• Run a search on any of the following fields:
  • DEVICE NAME
    
  • DHCP FINGERPRINT
    
  • DNS VIEW
  • MAC ADDRESS
    
  • OS VERSION
    
  • QUERY
  • QUERY TYPE
  • RESPONSE
    
  • SOURCE
    
  • USER

• The = and the NOT (!=) operators
• Use the AND and the OR operators.
• Use single and double quoted to enter values with spaces. 
• Use parentheses to group search parts.
• Use the wildcard symbol (*) as the last character of the search value for a partial match.
• Use the ENTER key to apply search.
• Use the TAB key to autocomplete search with the first available suggestion.
• Source

Sample Search Queries

The following are search query examples:

• query=domain.*AND device=52.123*
• device = office1.domain OR device=office2.domain.com
• dns_view=example-view AND query_type=A

• (source=‘Infoblox Endpoint’ OR source=“example 1”) AND device=52.123*

  Search by the query fields matches values by subdomains. E.g. query = domain.com
  matches
  'domain.com', 'office.domain.com', 'space.office.domain.com

Filtering the Users Tab

To filter User events by specific criteria, select the applicable objects from the following drop-down menus located below the top action menu:

• Source: The location of the device within the network infrastructure. For example, the device can be an on-prem appliance or an endpoint device. You can select which records to view by selecting or deselecting from among the options available. When filtering by source, the filter drop-down is limited to showing 10 sources.

• Show: Security and activity events can be filtered by choosing an option from the Show drop-down menu. 

  Note

  Depending on the availability of data records, not all filter options may be displayed.

The Users table displays the following information by specific criteria, where you can select the applicable objects from the following column drop-down menus: 

• REQUESTS: The request type. Clicking the number of requests in the REQUESTS column associated with a user allows you to pivot off the record and display all DNS events associated with the user. 
• DEVICES: The number of devices that are used to access the corresponding DNS content. Clicking the number of requests in the DEVICES column associated with a user allows you to pivot off the record and display all DNS events associated with the user.
