Create a custom device
To collect metrics for a segment of traffic across multiple IP addresses and ports, you can create a custom device in the Discover appliance. Custom devices are useful for monitoring traffic outside of your local broadcast domain, such as branch offices, stores, or clinics. A single custom device counts as one device towards your licensed capacity for Advanced Analysis and Standard Analysis.
Custom devices replace the former pseudo devices feature. Any pseudo devices
created on a previous version of ExtraHop firmware will remain on your Discover
appliance until you migrate the pseudo device to a custom device. Unlike with pseudo
devices, you do not need Admin UI privileges to configure a custom device.
Important: | Custom devices affect ExtraHop system performance. |
Here are some important considerations about custom devices:
- Add a custom device to the watchlist to guarantee that the custom device receives Advanced Analysis.
- Avoid creating multiple custom devices for the same IP addresses or ports. Custom devices that are configured with overlapping criteria might degrade system performance.
- Avoid creating a custom device for a broad range of IP addresses or ports, which might degrade system performance.
- Custom devices can only be created on a Discover appliance.
- Custom devices appear in the ExtraHop system after traffic is observed that matches the IP address and port criteria that you specify.
