Using the Context Explorer

Understanding the Context Explorer

Chapter 3

To refresh the Context Explorer:

: Admin/Any Security Analyst



On the Context Explorer, click Reload at the upper right.
The explorer updates to display the latest information within your selected 

time range. Note that the Reload button is grayed out until your refresh is 

finished.

Setting the Context Explorer Time Range

: FireSIGHT

You can configure the Context Explorer time range to reflect a period as short as 

the last hour (the default) or as long as the last year. Note that when you change 

the time range, the Context Explorer does not automatically update to reflect the 

change. To apply the new time range, you must manually refresh the explorer.
Changes to the time range persist even if you navigate away from the Context 

Explorer or end your login session.

To change the Context Explorer time range:

: Admin/Any Security Analyst

1. From the Show the last drop-down list, select a time range.
2. Optionally, to view data from the new time range, click Reload.

All sections of the Context Explorer update to reflect the new time range.

Clicking Apply Filters also applies any time range updates.

Minimizing and Maximizing Context Explorer Sections

: FireSIGHT

You can minimize and hide one or more sections of the Context Explorer. This is 

useful if you want to focus on only certain sections, or if you want a simpler view. 

You cannot minimize the Traffic and Intrusion Event Counts Time Graph.
Note that Context Explorer sections retain the minimized or maximized states 

that you configure even if you refresh the page or log out of the appliance.

To minimize a Context Explorer section:

: Admin/Any Security Analyst



Click the minimize icon (

) in a section’s title bar.
