So I am looking to join results of 2 searches and as I can see on docs.splunk there are various ways to join
I am looking for difference between join and search command specially. Can someone elaborate please?
The Jogin command allows you depends on a field to bring two groups of search results together.
Example: search one have a result with the field IP-address and in the second search the results have a field IP-address, too.
If in both results the value of IP-adress equals the join will bring both result events together.
Result 1: IP-Adresse =192.168.1.1 and result 2 IP-address 192.168.1.1 will be joined.
Result 1: 18.104.22.168 and Result 2: 192.168.1.1 will Not joined.
Hope this helps
There is no as such relation with
search command but yes you can use
search command in subsearch to retrieve events .
You do not need to specify the
search command at the beginning of your search criteria.
When the search command is not the first command in the pipeline, the search command is used to filter the results of the previous command and is referred to as a subsearch.
Lets try an example:
Try run this anywhere search:
index=_internal|fields host source|join host [search index=_internal|fields host sourcetype]
Here you are joining two indexes i.e. _internal by the common/primary field
host and returning the events with fields
but if you try to run this search without search command:
index=_internal|fields host source|join host [index=_internal|fields host sourcetype]
it will give an error as
Unknown search command 'index' so the first command in a subsearch must be a generating command such as
tstatsetc. to retrieve events .
Hope this helps!
