Services
These services run in the background and perform functions that do not require user input. These services
can be started and stopped through the Administration settings.
Enable or disable the Web Shell
The Web Shell provides access to the ExtraHop command-line interface (CLI). By default this service
is enabled so that ExtraHop users can click the Launch Shell link in the upper right corner of the
Administration settings and type commands. For more information, see the ExtraHop Command-line
Reference .
Enable or disable the Management GUI
The Management GUI provides browser-based access to the ExtraHop system. By default, this
service is enabled so that ExtraHop users can access the ExtraHop system through a web browser. If
this service is disabled, the Apache Web Server session is terminated and all browser-based access is
disabled.
Warning: Do not disable this service unless you are an experienced ExtraHop
administrator and you are familiar with the ExtraHop CLI.
Enable or disable the SNMP Service
Enable the SNMP service on the ExtraHop system when you want your network device monitoring
software to collect information about the ExtraHop system. This service is disabled by default.
•
Enable the SNMP service from the Services page by selecting the Disabled checkbox and then
clicking Save . After the page refreshes, the Enabled checkbox appears.
• Configure the SNMP service and download the ExtraHop MIB file
Enable or disable SSH Access
SSH access is enabled by default to enable users to securely log in to the ExtraHop command-line
interface (CLI).
Note: The SSH Service and the Management GUI Service cannot be disabled at the
same time. At least one of these services must be enabled to provide access to the
system.
Enable or disable the SSL Session Key Receiver (Discover appliance only)
You must enable the session key receiver service through the Administration settings before the
ExtraHop system can receive and decrypt session keys from the session key forwarder. By default,
this service is disabled.
Note: If you do not see this checkbox and have purchased the SSL Decryption license,
contact ExtraHop Support to update your license.
Configure the SNMP service
Configure the SNMP service on your ExtraHop system so that you can configure your network device
monitoring software to collect information about your ExtraHop system through the Simple Network
Management Protocol (SNMP). For example, you can configure your monitoring software to determine how
much free space is available on an ExtraHop system and send an alert if the system is over 95% full. Import
the ExtraHop SNMP MIB file into your monitoring software to monitor all ExtraHop-specific SNMP objects.
