Navigating the ExtraHop System

The ExtraHop system provides access to network activity data and detection details through a dynamic and highly customizable user interface.

This guide provides an overview of the global navigation and controls, fields, and options available throughout the system. See Introduction to the ExtraHop system to learn how the ExtraHop system collects and analyzes your data.

Layout and menus

Global navigation elements are located at the top of the page and contain links to the main sections of the system. Within each section, the left pane contains links to specific pages or data.

The following figure shows both global and left pane navigation elements.

Here are definitions of each global navigation element:

Overview pages
Overview pages enable you to quickly evaluate the scope of suspicious activity on your network, learn about protocol activity and device connections, and investigate inbound and outbound traffic on your network.
  • View the Security Overview for information about security detections on your network.
  • View the Network Overview for information about active devices on your network.
  • View the Perimeter Overview for information about traffic traveling in and out of your network.
Click Dashboards to view, create, or share dashboards for monitoring any aspect of your network or applications. System dashboards give you an instant view of the activity and potential security threats on your network.
Click Alerts to view information about each alert generated during the time interval.
If your packet or flow sensor is connected to the ExtraHop Machine Learning Service, the top level navigation shows the Detections menu. Click Detections to view detections identified from your wire data. You can access stored detections even if your sensor is disconnected from the Machine Learning Service.
Note:Machine learning detections require a connection to ExtraHop Cloud Services.
Click Assets to find any application, network, or device discovered by the ExtraHop system. You can view protocol metrics for your assets, active users, or network activity by protocol.
If your ExtraHop system is configured with a recordstore, the top level navigation shows the Records menu. Click Records to query for all stored records for the current time interval. Records are structured information about transactions, messages, and network flows.
If your ExtraHop system is configured with a packetstore, the top level navigation shows the Packets menu. Click Packets to query for all stored packets for the current time interval.
Global search field
Type the name of any device hostname or IP address, application, or network to find a match on your sensor or console. If you have a connected recordstore, you can search for saved records. If you have a connected packetstore, you can search for packets.
Help icon
See help information for the page that you are currently viewing. To access the most current and comprehensive set of ExtraHop documentation, visit the ExtraHop Documentation website.
System Settings icon
Access system configuration options, such as Triggers, Alerts, Scheduled Reports, and Custom Devices, and click to view the ExtraHop system and version. Click System Notices to view a list of features in the most current version and any system notices such as expiring licenses or available firmware upgrades.
User option icon
Log in and log out of your sensor or console, change your password, select the display theme, set a language, and access API options.
Pane toggle
Collapse or expand the left pane.
Global Time Selector
Change the time interval to view application and network activity that was observed by the ExtraHop system for a specific time period. The global time interval is applied to all metrics across the system and does not change as you navigate to different pages.
Recent pages
See a list of the most recent pages you visited in a drop-down menu and make a selection to go back to a previous page. Repeated pages are deduplicated and condensed to save space.
Navigation path
View where you are in the system and click a page name in the path to navigate back to that page.
Command menu drop-down
Click to access specific actions for the page you are viewing. For example, when you click Dashboards at the top of the page, the command menu provides actions for changing dashboard properties or creating a new dashboard.

Start analyzing data

Begin your data analysis journey with the ExtraHop system by following the basic workflows listed below. As you become familiar with the ExtraHop system, you can complete more advanced tasks, such as installing bundles and building triggers.

Here are some basic ways to navigate and work with the ExtraHop system to analyze network activity.

Monitor metrics and investigate interesting data
Good starting points are the Network Activity dashboard and Network Performance dashboard, which show you summaries of important metrics about application performance on your network. When you see a spike in traffic, errors, or server processing time, you can interact with dashboard data to drill down and identify which clients, servers, methods, or other factors contributed to the unusual activity.

You can then continue performance monitoring or troubleshooting by creating a custom dashboard to track a set of interesting metrics and devices.

Check out the following walkthroughs to learn more about monitoring data in dashboards:

Search for a specific device and investigate related metrics and transactions
If you want to investigate a slow server, you can search for the server in the ExtraHop system by device name or IP address and then investigate the server's activity on a protocol page. Was there a spike in response errors or requests? Was server processing time too high or did network latency affect the rate of data transfer? Click on different protocols on the Devices page to investigate more metric data collected by the ExtraHop system. Drill down by peer IP addresses to see which clients or applications the server talked to.

If your ExtraHop system is connected to a recordstore, you can investigate entire transactions that the server participated in by creating a record query.

Check out the following walkthroughs to learn more about exploring metrics and records:

Get visibility into changes to your network by searching for protocol activity
You can get a top-down view of your network by looking at built-in protocol groups. An protocol group is a collection of devices automatically grouped together by the ExtraHop system based on the protocol traffic observed over the wire. For example, you can find new or decommissioned servers that are actively communicating over a protocol by creating an activity map.

If you find a collection of devices that you want to continue monitoring, you can add a device tag or custom device name to make those devices easier to find in the ExtraHop system. You can also create a custom device group or a custom dashboard to monitor device group activity.

Advanced workflows for customizing your ExtraHop system

After becoming familiar with basic workflows, you can customize your ExtraHop system by setting up alert notifications, creating custom metrics, or installing bundles.

Set up alerts
Alerts track specified metrics to notify you of traffic deviations that might indicate an issue with a network device. Configure a threshold alert to notify you when a monitored metric crosses a defined value. Configure a trend alert to notify you when a monitored metric deviates from the normal trends observed by the system.
Build a trigger to create custom metrics and applications
Triggers are custom scripts that perform an action upon a pre-defined event. Triggers require planning to make sure a trigger doesn't negatively impact system performance.
