Events and Logs Overview

Use the Events and Logs page to get an overall, high‐level view of your network environment. You can view abnormal events, attacks, viruses, or worms when log data is correlated and analyzed.

This page provides administrators with an advanced filtering mechanism and provides visibility into actual events collected by the Log Collector. Using the time-frame slider, you can instantly focus on areas of unusual activity by dragging the time slider to the area of interest to you. The slider and the Custom button under Time Range remain at the top of each tab. Users select the time range, and then they can decide how to view the data, using the summary view or detail view tabs.

By default, you can view data for all the devices. To view data for a specific device, click on the link beside Devices and select a device.

To access the Event Viewer page select Monitor > Events & Logs > All Events.

Events & Logs—Summary View

Click Summary View for a brief summary of all the events in your network. At the center of the page is critical information, including total number of events, viruses found, total number of interfaces that are down, number of attacks, CPU spikes, and system reboots. This data is refreshed automatically based on the selected time range. At the bottom of the page is a swim-lane view of different events that are happening at a specific time. The events include firewall, Web filtering, VPN, content filtering, antispam, antivirus, IPS, Sky ATP, Screen, and Apptrack. Each event is color‐coded, with darker shades representing a higher level of activity. Each tabs provide deep information like type, and number of events occurring at that specific time.

See Table 6 the descriptions of the widgets in this view.

Advanced Search

You can perform advanced search of all events using the search text box present above the grid. It includes the logical operators as part of the filter string. Enter the search string in the text box and based on your input, a list of items from the filter context menu is displayed. You can select a value from the list and then select a valid operator based on which you want to perform the advanced search operation. Press Spacebar to provide AND operator and OR operator. After you have entered the search string, press Enter to display the search result in the grid.

In the search text box, when you hover over the icon, it displays an example filter condition. When you start entering the search string, the icon indicates whether the filter string is valid or not. While entering a search criteria, when you press backspace at any point of time, only one character is deleted.

Starting in Junos Space Security Director Release 19.2R1, in addition to the manual search using keywords, you can drag and drop the values from non-empty cells in the grid into the event viewer search bar. The value is added as the search criterion and the search results are displayed. You can drag and drop only searchable cells. When you hover over the rows in event viewer, searchable cells are displayed with blue background. If a cell is not searchable, there is no change in the background color. If you drag a searchable cell without any value or if the value = ’–’, you cannot drop the contents of such cells. If the search bar already has a search criterion, all the subsequent drag and drop search criteria are prepended by ‘AND’. After dropping the value in the search bar, the search condition is refreshed in the grid. This applies to both simple and complex search filters.

You can perform complex filtering using AND and OR logical operators, and brackets to group the search tokens.

For example: (Name = one and id = 11) or (Name = two and id = 12)

The precedence level of the AND logical operator is higher than OR. In the following filter query, Condition2 AND Condition3 is evaluated before the OR operator.

For example: Condition1 OR Condition2 AND Condition3

To override this, use parentheses explicitly. In the below filter query, expression inside the parentheses is evaluated first.

For example: ( Condition1 OR Condition2 ) AND Condition3

Table 8: Filter Rules

 

Filter Rule

Example

Enter a comma for an OR filter.

Name=test,site is the same as Name=test OR Name=site

Enter parentheses to combine AND and OR functionality.

Source Country = France AND (Event Name = RT_Flowsession_Close OR Event Category = Firewall)

Enter double quotes for terms with spaces.

"San Jose"

Following are some of the examples for event log filters:
