Extracting multi-level host name

smhsplunk — Tue, 29 Sep 2020 11:07:52 GMT

I would like to extract both directory and subdirectory information while importing data.

So basically the directory structure is like this

monitor:///data/host_name_first_part/host_name_second_part/*.gz

So in the input.conf I can use either host_segment=2 or host_segment=3
but cannot extract both the information, how can I extract both these information.

I am using unique index name for the data, sourcetype is defined in props.conf
how can extract the host names (separately) so that I can also use them in the search command
(i.e. I can use host_segment as host in the search command)

You can setup search time field extraction (on your Search Head) to have both the segments extracted in separate fields. Once you've the field extraction setup, you can use them i the search.

See these for more info on field extraction

Not sure if this is something which will work for you, but you can use host_regex in inputs.conf, instead of host_segment, to set the host with both the segment values.

You could use a rex command like this

rex field=source "data\/(?<Field1>\w+)\/(?<Field2>\w+)\/"
