Hello Splunkers,

I'm having a little difficulty getting a regex on Splunk to not index a specifc URL. I tried many types of regexes, but none of them work. Below is the URL:

hxxps://xxcomputer.drmtz.com.br

Could you help me?

thanks.

You could do this in props.conf:

[your_sourcetype]
...
TRANSFORMS-null = filter_url

And in transforms.conf:

[filter_url]
REGEX = https://\d+computer.drmtz.com.br
DEST_KEY = queue
FORMAT = nullQueue

That'll send events containing that URL to /dev/null. I've assumed that the xx stands for a number. Note, this will catch and drop every event containing that string anywhere in its raw text.
Remember to restart your indexers after making this change.
