If appliances are connected to a Trellix Helix-enabled Central Management System appliance, you should prevent the Central Management System appliance from streaming their alerts to Trellix Helix and instead allow streaming directly from the connected appliances. This is recommended for all connected appliances, but is required for appliances with the HelixConnect Client enabled. Otherwise, you will be unable to take alert remediation actions for those appliances from the Trellix Helix Web UI (described in the Trellix Helix Product Guide).
Both the Central Management System appliance and connected appliances stream health statistics to Trellix Helix. The Central Management System appliance should stream health statistics for itself, but health statistics for connected appliances should be streamed directly from those appliances and not through the Central Management System appliance.
Note
Alert and health statistics streaming is disabled by default on the Central Management System appliance and connected appliances, but is enabled after Trellix Helix mode is enabled on them. This topic shows how to verify the configuration and modify it as necessary to stream directly from the connected appliances.
Log into the Central Management System CLI.
Go to CLI configuration mode:
cm-hostname > enable cm-hostname # configure terminal
Verify that streaming is disabled on the Central Management System appliance:
cm-hostname (config) # show fenotify integ helix
If the
enablefield isyes, disable streaming from the Central Management System appliance:cm-hostname (config) # no fenotify integ helix
Log into the connected appliance CLI.
Go to CLI configuration mode:
appl-hostname > enable appl-hostname # configure terminal
Verify that alert streaming is enabled on the connected appliance:
appl-hostname (config) # show datastreaming helix
If the
Helix datastreaming enabledfield isno, enable streaming from the appliance:appl-hostname (config) # datastreaming helix alert-metadata enable
Verify that health statistics streaming is enabled on the connected appliance:
appl-hostname (config) # show helix health-stats status
If the
enabledfield isno, enable streaming from the appliance:appl-hostname (config) # helix health-stats enable
Prevent the Central Management System appliance from uploading health statistics on behalf of the connected appliance:
appl-hostname (config) # no fenet dti helix service override enable
Verify that the Trellix Helix service setting is
DTI (xxx) - Managed by Appliance(notCMS).appl-hostname (config) # show fenet dti configuration
Optional: Verify whether OS changes are included in the alerts:
hostname (config) # show datastreaming helix
If the
include os-changesfield isno, enable the inclusion of OS changes:hostname (config) # datastreaming helix alert-metadata include-oschanges
