Custom
devices are manually created in the Discover appliance and can be configured to collect
metrics for traffic observed across multiple IP addresses and ports. If a large number of
custom devices is affecting ExtraHop system performance, you can delete or disable a custom
device.
When you delete or disable a custom device, the device becomes inactive, which
means that the ExtraHop system stops collecting metrics for that device. The unique ID
for the custom device always remains in the ExtraHop system.
-
Log into the Web UI on a Discover appliance.
-
Click the System Settings icon
and then click Custom
Devices.
-
Search for the custom device.
The Filter text box above the table supports substring matching and regular
expressions.
-
Select the checkbox next to the device(s) and then complete one of the
following steps:
- Click Disable. The selected device becomes
inactive and is removed from the full analysis device count. You can still
access custom device data from previous time intervals
until
the datastore becomes
full.
- Click Delete to permanently remove the device
configurations. You cannot enable a device that has been deleted.
