Searching Events

Role Availability Read-Only Analyst Manager

USM Anywhere includes several filters displayed by default. These filters enable you to search for your items of interest. You can either filter your search, or enter what you are looking for in the search box, which is in the upper left corner of the page.

You can configure more filters and change which filters are displayed by clicking the Configure filters link, which is located in the upper left corner of the page.

Note: The management of filters is similar to that for assets. See Managing Filters for more information.

The number between brackets displayed by each filter indicates the number of items that matches the filter. You can also use the filter controls to provide a method of organizing your search and filtered results. These are the icons next to each filter title:

Sort the filters by number of items that matches them.

In the upper left side of the page, you can see any filters you have applied. Remove filters by clicking the icon next to the filter. Or clear all filters by clicking Reset All Filters.

Note: When applying filters, the search uses the logical AND operator if the used filters are different. However, when the filter is of the same type, the search uses the logical OR.

Those filters that have more than ten options include a Filter Value search box for writing text and make the search easier.

About the "Was Fuzzied" Filter

When USM Anywhere receives raw log data on the USM Anywhere Sensor, it tries to match them with plugins based on hints and manual associations. Sometimes that process fails and events are processed by the AlienVault Generic Plugin, which attempts to find some common information using "fuzzy" matching.  These events can be found by filtering by the data source plugin or the "Was Fuzzied" fields.

Important: An event having the "Was Fuzzied" field with the value "true" has its data source property as "[empty]".

See The AlienVault Generic Plugin for more information about how this plugin attempts to normalize an unmatched log message.
