![]() Now create new index and give index name same as given in inputs. Now, open Splunk web interface of indexer and go to settings => indexes # vi nfĪlways follow this format to configure nf How to configure a universal forwarder to add multiple fields to events being forwarded via meta Tags: meta nf splunk-enterprise universal. To extract fields from data, need to configure nf and inside it we have to write regular expressions. So lets start with configuring nf # vi nf Then deploy the configuration files in indexer or heavy forwarder. ![]() Now configure nf # vi nfĪdd the following lines : # cd /opt/splunkforwarder/bin/etc/system/local The app is loaded from the DS so that is where you should make changes. The nf file(s) will be on the forwarders, either in the same app or a different one. The app is uploaded to the Splunk Cloud UI and is distributed to indexers automatically. Lets start with custom fields at index-time.įor example, machinelog.log stored at /tmp directoryĪt first open Universal Forwarder server and go to the $SPLUNK_HOME/etc/system/local directory. The nf file will be in the fluentd app on the indexers. Splunk can extract the following fields at index time: ![]() Today, In this article we will learn how to extract fields at index-time. It increases our search performance as well. The tag is a search-time activity and cant be assigned in nf. In these cases, Field extraction at index-time makes our job easy. But sometimes we get unstructured data from some resources or maybe we have some restrictions on Indexing capacity limit and more over we want to work on extracted fields only. In general, we extract fields at search-time. ![]()
