Monitor Web Filtering Events


You are here: Monitor > Events > Web Filtering.

Use this page to view information about the web filtering events based on web filtering policies, widget details, filter options, and grid elements of Web filtering events.

Using the time-range slider, you can quickly focus on the time and area of activity that you are most interested in. Once the time range is selected, all of the data presented in your view is refreshed automatically. You can also use the Custom button to set a custom time range.

You can select either the Grid View tab or the Chart View tab to view your data:

  • Grid View—View the comprehensive details of web filtering events in a tabular format that includes sortable columns. You can group the events using the Group By option. For example, you can group the events based on source country. The table includes information such as the event name, time, source IP, source country, and so on. Table 1 describes the fields on the Grid View page.

  • Chart View—View a brief summary of all the web filtering events in your network. The top of the page has a swim lane graph of all the screen events. You can use the widgets at the bottom of the page to view critical information such as, top sources, Top URLs blocked, and Top URL Categories Blocked. Table 2 describes the widgets on the Chart View page.

The filter list that is displayed above the grids.

Options available in the filter list are:

  • Event Name—Displays the event name of the log.

  • Source Address—Displays the source addresses to be used as match criteria for the policy. Address sets are resolved to their individual names.

  • Destination Address—Displays the destination addresses (or address sets) to be used as match criteria for the policy. Addresses are entered as specified in the destination zone’s address book.

  • Source Name—Displays the source name of the log.

  • User—Displays the user name from whom the log is generated.

  • Role—Displays the role names associated with the event.

  • Reason—Displays the reason for the log generation. For example, a connection tear down may have an associated reason such as authentication failed.

  • Profile—Displays the profile name in the log.

  • Protocol—Displays the protocol in the log.

  • Category—Displays the category of the log.

Select the criteria or parameter on which you want to construct the filter statement.

Text box

Displays the filter parameter that you selected from the filter list.

Note: In the filter statement the following limitation exists.

  • You can use only one operator at a time.

  • You can use only one instance of the criteria or parameter in one filter statement.

For example, if you have used & operator and the parameter Event-Name once, I cannot use them again in the same filter statement

CORRECT USAGE: Event-Name = rt_flow_session_close & application=TELNET

WRONG USAGE: Event-Name = rt_flow_session_close & Event-Name = rt_flow_session_create

WRONG USAGE: Event-Name = rt_flow_session_close & source-address = x.x.x.x & application = TELNET

Note: The filter statement is NOT case-sensitive.

Add the parameter for which you want to filter. For example, in the filter list if you selected event-name as the parameter, the text box displays Event-Name=. If you add WEBFILTER_URL_BLOCKED to see only Web filtering events then the text box displays Event-Name = WEBFILTER_URL_BLOCKED.
