How do I rename a hostname in Splunk?

Hi, How do I rename hostname in Splunk?

I am trying to enroll a particular syslog in Splunk. I want to rename a hostname from
a => b
c => d

How could I achieve this?

Thanks,
Dinesh

It would help if you would provide a bit more concrete info on what you really want to rename rather than such an abstract example, but the basics work like below (assuming you want to rename certain specific host values and not generically want to rename all host values for a certain source/sourcetype).

in props.conf

[host::a]
TRANSFORMS-rename_host = rename_host_a

in transforms.conf

[rename_host_a]
REGEX = .
FORMAT = host::b
DEST_KEY = MetaData:Host

For syslog, this is generally done with host_segment in indexes.conf. You must configure syslog to write the originating host as part of the path to the files.
