Hi all, I have a file lets say eachline.txt and I would like to search each line within the file against a index.
Did some reading and it appears I need to use the inputlookup command to do this? Can someone confirm if this is true and does the file need to be a csv?
My thought would I would do something like index=someindex | inputlookup eachline.txt and it would search the index in question?
Sorry, but it doesn't work like that..
There is a tutorial here on lookups: http://docs.splunk.com/Documentation/Splunk/4.3.2/User/Fieldlookupstutorial
Note that you do NOT want to set up the automatic lookup.
What you want to do is a little different than the usual application. But here is how it could work:
index="myindex" [ inputlookup yourlookupname | fields ipAddress ]
This assumes that the data is in a csv file, with a header line. And that the header for the IP address field is "ipAddress" and that ipAddress is also the field name in your index.
Each time that you want to change the list of files to search, you would need to take a minute and upload a new CSV file for the lookup.
Very important: the subsearch (within the brackets) has some limitations:
By default, the number of items returned from the subsearch is limited to 100. You can up this maximum, but the absolute maximum is 10500. To up the limit to the max:
index="myindex" [ inputlookup yourlookupname | fields ipAddress | format maxresults = 10500 ]
If your "eachline.txt" file could be more than 10500 lines long, post back and I'll propose a different solution...
