How can I override an index name based on sourcetype?

[rphillips_splk]

I want to override the index name of my events (assigned at the forwarder) with a new index name based on sourcetype.

[rphillips_splk · Accepted solution]

This can be done at the heavy forwarder or indexer:

On your indexer or heavy forwarder:

# etc/system/local/transforms.conf 
[overrideindex]
DEST_KEY =_MetaData:Index
REGEX = .
FORMAT = my_new_index


#etc/system/local/props.conf 
[mysourcetype]
TRANSFORMS-index = overrideindex

[rphillips_splk]

you must have the index already configured on the indexers in indexes.conf before sending events to the new index.

Can I do this based on specific host name, if yes, how?

Yes, you can specify a host name to be used in props.conf see the docs for more details https://docs.splunk.com/Documentation/Splunk/latest/Admin/Propsconf#GLOBAL_SETTINGS
