See Introduction to lookup configuration and Configure KV store lookups. See Create and maintain search-time field extractions through configuration files. Lookup_ip = dnsLookup ipaddress OUTPUT host When you set up the lookup in nf, use ipaddress where you would otherwise use ip: In the nf file where you defined the extraction, add a line that defines ipaddress as an alias for ip, as follows:ĮXTRACT-extract_ip = (?\d) You created a lookup for an external static table CSV file, where the field you extracted at search time as ip is referred to as ipaddress. Restart Splunk Enterprise for your changes to take effect.Įxample of field alias additions for a lookup.You can include multiple field alias renames in one stanza.Add the following line to a stanza in nf:.nf Expose Correct Answer Question 15 When configuring HTTP Event Collector (HEC) input, how would one ensure the events have been indexed A. See about tags and aliases for more information on aliases. Which configuration file would be used to forward the Splunk internal logs from a search head to the indexer A.Note: Splunk Enterprise supports single value fields only. Use the latter directory to make it easy to transfer your data customizations to other index servers.) You can define aliases for fields that are extracted at index time as well as those that are extracted at search time.Īdd your field aliases to nf, which you edit in $SPLUNK_HOME/etc/system/local/, or your own custom app directory in $SPLUNK_HOME/etc/apps/. See Configure CSV and external lookups and Configure KV store lookups. This can be helpful if one or more fields in the lookup table are identical to fields in your data, but are named differently. Perform field aliasing after key-value extraction but before field lookups so that you can specify a lookup table based on a field alias. An alias does not replace or remove the original field name. For example, the field vendor_action can be aliased to action or message_type, but not both. A field can have multiple aliases, but a single alias can only apply to one field. Setting up character set encoding Defining manual filed extarction regex Allowing processing of binary files. You can assign one or more tags to any extracted field, including event type, host, source, or source type.įield aliases are an alternate name that you assign to a field, allowing you to use that name to search for events that contain that field. nf is used to define following configurations in splunk: Configuring timestamp recognition Convertig timeformat to our default timeformat Configuring linebreaking for multiline events. To help you search for these groups of fields, you can assign field aliases to their field values. In your data, you might have groups of events with related field values.
