How to Create a Watchlist/Lookup Tables

Dear Team,

Do anyone have idea on how do we create a watchlist in ELK. In other terms lookup tables. This specifies a range of values say 50 or 100 or more in a single file. And save it as .csv or .txt

For Ex: there are around 50-100 source IP addresses and each cannot be mentioned in the condition in the query. So we put it in a file and call that file in the condition of the query.

How do we do this in creating a query in ELK, and that too in logstash.

Please throw some light if someone has come across such situation.

There is the translate filter that might work.

Thanks for sharing the link, Mark.

We tried to install the "translate filter" plug-in on the log stash 1.4.2- modified version, while installing we are getting the error-

Can only install contrib at this time... Exiting..

Suggest the possible resolution from your end.

I'd start by upgrading, 1.4 is really old.
