You can set up several backup Log Servers for each Log Server.

For more details about the product and how to configure features, click Help or press F1.

Steps

Select Dashboard > Servers / Devices.
Select Tools > New > Server > Log Server.
In the Name field, enter a unique name.
In the IP Address field, enter the IP address.
(Optional) If NAT is used to translate addresses in communications between this server and other SMC components, define the Location and Contact Address.
(Optional) Change the Log Server’s TCP Port number if necessary. We recommend always using the default port 3020 if possible.

Note: If you use a non-standard port, add rules to allow communications from the engines to the Log Server ports, even when using the Firewall Template policy.
(Optional) If you do not want the Log Server to gather statistical information for monitoring and reports, select Exclude from Log Browsing, Statistics and Reporting.

Tip: You might want to select this option if the Log Server is not used for daily operations.

You must already have an Elasticsearch cluster deployed and configured in your environment.
Elasticsearch Cluster	Shows the Elasticsearch cluster that receives log data from the SMC server.
Client Authentication Settings	Defines how the connection between the server and the Elasticsearch cluster is secured. Inherited — The SMC server uses the settings defined in the Elasticsearch Cluster element. Override — The SMC server uses custom settings.
TLS Certificate	(When Override is selected.) Specifies the TLS certificate that is used to secure the connection between the SMC server and the Elasticsearch cluster. Use Internal Certificate — The SMC server uses its own internal certificate. Use Imported Certificate — The SMC server uses the specified external certificate. No Client Authentication — The connection is not authenticated.

Option	Definition
Monitoring tab
Log Server	The Log Server that monitors the status of the element.
Status Monitoring	When selected, activates status monitoring for the device. You must also select the Probing Profile that contains the definitions for the monitoring. When you select Status Monitoring, the element is added to the tree in the Home view.
Probing Profile	Shows the name of the selected Probing Profile. Click Select to select a Probing Profile element.
Log Reception	Activates syslog reception from this device. You must select the Logging Profile that contains the definitions for converting the syslog entries to SMC log entries. You must also select the Time Zone in which the device is located. By default, the local time zone of the computer you are using is selected.

Option	Definition
Audit Forwarding or Log Forwarding tab Click Add to add a row to the table, or Remove to remove the selected row.
Target Host	The Host element that represents the target host to which data is forwarded. Double-click to open the Select Host dialog box.
Service	Click the cell, then select the network protocol for forwarding data from the drop-down list. The following network protocol options are supported: TCP UDP TCP with TLS Kafka Kafka with TLS Note: For log data in IPFIX or NetFlow v9 format, UDP is the only available network protocol. You might have to define an Access rule that allows traffic to the target host. In this case, make sure that the Service you select is also used as the Service in the Access rule.
Port	The Port that is used for forwarding data. Double-click to edit the cell. The default port is 2055. For log data, the default port used by IPFIX/NetFlow data collectors is 2055. Note: You might have to define an Access rule that allows traffic to the target host. In this case, make sure that the Port you select is also used as the Port in the Access rule.
Format	Click the cell, then select the data forwarding format from the drop-down list. CSV — Forwards in comma separated value format. Short CSV — Forwards truncated data in comma separated value format. (Log Server only) XML — Forwards in XML format. JSON — Forwards log data in JSON format. CEF — Forwards in common event format. LEEF — Forwards in log extended event format. NetFlow v9 — Forwards in a format that is compatible with NetFlow v9. (Log Server only) IPFIX — Forwards in a format that is compatible with IPFIX. (Log Server only) McAfee ESM — Forwards in a format that is compatible with McAfee ESM. Note: You can customize the interval by which the NetFlow template is sent. This is done by modifying the parameter `NETFLOW_TEMPLATE_INTERVAL_SECONDS=<seconds>` in the SMC Log Server configuration file. The default interval is 300 seconds.
Data Type	Click the cell, then select the applicable data type option from the drop-down list. The log data for the selected data type only is forwarded to the target host.
