Under the configure option in the top menu navigation, select Filters. From here you can chose to edit or delete an existing filter under the Actions column or click the Add New Response Filter. Adding or editing a response filter displays the following fields:
Name: Be sure to specify a descriptive filter name so that you can identify the filter later in a dropdown list of other filters.
Description: Add additional explanations for what this filter is intended to accomplish.
Ignore an Error if the following error conditions apply: You can specify multiple filters to help eliminate false positives and excessive alerts.
Error is reported for less than x minutes: errors will be suppressed until the number of minutes specified have passed between failing errors.
Error is not confirmed by at least x monitoring locations: Errors will be suppressed until the error has been confirmed by x number of locations.
Error is detected in less than x tasks: The error will be supressed until x number of tasks have confirmed the error. (These must be tasks included within the same device. Tasks from multiple devices will not be considered valid in this filter.)
Error if Owner Device is Down: If you have selected an Owner Device for a particular device, errors for the device this filter is applied to will be suppressed if the owner device is currently returning errors or is unavailable.
You can also specify a filter to ignore specific error types.
