Fix Recommendation

To configure a profile to apply syslog servers to all NSX Edge Nodes, do the following:

From the NSX Manager web interface, go to System >> Configuration >> Fabric >> Profiles >> Node Profiles.

Click "All NSX Nodes" and then under "Syslog Servers" click "Add".

Enter the syslog server details and choose "Information" for the log level and click "Add".

or

(Optional) From an NSX Edge Node shell, run the following command to clear any existing incorrect logging-servers:

> clear logging-servers

From an NSX Edge Node shell, run the following command to configure a tcp syslog server:

> set logging-server <server-ip or server-name> proto tcp level info

From an NSX Edge Node shell, run the following command to configure a primary and backup TLS syslog server:

> set logging-server <server-ip or server-name> proto tls level info serverca ca.pem clientca ca.pem certificate cert.pem key key.pem

From an NSX Edge Node shell, run the following command to configure a LI-TLS syslog server:

> set logging-server <server-ip or server-name> proto li-tls level info serverca root-ca.crt

Note: If using the protocols TLS or LI-TLS to configure a secure connection to a log server, the server and client certificates must be stored in /var/vmware/nsx/file-store/ on each NSX Edge Node appliance.

Note: Configure the syslog or Simple Network Management Protocol (SNMP) server to send an alert if the events server is unable to receive events from the NSX-T and also if denial-of-service (DoS) incidents are detected. This is true if the events server is STIG compliant.

Check Contents

From an NSX Edge Node shell hosting the Tier-1 Gateway, run the following command:

> get logging-servers

Note: This check must be run from each NSX Edge Node hosting a Tier-1 Gateway, as they are configured individually.

or

If Node Profiles are used, from the NSX Manager web interface, go to System >> Configuration >> Fabric >> Profiles >> Node Profiles.

Click "All NSX Nodes" and verify the syslog servers listed.

If any configured logging servers are configured with a protocol of "udp", this is a finding.

If any configured logging servers are not configured with a level of "info", this is a finding.

If no logging-servers are configured, this is a finding.
