Custom devices are manually created on an ExtraHop system to collect metrics for
traffic observed across multiple IP addresses and ports. If a large number of custom devices
is affecting your system performance, you can delete or disable a custom device.
Before you begin
Full privileges or higher are required to
create or delete a custom device.
- When you delete or disable a custom device, the device becomes inactive, which
means that the system stops collecting metrics for that device.
- When you delete or disable a custom device, the device continues to appear as an
asset until all metrics collected for that device are overwritten in the local
datastore.
- When you delete a custom device, the unique Discovery ID for the custom device
always remains in the system and cannot be applied to a new custom device.
-
Log in to the ExtraHop system through
https://<extrahop-hostname-or-IP-address>.
-
Click the System Settings icon and then click Custom
Devices.
- (Optional):
From the filter text box, search for the custom device.
The filter text box supports substring matching by custom device name,
description, status, sensor, and Discovery ID.
-
From the table, select the custom device that you want, and then complete one
of the following steps:
- From the configuration options, clear the Custom Device
Enabled checkbox. The selected device becomes inactive and
is removed from the full analysis device count. You can re-enable the custom
device anytime, and you can still access custom device metrics from previous
time intervals until they are overwritten in the local datastore.
- From the top of the page, click Delete Device,
and then click Delete Custom Device from the
confirmation window. The selected custom device is permanently removed from
the ExtraHop system and cannot be restored.
