can I pass additional source info from inputs.conf

[jangid]

Is it possible to pass extra info from inputs.conf?

e.g. [inputs.conf]

[default]
host = my_host

[monitor://somepath]
sourcetype = my_source
additional_info = my_additional_info

I want this additional info from all the forwarder, due to some reason I can not use host name.

Thanks

You need to set custom fields. Reference below URL.
But this is not recommended by Splunk.

Generally you should use custom fields at search time, editing props.conf or transforms.conf.

this is my custom information. I want to add this information along with sourcetype and is should be searchable. similar to sourcetype, source and host.

From the splunk documentation there is no additional parameters can be passed. But what is the difference between the sourcetype and additional_info? it's the same if we use in search.
