recognize line breaks within the text box. This means that if you entered
NOTE: the search would look for matches for code 5 together with code 7. In this case you do not need to use Add to create a separate line for the second exclusion. |
Example B: Basic regular expression as exclude text
When you type characters into the exclude or include criteria text fields you can also enter special characters such as single or double quotes. However, if you use these special characters, they must be escaped with a backslash character (\) in order for the search to work properly.
For example, to search for Received 'redoubt started' message, you would type Received \'redoubt started\' message.
