Send Syslog Notifications to SIEMs

Asset Manager superusers can use the CEF logging feature to send syslog output to an external viewer in a common-event format. By enabling it, all event notifications to which the superuser has subscribed can be displayed in one preferred Security Information and Event Management (SIEM) viewer such as HP ArcSight, Splunk, or QRadar.

CEF Notifications are either system-related or device-related. The system-related notifications are global and pertain to all of Asset Manager. Device notifications pertain to a particular zone.

Subscribe to receive notifications at Settings > Asset Manager Systems > CEF Notifications > System and Device tabs.

  • System notices report when an Agent, Collector, Scout, or Zone has been created, started or stopped. They also alert on license status (e.g., reminder, warning, and violation).
  • Device notices report findings about your network architecture such as when a device, edge, or node has been discovered, updated, or removed.

This section provides an example of integrating to the representative event manager HP ArcSight. 

Configure CEF Server

Enable the CEF logging feature to make Asset Manager compile all subscribed event notifications to a logging server. Here's an example of how to enable logging to a HP ArcSight console via the Asset Manager graphical user interface (GUI) or the Asset Manager command-line interface (CLI).

Configure CEF Server using the GUI

  1. Go to Settings > Asset Manager Systems.
  2. Click the CEF Notifications tab. 
  3. Identify the logging server to which you want to send event notifications.
    • Protocol: Type TCP-IPv4, UDP-IPv4, TCP-IPv6, UDP-IPv6 
      Note: Use TCP-IPv4 or UDP-IPv4 for HP ArcSight.) 

    • Host Name or IP Address: Must be an IPv4-type IP address 

    • Port number: Must be a valid integer

  4. When you are ready to send CEF formatted event notifications, click the CEF Enabled checkbox.
  5. Click Submit.
    A message displays, indicating that your configuration settings were saved.
    Asset Manager is now configured to display CEF-formatted syslog output in your ArcSight console.

Configure CEF Server using CLI

  1. Log in the Command-Line Interface (CLI).
    1. Open a host or server that supports SSH.  
    2. At the prompt, type ssh admin@<yourservername> and press Enter.
    3. Enter your password (i.e., admin) and press Enter.
  2. At the command prompt, type  

    log cefserver <enable/disable> <protocol> <IP address> <port number> and press Enter.

    • Protocol: Type TCP-IPv4, UDP-IPv4, TCP-IPv6, UDP-IPv6  (Note:  Use TCP-IPv4 or UDP-IPv4 for HP ArcSight.) 

    • IP Address: Must be an IPv4 type IP address 

    • Port number: Must be a valid integer 

    • Enable: Enables the CEFserver 

    • Disable: Disables the CEFserver

Asset Manager is now configured to display CEF-formatted syslog output in your HP ArcSight console.

Configuring CEF-Formatted Syslog Output

  1. On the CEF Notifications tab, click the tab for the type of CEF Notifications to which you want to subscribe: either System or Device.
  2. To edit the prioritization of the event and whether you subscribe to it, click Edit and update the form.
    • Subscribed: Indicates whether or not you've opted to send notifications of the particular event type. 
    • Name: Name of the event 
    • Priority: Indicates level of severity: informational, alert, or warning. 
    • Event Type: The Event Type is the predefined category of event.
  3. To Add a device notification, click Add and update the form.
  4. To apply additional filters to your device notifications, update this form:
