Custom devices are manually created from a Command or 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 your 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
Discovery ID for the custom device always remains in the ExtraHop system.
-
Log into the Web UI on a Command or Discover appliance.
-
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, appliance, 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 still access custom
device data from previous time intervals until the datastore
becomes full.
- 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.
