Monitoring IPS Events


Use the IPS Events page to view information about security events based on IPS policies and criticality of the IDP events. Analyzing IPS logs yields useful security management information, such as abnormal events or attacks.


To monitor events select Monitor>Events>IPS in the J-Web user interface.


Time Range graph displays the trend of all events or flow for all the events that has transpired in the device.

You can specify the duration of time for which you want to view the trend for all events. The available options are 30m, 1h, 2h,…, and so on, which are displayed at the top right hand side of the page. For example, if you choose 30m, the end time is the current system time and the start time is the preceding 30 minutes from the current system time.

Click Custom to specify a customized time range. The Custom Time Range Selection popup window is presented. You can set the from and to date and time, and click OK to set the time range.

To refresh the graph on demand, click the refresh button.

You can also drag the slider in the Time Range graph from the extreme left or right of the graph and set the time range to see the trend or flow of events that has transpired in that time range.

There are two ways to view your data. You can select either the Summary View tab or the Detailed View tab.

The Summary View is selected by default, and it gives a brief summary of all the IPS events in your network.

The data presented in the line graph (also known as swim lanes) is refreshed automatically based on the selected time range. The line graph shows dark red, red, and yellow lanes that represent critical, high, and medium IDP events based on the criticality of events.

Below the swim lanes are widgets displaying critical information such as top five sources, top five destinations, top IPS attacks, and top IPS severities.

See Table 29 for descriptions of the widgets.

Table 29: Widgets in Summary View

Widget Name


Top Sources

Top five source IP addresses of the network traffic; sorted by event count.

Top Destinations

Top five destination IP addresses of the network traffic; sorted by event count.

Top IPS Attacks

Top five IPS attacks; sorted by event count.

IPS Severities

Donught chart which shows the percentage of IPS events based on their severity levels. The colors are blue, black, green, and amber representing high, info, critical, and medium IPS events respectively.

Click the Detailed View for comprehensive details of events in a grid format that includes sortable columns. It displays information in grids that are lazy loaded with infinite scrolling. You can narrow down your search to a particular event based on IP address or attack name. The table includes information such as the rule that caused the event, severity for the event, event ID, traffic information, and how and when the event was detected.

Table 30: Filter Options in Detailed View

The dropdown filter that is displayed above the grids.

Options available in the filter dropdown are: Event-Name, Source-Address, Destination-Address, Application, User, Service, Policy, Nested-Application, Source-Interface, and Source-Zone.

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 dropdown.


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 paramenter 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 dropdown filter if you selected event-name as the parameter, the text box displays Event-Name =. If you add IDP_ATTACK_LOG_EVENT to see only IPS events then the text box displays Event-Name = IDP_ATTACK_LOG_EVENT.


Executes the filter statement that is displayed in the text box.

Click Go.


Clears the filters.

Click x.
