Find a device
The ExtraHop system automatically discovers devices such as clients, servers, routers, load balancers, and gateways that are actively communicating with other devices over the wire. If you want to see network activity associated with a specific device, you can search for your device in the Discover or Command appliance, and then view traffic and protocol metrics on a protocol page.
- Perform a general search from the global search field at the top
of the page.
- Perform a detailed search from the device
list page in the Metrics section of the ExtraHop Web UI, where you can
filter search results by device attributes.
- Perform a search by protocol activity from an activity group.
- Perform a search for peer devices talking to a device.
Search for a device by details
You can create a detailed search for a device based on information observed over the wire, such as IP address, MAC address, hostname, or protocol activity. You can also search by customized information such as device tag or custom names associated with the device.
This procedure shows you how to perform a detailed search from the device list page in the Metrics section of the ExtraHop Web UI.
Next steps
- Investigate additional metrics by protocol by selecting another protocol in the left pane
- Change a device name
Search for devices by protocol activity
Activity groups contain devices that are automatically grouped together based on observed protocol traffic over the wire. Searching for a device within an activity group helps you quickly locate a client or server that is associated with a protocol, or discover a decommissioned device that is still actively communicating over a protocol.
Next steps
- Investigate additional metrics by selecting another protocol in the left pane
- Change a device name
Search for peer devices
If you want to know which devices are actively talking to each other, you can drill down by Peer IPs from a device or device group protocol page.
