Network inputs can be manually added to the inputs.conf configuration files. Edit $SPLUNK_HOME/etc/system/local/inputs.conf and add your input. You will need to restart Splunk after modifying the file. For example, to enable UDP port 514 use the following code:
[udp://514] sourcetype = syslog
It is best practice to not send syslog data directly to an indexer. Instead, always place a forwarder between the network device and the indexer. The Splunk forwarder will be set up to receive the incoming syslog data (inputs.conf) and will load balance the data across your Splunk indexers (outputs.conf). The forwarder can also be configured to cache the syslog data in the event communication to the indexers is ...
