set filename as host

[indeed_2000]

Hi
I have log file that copy on splunk server every day with below structure:

/data/appserver/ACC/20200617/log.customer1.20200617.bz2
/data/appserver/ACC/20200617/log.customer2.20200617.bz2
/data/appserver/ACC/20200617/log.cus1.20200617.bz2
/data/appserver/ACC/20200617/log.cus2.20200617.bz2
/data/appserver/ACC/20200617/log.cus3.20200617.bz2

now I want splunk consider everything between two dots as host name, like this:
customer1
customer2
cus1
cus2
cus3

I try to do this throgh web ui and "Set host" = "5" :
settings > datainputs > Files & Directories > /data/appserver/ACC/

is this correct? i mean splunk consider 5's part of address?

Thanks

first: you can't extract host name, I guess.

second: try TRANSFORMS stanza
