Import

The Import page lets you import data from multiple different sources, and in multiple formats.

Import page — Figure 1. Import page

Import nodes

This feature lets you bind fields from a comma-separated value (CSV) files to Nozomi Networks fields so that you can add nodes (flag create non-existing nodes), or enrich existing ones. For each modified node, the file must include a row with columns that specify the additional data.

Note:

Some special fields and confirmed media access control (MAC) addresses are restricted to specific values and so they might not be overwritten.

Import variables

This feature lets you add new variables (flag create non-existing variables), or to enrich existing variables. For each modified variable, the file must include a row with columns that specify the additional data.

Import asset types

This feature lets you enlarge the built-in set of asset types with a set of new custom types. The CSV file should include a header row labeled Name and the list of asset type names in the following rows, one per row. A name identifies each asset type. This means that, during the import process, duplicate names are ignored and notified.

Table 1. Default asset types
actuator	inverter	printer_scanner
audio_video	IO_module	radio_transmitter
AVR	IOT_device	robot
barcode_reader	light_bridge	router
camera	media_converter	RTU
computer	medical_imager	sensor
controller	meter	server
digital_io	mobile_phone	switch
drone	network_security_appliance	tablet
DSL_modem	OT_device	time_appliance
firewall	other	UPS
gateway	PDU	VOIP_phone
HMI	PLC	WAP
IED	power_generator
infusion_system	power_line_carrier

Import configuration / project file

This feature lets you import a project file. The information written in the project file is added to the asset data.

Note:

For XML Profinet GSDML, you can import an eXtensible Markup Language (XML) Profinet GSDML file that describes a physical device. Information in the file lets Guardian extract and display information about the device configuration when device configuration packets are displayed in traffic.

Import content pack

You can use the Export page to export data in content packs and then you can use the Import page of a different machine to import them. For more details, see Export.

Import Arc data archive

When Arc is in Offline mode, the data is collected locally and then exported in an archive file from the machine. The archive file can then be manually imported into Central Management Console (CMC), Guardian, or Vantage.
